Re: how to make marshall single channel amps into two channel amps
I use a weber amp switcher, between the amps and the speakers. No tone loss, no switching noise, and trailing effects are carried over.
Allows a 6l6 amp on top off an el34 amp, through the same speakers, to get base fender vs marshall type tones, versus trying to get a marshall tone from a 6l6 amp with pedals. I still use a bunch of dirt pedals because one amp is single channel, and the same pedal thru different amps produces very different end results.
It can also be set up to have one amp for clean (plus any clean boosts if wanted) and the other with some other dirt pedal, so that all that's needed is one foot switching action between the two, versus many (to turn off the clean boost and also engage the dirt pedal, etc). And a much bigger tonal jump that just swiching off a dirt pedal within the same.
