Alright, having spent a long time GASing over pedals and being completely incapable of picking which ones I want, I've decided to go for a nice multi-FX. I'm thinking in the $500 range. Some of the effects I've been looking at separately are distortion, octaver, synth, and wah, so a pedal with those and more would be amazing. Given my desire to wah it up, and expression pedal would be nice, but I'd be willing to forsake it if there was another model with better distortion, octaver, and synth. Tl;dr: What's a good Multi-FX Pedal in the $500 range?
