Product Description ● This is a 2-in-1 effects pedal based on the Tube Screamer TS-9, with modified gain settings, a booster, and added switches. ● This effects pedal is an improved version of the TS-9. The DRIVE pot has a higher value than the TS-9, so it distorts more when fully driven. Conversely, the boost when the drive is set to zero is gentler and more natural than the TS-9. ● The "VINTAGE" switch allows you to change the tone to a more vintage sound. ● The "MODE" switch allows you to select between the normal TS mode (down), a mode that distorts the sound more coarsely like a LANDGRAFF DOD and increases the volume with LED clipping (up), and a Dumble mode with less distortion (middle). ● The booster lifts the overall sound without distorting your favorite sound created with the TS. You can use it for solos, etc., so you can cover many roles with this one pedal. ● The op-amp is socketed, so you can easily replace it yourself. The included op-amp is JRC4558DD. ● The guitar side is TS SRV and the amp side is the booster. ● EBK is a name used only for auctions. In the original business, we adjust, create, and adjust guitar equipment such as amplifiers and effects pedals specializing in blues-related equipment.
