What amp settings do you need for The Beatles?
It depends on the song. On a generic five-knob amp, While My Guitar Gently Weeps starts at Gain 5.5, Bass 5, Middle 7, Treble 6, Presence 5, Reverb 2; Hey Bulldog starts at Gain 6, Bass 6, Middle 6, Treble 5, Presence 5, Reverb 3. These are starting points, not the settings used on the records.
What gear did The Beatles use on these songs?
While My Guitar Gently Weeps: Lucy, a 1957 Gibson Les Paul (Eric Clapton); Not documented (the Beatles' studio amps, per Ken Scott). Hey Bulldog: 1964 Gibson SG Standard; Vox Conqueror, solid-state, with its built-in fuzz. Each song page lists the sources behind its rig.
Can you get the The Beatles tone without the original gear?
Yes. What carries these sounds is the gain structure, the EQ curve, the pickup position and the order of the effects, and all four can be rebuilt on other equipment. Tonelify rewrites each starting point for the amp and guitar you own.
