I've been using this pedal for a while now, and it is very good, once you read the manual and get used to setting the parameters. One thing I've not mastered yet is the pedal synth. I'm trying to use the bass guitar with a clean sound and the bass synth pedals at the same time. Problem is they both affect each other. The pedals sound good, but the bass plays with a synth effect. Does anyone know how to bypass the effects for the guitar input, but still use the bass pedal effect?
