This is excellent booster that you could use in many different ways. I use it with my Orange Rockerverb III as I mostly stay on dirty channel and it allows me to have a few different stages of gain. With Oranges, it works better than any overdrive I tried. If you put it in front of the clean amp or in the loop, it will give you less gain and more loudness. It has five responsive controls that allow me to really shape my sound and I think it can adapt to any amplifier. It does not color the sound too much.
Only negatives are minor: knob in the center (Gain 2) is tiny and is placed among much bigger knobs and it is hard to reach and set precisely. Pedal is beautiful, but very shiny and sometimes it is difficult to read the labels on it.
