I got this pedal mostly to permanently boost a vintage strat with weak pickups, since i couldnt get my amp working just right without a little more input volume. I was gonna leave it on all the time, when playing that strat. However, when playing other guitars through the same pedalboard/setup i started using it as a solo boost, to kick the preamp a bit harder. The sound is quite transparent, allthough i think there´s a little midboost as well. It is very sturdy, and will not break easily. Have not run it on a battery so i am not sure about battery lifespans. All in all a good product. Have been gigging with mine for a year now, and no problems yet. I would not hesitate to get another if i lost it, or it got stolen. It could be a bit smaller.
