The RG3620Z's acoustic tone is warm and clear with decent
natural sustain and even string-to-string balance. Immediately after
plugging in, it’s obvious how versatile this guitar can be. Some
rock-oriented guitars can sound a little dark through vintage amps, but
these humbuckers are clear and defined with no trace of edginess.
They’ll effortlessly push a tube amp into overdrive for raunchy 'brown'
rhythm and lead tones, and they clean up a treat thanks to a treble
bypass cap over the volume pot.
The split coil options are extremely well-chosen. The two inner coils combine to nail that phasey scooped-mid funk thing, while the neck coils in parallel are a touch more full-bodied – like a Strat set on neck/middle, but a bit less phasey.
High gain really brings out the true voices of these pickups. The bridge is more aggressive, producing big power chords, tight low-string riffs and pinched harmonics with squealing ease. The neck has a mellower vibe, yet it’s clear with no mushiness. They're complementary rather than contrasting, and both are very responsive to touch dynamics.
