I've had the pedal for a few months now, and I just can't dial it to where I want it. It will produce a lot of great sounds,but some of them are just unusable. Maybe its my other gear, but other pedals work fine? I'm using an SR506, into a Jeff Berlin combo. Any recommended settings for my guitar or amp to get this pedal hitting a nice auto-wah that isn't "pingy, or super low and bubbly?
