I have a Roland AC60 which is great for my acoustic guitars with pickups (country stuff) and works well with my ES175 copy if I do jazzy stuff. Supposing I want to do some rockabilly stuff on the electric, how should I set the amp knobs? I realise the sound is subjective, but generally, do I want full bass or full treble or full middle, or half way or zero.... I like to keep the chorus on for jazzy stuff, how about for general rockabilly? Should I use reverb instead?
