I have recently acquired a Laney CUB12R which is an inexpensive (in relative terms) single channel tube (valve) amp. It sounds great with my SG both clean and OD (in my low standards). Since it is a single channel and there is no switch to quickly change from clean to OD, I am thinking of adding a OD pedal (or use my Line 6 Amplifi FX100) in front of the amp. Are there any other suggestions on achieving what I want to do? How do you use your single channel amps? Cheers in advanced.
