Preamp module based on Rivera Knucklehad amp.
Unique modern rhythm tone with unusual and very effective EQ section.
We added switch for another famous model, which is called Tré, one of the baddest amps on the planet. It generates gain like an unattended nuclear reactor. Extreme gain tone but with dynamic and tightness, distortion with definition and edge.


  • Tré - activates another extreme gain mode
  • Boost another level of gain
These two features together offers 4 different combinations. All of them are very useful. From chunky rhythm with amazing tone definition to endless sustain higain tone and thunderous bottom end.

Suitable donors:
Super V, Tweed, JTM, Brahma, Plexi, Top Boost, SL+, Mr. Scary, KH-2, KH-3, 1086, Super Plexi, Modern, Ultra Lead, Ultra, Ultra XL


* All Salvation Audio preamp modules are 100% compatible with Synergy Amps, Randall RM series and old Egnater modular amps.
