I've had my eye on it for a while, found a deal, and pounced. I spent around two hours last night futzing around with the settings using the online guide, and WOW this thing is fun. I've been faking my synth sounds using a MXR Bass Octave Deluxe --> Fuzz (previously MXR bass fuzz, then EBS multidrive, then Mastotron) --> Chorus, but this blows them all away simply because of the sustain functions. I posted a question about getting the pedals needed to nail the synth part on an Outkast song a while ago, and with this pedal into my MXR Bass Chorus Deluxe, I've done it! I may post some sound clips later. My next question for those who have the MicroSynth, or for any opinionated people on TB (if only I could find one...) is will it be necessary or needlessly redundant to keep the mastotron and octave pedal now that the MicroSynth lives on my board? So many questions!
