So I've currently got on my board a compressor/sustainer, a cab sim, a delay, and a looper. My power supply supports five pedals, so Obviously that means I need another pedal to complete the set up! I play mainly 60s/70s blues, rock, etc and also this is into headphones/DI as I don't have/want an amplifier (hence the cab sim). So what would people suggest? An EQ? Reverb? Something else?
