To me the clean channel of an amp if really really important. Even if I play a lot in distortion, in all my own songs or the one I play, there is a clean tone part somewhere.
I never bough an amp with a bad clean, it’s a deal breaker immediately. because for many years I was using external distortion pedals on tube amp. (Until I finally found a amp with a real clean and good dist : the JP2c)
Some amps like the mark series for example didn’t take distortion fx pedals well.
The clean channel in the rectifier take very well the metal distortion pedal .
Some clean are glassy, some are deep and warm, some are a joke like the 5150
.
Yes I love playing in clean tone, that’s beautiful. Specially with fender guitars.
when you plug yourself in a real fender bassman with single coils, that’s … well.
