i just recently downsized from a 3 channel amp (mark IV) to a 2 channel (budda SD18). i'm still not bold enough for just one channel! *there are 3 categories in this poll and you can vote for all 3* how do you use your channels? do you have master volume? do you use the FX loop? what kind of gain pedals do you use to expand your options? what's in your FX loop?
