I'm looking for a new amp. I basically need a good pedal platform with a nice clean sound at gigging volume. I was looking at the Orange pedal baby 100 because they say it was designed for guitar players who depend on their pedalboard for their sound. But it doesn't mention anywhere if this means there should also need to be a preamp in front of it. How does it sound when all my pedals are bypassed? Does it need a preamp for clean sounds?
