Mods for 2 channel 20w JCA amps

Note: For a JCA 22H and Custom 22, you can install only one channel re-voice mod per channel (Overdrive and Crunch/Clean), but for the most part, you can install as many auxiliary mods as desired. If you are un-sure or have any questions, feel free to reach out at info@epic-tone.com
