In a time long ago, 2001 to be exact, Keeley’s mods for the TS9 Tube Screamer became pretty legendary. They set the standard for a complete set of changes, a dozen in fact, that took any screamer to the next level. Those mods included an increased bass response, a fine-tuned tone control, greater cleans when turned down, and much higher gain when needed. The Keeley Mod Plus was born.
In fact the mod was crafted so well that it didn’t change one bit in nearly 14 years. The circuit and mods have been on some incredible stages, Steve Vai, Joe Satriani, Brad Paisley, John Petrucci, heck who hasn’t toured with a Keeley TS Mod in the 2000’s?!?!
The Red Dirt came out in 2012 and is currently on tour with John Petrucci and Devin Townsend to name just a few. It is essentially all of the Keeley mods wrapped into one pedal. It also features one really important addition, the JFET input buffer. A mod that couldn’t be done to the old screamers is a JFET input buffer change. Now the Red Dirt and Red Dirt Mini are more open and dynamic… and let your pickups breathe in a way that you’ve not heard.
