I have tried a lot of boost and drive pedals, and I like a nice compressed sound, but I have never had luck using compressors. After reading that Pete Townshend uses an MXR booster for end of song rave ups (his term), I thought, I need to try this. I love it- it is very versatile. You can use it as a relatively clean boost with mild compression or really get a clean sustain. Works well after a distortion (like the Apocalypse by DBA) to boost for solos or just for more sustain. I also have a Katana Clean boost running into the MXR. The two work well together - using either the MXR as a base tone then driving it a bit w the Katana for leads, or using the Katana as a base then boosting and compressing a bit for leads. Money well spent.
