I replaced my jcm800 with a fargen olde 800. I have the same scenario as you describe. I set it for a touch of gain. I use a bumbox bust for the clean boost tones, solos, etc. The times I want the amps sound, but louder. I use a jekyll and hyde for my distortion tones. It's nice, but does color the sound. I am after a pedal that will give me the almost mesa saturation, but less tonal coloration than the jeykll and hyde. I did not like my crunch box into an overdriven amp.
