A drunk Bavarian 

Buzzwords and phases are thrown around the pedal industry more than ever before and Power Amp Distortion sure fits into that category. The Grantler by Red Sun FX is just that, but what does that mean? Put simply, normally amp overdrive comes from the pre-amp with much smaller Valves/Tubes and much easier to create driven sounds with. The power amp section of an amp turns up the volume so we can all hear it. 


It is possible to push the massive power-amp Valves/Tubes so hard that they will clip (create overdriven tones). The result is a monstrous deep throaty roar normally unobtainable by any other means. Except …That’s exactly what Red Sun fx have created here. The name Grantler means a loud pub drunk in Bavarian which is perfectly fitting. The unique design incorporates a 1w power amp to cleverly replicate the tone and you decide how much beer to feed the monster. If you’re looking for a driven tone thats different and still versatile then your looking in the right place here!
