Valeton GP-150 presets and settings
Floor unit with two footswitches, a built-in expression pedal, a colour screen and a 3000 mAh battery. Twelve modules at once, in any order, from 58 amp models and over 200 effects, plus a loader for NAM captures and up to 20 cabinet IRs.
⚡ Match a tone on this gearHow do you dial in a specific tone on a Valeton GP-150?
A multi-effects unit gives you the whole chain in one box, which means the order of the blocks is as much of the answer as the values inside them. Settings for the Valeton GP-150 name the amp model, the block order and the parameters together, rather than handing you numbers with no chain to put them in.
Name the song you are chasing in the tone matcher and Tonelify returns the settings for this exact multi-effects unit, not the settings the original artist used. Those are two different things: the recording was made on gear most players do not own.

Starting settings on the Valeton GP-150
Values as the unit's screen shows them, on its own scale; each drawn knob shows that value's share of the range. They are where to begin, not Valeton's numbers: pick the amp model first, then move one control at a time from here.
Clean
Dark Twin, Valeton's model of the Fender '65 Twin Reverb. Gain 30, Bass 50, Middle 50, Treble 60, Bright off. Valeton's effect list calls Gain the pre gain and Volume the post gain, so keep Gain low for a clean that stays clean and set the level with Volume. Spring, the vintage spring reverb in RVB, with its Mix low suits it. For another clean, the factory SnapTone file Dark DLX is a capture of a Fender '65 Deluxe Reverb with a 2x12, and J-120 CL, based on the Jazz Chorus, has no separate Volume: its Gain sets the output.
- Gain 30
- Bass 50
- Middle 50
- Treble 60
Bright off; set the level with Volume.
Edge of breakup and blues
Bellman 59B, the Bright channel of a Fender '59 Bassman, which Valeton lists as an Overdrive type at its default settings. Gain 50, Bass 45, Middle 60, Treble 55, Presence 50. For a push without more amp gain, put Penesas, Valeton's model of the Klon Centaur, in PRE before the amp with its Gain low and its Volume up. Foxy 30TB, the VOX AC30HW's Top Boost channel, is the other way in: it has Bass and Treble but no Middle, a Tone cut control, and Char, which picks Cool for lower gain or Hot for higher. Among the factory SnapTone files, Dark OD and Band OD are captures of a 1965 blackface Bassman and a 1964 Bandmaster in their overdrive tones.
- Gain 50
- Bass 45
- Middle 60
- Treble 55
- Presence 50
Penesas in PRE for a push.
Classic rock
UK 800, Valeton's model of the Marshall JCM800. Gain 60, Bass 50, Middle 65, Treble 60, Presence 50. Keep the mids up: rock guitar sits in the midrange, and scooping it is the usual reason a patch sounds thin next to a band. With Auto CAB Match on, the cabinet changes with the amp model; UK Vintage 4x12, Valeton's Marshall 1982B, is a good one to check it against. For older Marshalls there are six JTM45 and JMP50 models, normal, bright and with the inputs jumped, plus UK SLP, the 1959HWTM reissue, and Bog BlueV, the Bogner XTC blue channel, which Valeton describes as a loud plexi voice.
- Gain 60
- Bass 50
- Middle 65
- Treble 60
- Presence 50
Keep Middle above Bass.
Metal
Mess DualM, Valeton's model of a Mesa/Boogie Dual Rectifier in Modern mode. Gain 65, Bass 55, Middle 40, Treble 60, Presence 55. Turn on NR with Gate 3, which has Threshold, Attack, Release and Hold, and raise Threshold until the hiss stops between notes. For tighter palm mutes, put Scream OD, a Tube Screamer-style model, in DST before the amp with its Gain low, and take the amp's Gain down a step. EV 51, the Peavey 5150's Lead channel, and Power LD, an ENGL Powerball II, are the other modern high-gain amps, and the factory SnapTone files add EV53 CH3, an EVH 5150III's third channel, and Rev Red, a Revv Generator 120 MKIII's red channel.
- Gain 65
- Bass 55
- Middle 40
- Treble 60
- Presence 55
Gate 3 on, Scream OD in DST.
Lead
Mess4 LD, Valeton's model of the Mesa/Boogie Mark IV Lead channel. Gain 65, Bass 50, Middle 60, Treble 55, Presence 55. Add BBD Delay S, the stereo analog delay in DLY, with its Mix low so the repeats sit behind the notes. For a solo that switches on with one press, hold footswitch B to change to Stomp Mode and give footswitch A the DST and DLY modules: each footswitch can switch up to three. The built-in pedal works the VOL module in its blue state by default; press the toe hard to change to the orange state, and assign that to V-Wah's position for a wah.
- Gain 65
- Bass 50
- Middle 60
- Treble 55
- Presence 55
BBD Delay S in DLY, Mix low.
Bass and acoustic
For bass, the AMP module has Classic Bass, based on the Ampeg SVT, whose Midrange control picks its centre from 220 Hz, 450 Hz, 800 Hz, 1.6 kHz or 3 kHz, Mini Bass on the Ampeg B-15, Foxy Bass on the VOX AC-100, Mess Bass on the Mesa/Boogie Bass 400 and Bass Pre on the Alembic F-2B. DST adds Black Bass, after the Darkglass Microtubes B7K, Bass Hammer, after the Aguilar Tone Hammer, and Bass OD; there is B-Wah, B-Jet, Bass EQ 1 and eight bass cabinets, and six of the factory SnapTone files are bass amps with their cabinets, from AMPG BASS, an Ampeg SVT Classic with a 6x10, to SBE BASS, an EBS HD350. For an acoustic, AC Pre is based on the AER Colourizer 2: an EQ Gain of 50 leaves it neutral and a Balance of 0 turns its tone control off. AC Sim in PRE makes an electric sound acoustic in Standard, Jumbo, Enhanced or Piezo mode, and CAB has five acoustic bodies, from a dreadnought to a jumbo.
Valeton GP-150 amp list
The AMP module has 58 models: 52 for guitar, 5 for bass and 1 acoustic preamp. Each row gives the amp Valeton names as the basis, in the manual's order. The type is how Valeton describes the model at its default settings: it says the tone changes as you turn up the Gain, and that drive types short of high gain are all listed as Overdrive. Where the manual's own entry is unclear, the row says so rather than guessing.

Valeton GP-150 questions
What amps are in the Valeton GP-150?
58 in the AMP module: 52 guitar amps, 5 bass amps and an acoustic preamp. Valeton's effect list bases them on amps including the Fender Tweed Deluxe (Tweedy), '59 Bassman (Bellman 59N and 59B) and '65 Twin Reverb (Dark Twin), the VOX AC30HW (Foxy 30N and 30TB), the Marshall JTM45 (UK 45), JMP50 (UK 50), JCM800 (UK 800) and JCM900 (UK 900), the Matchless Chieftain (Match CL and OD), the Mesa/Boogie Lone Star, Mark IIC+, Mark IV and Dual Rectifier, the Bogner Shiva and XTC, the Grindrod Pendragon PG20C (Knights), the Soldano SLO100 (Solo100), the Dr. Z Maz 38 Sr. (Z38), the Bad Cat Hot Cat 30 (Bad-KT), the Orange Rockerverb 100 (Juice R100), the Peavey 5150 (EV 51), the ENGL Savage 120 and Powerball II and the Diezel VH4 (Dizz VH). On top of these come 50 factory SnapTone files, captures of further amps and pedals.
What is the difference between the Valeton GP-150 and the GP-180?
The sounds are the same: both manuals list the same 58 amp models, 36 cabinets and 50 factory SnapTone files, and both units have 12 modules, 200 patch slots, a 180 second looper and a 3000 mAh battery. The GP-150 has two footswitches and a built-in expression pedal, with one EXP/FS jack that also takes MIDI in. The GP-180 has three footswitches, the third for CTRL or tap tempo, ten module buttons, one for each module but SnapTone and VOL, no built-in pedal and two EXP/FS jacks, one MIDI in and one MIDI out, and its tuner can bypass in analog or DSP. Valeton gives the GP-150 as 200 mm by 139 mm by 55 mm at 958 g, and the GP-180 as 181 mm by 139 mm by 52 mm at 843 g.
Is the Valeton GP-150 a new GP-100?
Valeton says it builds on the GP-100's form, two footswitches with an expression pedal, and calls it a complete evolution rather than a refresh. What the GP-150's manual and product page list includes SnapTone for NAM captures, a 48 kHz sample rate, 12 modules in a chain you can reorder, 200 patch slots, a built-in 3000 mAh battery, Bluetooth, a 180 second looper and a TRRS headset jack. The GP-100 page on this site covers that unit from its own manual.
What is SnapTone on the GP-150?
Valeton's format for NAM (Neural Amp Modeler) captures. The SnapTone module, shown as N→S, loads a file converted from a NAM file and has its own Gain, VOL, Bass, Middle, Treble and Presence. The GP-150 comes with 50 files and stores up to 100: 7 pedals, 28 amp heads, 9 guitar amps with a cabinet and 6 bass amps, each modelled after a named unit, such as the Analog.Man King of Tone (KOT OD) or an EVH 5150III's third channel (EV53 CH3). Files are managed in batches in the Valeton Suite software.
How many effects can the GP-150 run at once?
Up to 12, one in each module: NR, PRE, WAH, DST, SnapTone, AMP, CAB, EQ, MOD, DLY, RVB and VOL, which is the default order. Hold the PARA knob on a module in the edit screen to move it. The real limit is processing: the edit screen shows the chain's DSP load and each effect's share, an effect that would take it over 100% is greyed out, and Valeton suggests setting unused modules to None to free it. Valeton counts over 200 effects.
How do the footswitches work on the GP-150?
In Patch Mode, with blue rings, footswitches A and B step through patches. Hold B to change to Stomp Mode, where the rings show green or red and each footswitch turns its modules on and off: up to three per footswitch and six per patch, assigned in the edit screen. Hold A on the main screen for tap tempo, from 40 to 300 BPM. Press A and B together for the tuner, and keep holding them for more than two seconds for the looper.
How do you set up the expression pedal on the GP-150?
The built-in pedal has two states, EXP 1-A with a blue light and EXP 1-B with an orange one; press the toe hard to change between them. By default EXP 1-A works the VOL module, so the pedal starts as a volume pedal. Each state can move up to three parameters at once, each with its own minimum and maximum from 0 to 100, set under EXP Settings in the patch settings. EXP 2 is an external pedal on the EXP/FS jack, and both can be calibrated in the global settings. To use it as a wah, Valeton says to assign the wah's position parameter first.
Should you use the GP-150's amp models with a guitar amp?
Into the front of a guitar amp, Valeton says to keep the AMP and CAB modules off. In the amp's effects loop, between its send and return, it recommends using only EQ, MOD, DLY and RVB, again with AMP and CAB off. Into the amp's return alone, the AMP or SnapTone module does the preamp's job with the amp's power amp: keep CAB off, or turn on No CAB Mode, which can drop the cabinet from the left and right outputs separately. Into headphones, an interface, monitors or a PA, keep AMP and CAB on and No CAB Mode off.
Can you load your own IRs into the GP-150?
Yes: 20 slots for third-party cabinet IRs of 1024 or 2048 points, User IR 1 to 20 in the CAB module, managed in the Valeton Suite software. The factory cabinets have a Precision control that switches them from 1024 to 2048 points, plus Low Cut and High Cut.
How do you save a patch on the GP-150?
Press SAVE, turn the PARA knob to choose the slot, name it with the three knobs, then press SAVE again. Hold SAVE to save straight over the current patch. An asterisk beside the patch number means unsaved changes, which are lost if you change patch or switch off. Auto Save, off by default, saves every change as you make it and cannot be undone. There are 200 slots with 100 factory patches, and a factory reset can restore the factory patches, the global settings or everything.
Does the Valeton GP-150 have a battery?
Yes, a built-in 3000 mAh battery, which Valeton's product page says runs for over six hours at screen brightness II. It charges through the 9V DC jack or the USB-C port, which takes PD fast charging. Below 20% a warning appears; below 5% it cannot be dismissed and the unit gives no sound. With a 9V adapter connected, the USB-C port can also charge a phone, set under Power Options in the USB settings.
How long is the looper on the GP-150?
180 seconds. Hold footswitches A and B together for more than two seconds to open it. Before the effects it records a dry mono signal, so you can change patch and hear the loop through it; after them it records in stereo, which halves the time to 90 seconds. It can start recording when you start playing and keep time with the drum machine. Valeton calls it an auxiliary tool: what you record is not saved.
Can the GP-150 be used as an audio interface?
Yes, over USB-C with a computer or a phone. In Normal Mode it has 6 inputs and 4 outputs: the effects chain, a wet-only pair and a loopback pair for sound from other apps, with the dry signal able to go back through the effects. Legacy Mode is 2 in and 2 out, for phones over OTG, without MIDI and without the computer software. Windows needs Valeton's ASIO driver; macOS, iOS and Android need none. The PHONES/MIC jack takes a TRRS headset with a microphone, which can be recorded too, and the Global EQ does not reach the USB output.
Does the Valeton GP-150 have MIDI?
MIDI in, on the EXP/FS jack with a 1/4 inch TRS cable, set to MIDI by default, and over USB; Valeton's product page adds Bluetooth. Patches are selected with CC0 and a program change, since there are 200; CC7 sets the patch volume, CC48 to CC59 switch the 12 modules, CC69 and CC70 are the CTRL footswitches and CC75 is tap tempo. It has no MIDI out; the GP-180 does.
What power supply does the Valeton GP-150 need?
A 9V DC supply with a 5.5 x 2.1 mm centre-negative plug giving at least 1.5 A, or 5V over USB-C at 1 A or more, which can be a power bank. Valeton's manual says a third-party adapter must match the unit's requirements, since the wrong polarity is a fire risk.
How do you use the tuner on the GP-150?
Press footswitches A and B together. It shows the note and how many cents it is off, from -50 to +50, and the bars turn green when you are in tune. The three knobs set the mode, Mute or Bypass, a tuning template, and the reference A from 435 Hz to 445 Hz, 440 Hz by default. The templates are Standard, Drop D, Drop C, Drop A, Open D, Open E, Open G and four- and five-string bass. In Bypass, the USB audio is bypassed too.
What are the best Valeton GP-150 settings for metal?
Start with Mess DualM, Gain 65, Bass 55, Middle 40, Treble 60 and Presence 55, with Gate 3 on and Scream OD in DST. These are starting points rather than Valeton's numbers. If it fizzes, lower Gain first and Treble second.
What firmware is the Valeton GP-150 on?
Valeton's English manual covers firmware V1.0.5, and its product page lists V1.0.5 and V1.1.1 to download, marking V1.1.1 as compatible with version 2.1.0 of the computer and mobile software. Firmware updates go in through Valeton Suite; About in the global settings shows the version you have.
How do you build a patch on the Valeton GP-150?
Pick the amp model first, then set its controls, then add the blocks in signal-chain order: drive before the amp, time and modulation after it. A patch built the other way around ends up compensating for the wrong stage. Tonelify returns the model, the order and the parameters together.
Does Tonelify support the Valeton GP-150?
Yes. Name it in the tone matcher along with the song you are chasing and the settings come back adapted to it. Gear does not need to be in the catalog for a match to run.
