Until recently I never really saw the point of a "preamp pedal." To me they were just another type of overdrive pedal, and I tend to not play with much gain at all. Then with a bit of coaxing from a friend, I tried the Greer Soma '63 and fell in love with the sounds I was getting while keeping the gain knob relatively low. Basically I just use the pedal for tone shaping and a bit of bite at most. My understanding is that this pedal is modeled after the preamp section of a Fender brownface amp. When I couple it with a Fender Deluxe Reverb, I am extremely pleased with the result. I will say that the pedal has so much gain range that I find the upper end somewhat useless for the way that I play (see the video below), but I am still blown away by its range. I made a video with the pedal just for fun!
