Description

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.

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

Better than original TS9

I have a Keely Mod Plus TS9. 1. There is really less noise than in original one. When you turn on several dirty pedals - it has more noise. So Keely mod is better to use with other dirty pedals. 2. Bass exists! I see it still cut bass a bit - but now you can play riffs with Keeley Mod 3. Drive range is from transparent to a lot of gain =) And all these options with these big amount of mid range as original TS9 has.

So I really recommend this variant as more musical due to original TS9.

This is always in my pedalboard

Perfect boost pedal to drive the tubes to give you great sustain for leads, and boosts mids to help cut through the mix. The Keeley mod makes it smooth and gives the real vintage tones of an old 808

Exploring diverse overdrive and distortion sounds

Ended up doing the exact opposite of what I said. Now I'm using the Keeley TS9, J&H, and the Hardwire distortion. Sounds good to me and now I have 4 different OD/ distortions to play around with.

May I ask why? I've always been curious about the Keeleys.

eryeager

It's a great pedal. But honestly that 40 dollar danelectro drive pedal can do anything this can plus more. It is essentially a very expensive boost for my purposes.

T

great boost

great as a blues overdrive or to push a crunchy amp into high gain

I hooked up with Robert Keeley because of the work he did. I had a Tube Screamer that he modded for me, which is obviously how he got to be known, by modding the original pedals... and then, we've just been good friends ever since and, in the end he loved Framptone stuff and it worked so well with testing out his stuff through two different amps and it was sorta, like, a good fit. So, we just, virtually said "Well, why don't you take it over? We'll call it Framptone by Keeley."

"I used a TS-9 with a Keeley mod and that was actually Brandon's who produced the album – he brought a whole suitcase of pedals for us to play with. I had a Fulldrive 2 before that and wasn't totally happy with it but that TS-9 has some sparkle to it and all the notes ring out in a unique way. Different to a stock TS-9 for sure. That was for a milder distortion…"

"I’ve been using a GigRig Pro 14 for a few years now. It’s a great switching system that allows me to have all of my pedals in front of me but I can have patches set for certain effect combinations so I only have to hit one switch. It also allows you also turn things on and off individually. It’s all true bypass so I don’t lose any tone. The pedals on the board at the moment are an RC Booster, Providence Compressor, Keeley Mod Tube Screamer, Eternity Love Pedal, Fulltone Octafuzz, MoonPhase (phaser), Arion SCH1 (chorus), Demeter Trem, Eventide Time Factor, McCoy Wah, and a GigRig Wet Box which allows me to use both sides of the Eventide Delay pedal. One side is set for my normal delays and the other side is set so that I can have Dub style delays which I can call up just by hitting a switch on and off on the GigRig Pro 14 leaving the delay trails carrying on while I’m playing another part. I switch things round every so often, always looking for new overdrives etc. I have a Providence SOV-2 which I love."
