Easily add gain to your Plexi, Marshall, or Marshall-style amp! Tones like Van Halen, Dokken, Motley Crue, Whitesnake, etc. can be dialed in with the X-Gain modification. Our X-Gain Modification is the same X-Gain mod we offer with our M50 Plexi (stock) and M100 SuperPlexi (add-on) amps. It is a switchable mod (via Push-Pull pot) that increases the gain/overdrive in most 1987 (JTM45/JMP50/1987x/50 watt), 1959 (Superlead/100 watt) circuits, or any Plexi/British style amp that has Bright and Normal channels. No chassis modifications are necessary, and no solid state components are used. Your signal path remains “all tube.”

DISCLAIMER: User assumes all risks. Performing these modifications will most likely void the warranty on your amplifier. Working on amps can be deadly if you do not take proper precautions. Read and follow the diagram or instructions very carefully. Basic soldering skills and basic user-supplied tools are required. If you are at all unsure of your ability to perform these modifications STOP and take your amp to a professional to be modified. You can also send your amp to us for modification. Contact us for pricing.
