The Hot Mod V2 EVO is a plug-in dual tube module engineered to dramatically increase gain in Marshall and other amps. No chassis cutting, drilled holes or wiring modifications: it simply installs in place of the cathode follower tube (often V2).
No solid-state tricks or clipping diodes: 100% pure tube gain. Because the extra gain is created inside the amp rather than by a pedal in front of it, noise stays dramatically lower even at high gain settings – and your signal still cleans up when you roll back the guitar’s volume.
- Bass Boost/Cut switchdown for tight articulation, up for rich low-end resonance.
- 2-stage Gain switchdown for more clarity and attack (original Hot Mod V2 voicing), up for even more sustain and compression.
- 2 × 12AX7zero solid-state parts, zero clipping diodes.
- Far lower noise than a clean boost or overdrive pedal in front of the amp.
- Still takes a pedal in front if you want to push it further.
- Socket extender included.
