Welcome to Granger Amplification. We manufacture high performance vacuum tube amplifiers.



Granger PRC30 valve amplifier

One word - CLEAN! The Granger PRC30 valve amplifier is our nod to the classic Princeton circuit, but with a beefier power supply, tightened but full bass response, and all the lush clean tone you need for any small to medium sized venue. The PRC30 features a 2x10 combo cabinet, with two WGS Veteran 20 10" speakers. Ouput is 30 watts from a pair of JJ 6L6GC. Preamp compliment of (3) JJ ECC83S (12AX7) and (1) JJ ECC81 (12AT7). The controls are straightforward - Volume, Treble, Bass, Reverb, Speed, and Intensity. Although we focused on the clean output of this amp, it still growls at higher settings. The PRC30 is also a fantastic platform for your pedalboard, whether running distortion, overdrive, or modulation/time-based effects. The reverb is spring tank - full and lush. The Vibrato functions just like the original. We have tweaked the circuit the way we generally do, because if a circuit can be improved, we do it!

Custom options include tolex & grillcloth changes, and a custom cover with Granger logo.
