Boss EV-30

I use Boss EV-30 with Boss MS-3 as volume pedal and as a wah pedal. Works great and has a lots of options. In size vice very good. One possible (not 100% sure yet) downside is that, as a volume pedal use, there might be a certain spot where volume doesn't go up/down perfectly smooth, meaning there's is a "step". This might be also just an adjustment issue or using EV-30 at very low amp volume, not 100 % sure. Anyways, not a deal breaker. In general I'm very pleased with pedal. Ordering and delivery was smooth and quick by Thomann!

Maybe just this one was faulty but the tracking is off and it won't go back to 0, sometimes 1, 2 or even 3 (out of 100)
This doesn't matter on wah effects or volume, but pitch effects are ruined.
