Keeley Mods


Check out these tones! In collaboration between Mammoth Electronics and one of the giants of the guitar effect pedal industry, Robert Keeley, we are proud to announce the return of the Robert Keeley mods. The Keeley mods, originally done by Keeley Electronics, will now be offered exclusively by Mammoth Electronics. All of the classic Keeley mod sounds you know and love, built by some of the very people who used to build them in the first place. From the smooth midrange overdrive of the TS-9 Mod Plus to all of the metal you can handle via the MT-2 Twilight Zone, these are the classic tones shaped by Robert Keeley himself. You can but these new from the site or send in your own pedal to get the mod done. Get these Keeley pedal mods now!
