A solid preamp/distortion. It’s two pedals in one, a tube-esque preamp and a percolator fuzz. Both the pre and the perc can be turned on independently of the other. The fuzz feeds into the preamp and can act as a boost or a super articulate fuzz. It’s crazy versatile and works with any amp. Ive used it with my twin/musicman but i’ve also recorded with the perc driving a jcm into dino jr territory.
This pedal is discontinued and is selling for stupidly high prices on reverb. You probably wont find it for cheaper anytime soon.
