Description

Step up your overdrive game with the Keeley Boss SD-1 Super Overdrive Ge 5 Star w/Diode Switch Mod. This pedal is a versatile powerhouse, bridging the gap between smooth blues tones and the gritty crunch of full-on distortion. With Keeley’s renowned craftsmanship, this modded pedal transforms the classic SD-1 into a hard rocker's dream, injecting a new level of dynamism into your sound.

The magic lies in its upgraded internals, where every component is meticulously enhanced for superior tone quality. The standout feature is the addition of a toggle switch that introduces a germanium diode into the clipping circuit, offering a unique blend of harder drive and increased compression. This allows you to tailor your sound, reaching new levels of sonic depth whether you're riffing through blues or cranking up for a rock anthem.

Moreover, the mod includes true bypass switching, ensuring your signal remains pure and uncolored when the pedal is not engaged. This pedal is perfect for guitarists seeking a multifaceted overdrive that can effortlessly switch from subtle warmth to a more aggressive edge.

Key Features:

  • Germanium diode toggle switch for versatile clipping options
  • Enhanced components for improved sound quality
  • True bypass switching for unaltered signal integrity
  • Range of tones from smooth overdrive to near-distortion levels

Best Boss SD-1 Out There!

Great mod to have on your Boss SD-1! This was always on my pedalboard until I got my TubeScreamer modded by Keeley. Still a great pedal to have!

Almost always on

I love this little beauty. It's hardly ever in the top switch position ie: always flicked down. I normally have it set at 10o'clock, 2o'clock and 2o'clock.
