From the vendor
Very nice blues-rock overdrive. For all those who like not too much gain, but appreciate dynamics and sensitivity to articulation. It also works well as a boost to a tube amplifier. Based on the classic version with presence control added to control the upper part of the frequency range.
PCB. Dimensions: 48 x 28mm.
