The TSVG Hard Stuff Bass is designed as a pre-amp bass boost pedal. Use it to add transparent boost to your low end signal while also adding some growl through the mid-range. Turn up the boost knob and push your tube amp into speaker pumping, low end punchy overdrive. The TSVG Hard Stuff Bass is not a distortion pedal, so it will not distort your signal. It will, however, do a wonderful job of pushing your tubes into overdrive or boosting your clean signal without any coloration. This is a perfect “always on” pedal. The TSVG Hard Stuff Bass is built by hand in Philadelphia, PA with hand-picked and matched components.
