The legendary Tube Screamer taken to the edge of tonal Nirvana!

The original Ibanez Tube Screamer made history, and Keeley's TS9 Mod Plus will have you making tonal history of your own. Used by guitarists including The Edge (U2), Peter Frampton, Jon Herrington (Steely Dan), and Larry Crane (John Mellencamp band), the TS9 Mod Plus has a number of enhancements over the original that give it a sound closer to the Ibanez TS808 Tube Screamer.

Keeley Effects use the Texas Instruments RC4558P chip, just like early Ibanez TS808 Tube Screamers. Additional mods include replacing the carbon-composite output resistors with metal-film types that don't introduce noise to the signal and increasing the bass response for full low-end richness, and increasing the overdrive range. The result is a cleaner sound when turned down, twice the gain and drive when cranked, and stock TS808 sounds in between. The bypass circuitry was also improved, as well as the tone control circuit.

mod plus

Had the stock ts9 then got it modded to this spec.Wow! No bass loss, excellent as a clean boost, built like a tank and sounds super warm and creamy with an amps overdrive channel.Great w/ Mesa mark iv for killer tube dynamics! Don't let people fool you either; it still has warmth through a solid state amp. Buy It!!!

Much Better

I have a stock Ibanez TS-9 and I never understood why people like it so much. I stumbled upon the Robert Keeley website while looking for modded pedals and I read the description to this pedal and decided to get it. Wow the bass response is better and not cut off. It is much cleaner and also has more gain than the stock TS-9 and with less noise. I hate the hissing my other pedal produces. Heck mine even sounds better off because of the true bypass. If you didnt like your ts-9 and you still have it just send it to keeley for a few extra bucks and who knows you may like it afterwards.
