Description

The TS9DX FLEXI 4x2 starts with the same chip used in both of Robert Keeley's other modded Tube Screamers (the Baked Mod and Mod Plus): a Texas Instruments RC4558 chip, as used in original TS808 Tube Screamers. Metal film resistors are used for low-noise operation, while stacked metal film capacitors and increased input impedance deliver a crisper, more lively tone that's incredibly transparent.

The TS9DX FLEXI 4x2 Tube Screamer mods don't stop there, however. in addition to standard Drive, Level, and Tone knobs, it has a four-way rotary "Turbo" knob for different overdriven tones on the fly. Combine that with the 2-way gain switch and you've got eight tube-amp like tones at your disposal.

The most advanced modded Tube Screamer!

A solid upgrade

Highly recommend getting your hands on one these if your a fan of the OG TS. Nice little mod adds serious substance and it's super quiet.

Steve's setup: "The guitar in line goes into the Wah Wah on the board - either the Dunlop automatic one or the Bad Horsie (he switches between the two). From there it goes to the two distortion boxes, the DS-1 and the Keely modded TS-10, then the EvH flanger and from there it goes back into the front of the amp.

Note the error: He says TS-10 but as one can see in the photos here:
