Hello everybody, we are going to start soon tracking our debut album. This is a self-produced album, and the keyboards player just told us that for guitars and bass we should strictly use the same gear for all the tracks, meaning if I use my Spector active bass on a track I cannot use fender precision on another as the bass and the guitars should have the same timbre all throughout. The same goes for amps. we can use different pickups configurations or EQing. How true is that?
