This pedal started out as a soldering practice kit that I’ve expanded into a full fledged pedal because it sounds so darned good. It is mainly a clean boost and it adds some brightness and fuller tone as well, and maybe a bit of an edge. Of course the more you push the signal into your amp the more the amp will distort at the same level. But overall it lets you solo at a higher level without adding appreciable distortion. You can also set the volume so it will play at a lower volume as well, useful if you play as poorly as I do. Think of all the effort you'll save by not having to reach down to your volume pot.
