First let me say this is a total keeper for me. Second, let me say it didn't start off that way. When I first got the pedal, the only amp I had available was a small guitar amp. I knew I wouldn't get great results but what concerned me the most was how noisy it was and a slight buzz/distortion without even pushing the gain much. I told myself to keep the box since it was likely going back. On the other hand I could tell that it fattened up the sound a good amount so I figured I would sleep on it and decide after using it in a real sound system. Fast forward to Friday night church practice with a real sound system. Whole different story! First of all the pedal is absolutely quiet and let me tell you - we have a lot of buzzing/white noise problems with that system. Single coil pickups, vintage amps and the like wreak havoc. Not this pedal -totally quiet. NEXT: The added beef this thing adds to the signal is just right. Not over the top but it's there and it's real good. Best of all is the gain control and the compression. The gain can easily give you a full, saturated sound (that I like) and a WIDE range of compression. Personally I like the "squish" setting with the gain at 3:00 and the compression at 3:00. This gives a full, fat tone with lots of sustain - AWESOME! We have some amazing musicians on our praise team and they agreed that this thing is righteous. The one praise band leader literally said "that thing solves all your problems" - the problems being some notes weak, some boomy and not enough sustain. All notes are full and fat and keep ringing out. Tone is better than ever. On top of all that, even though this is a big pedal it still fits in my bass case so I just need to lug one thing to practice and to church! I highly recommend it.
