Up for sale, an Ibanez Tube Screamer TS9 Keeley Modded overdrive pedal in exceptional condition and in perfect working order. This TS9 features Keeley’s Baked mod, which has become progressively rarer since the lauded pedal manufacturer stopped selling mods.

Unlike most Tube Screamer variants which utilize the JRC4558 chip, Keeley opts for the TI RC4558P in their boutique upgrade (a less common chip seen in a handful of early TS-808s). Tonally preferred in many circles, the TI RC4558P does a great job of capturing the response and tonal color of the SRV sound.

The Baked mod boasts low noise metal film resistors and a broader bass response. The mod also increases the overdrive range, and the pedal cleans up better when the Gain is set to zero. It's a best of both worlds scenario: Cleaner when turned down and boasting twice the gain and drive when dimed, with every shade of classic 808 tonal color in between.

This particular unit is in fantastic shape, with just a scant few microscopic nicks on the sturdy green housing, retaining all Keeley foil stickers, as well as the original serialized label on the back and an additional dealer sticker on the pedal’s forward edge.
