I was recently given a 90s JTM 60 1x12 2ch combo. Pretty cool little amp,gotta say the cleans are about as nice as I've heard outta a marshall. The overdrive is Ok but the amp tends to have a boxy sound I'm assuming this is the diode clipping. Could simply swapping diode type help or is it more the circuit itself.?? All so the amp is gonna need a retube,anyone have recommendations in these JTMs?? Also what are the pre amp tubes "jobs" in this I know v4 is PI,are V1/2 gain stages and V3 tone stack and CF like others or is there a verb tube?
