Good little digital emulator and additional distortion pedal. I use this for really small gigs when my Blues Jr. is too much. Great at low volumes with my '58 Gibson ES-125. I've even used it playing a blues festival when my lead guitar player's amp went out and he had to use mine. (Other bands were complimenting me on my tone. Go figure.)
This is one of my workhorse pedals. Not gonna blow your mind, but works every time.
