This page is dedicated to our Bass conversions for the Boss DS-1. These pedals are cheap, plentiful, and reliable which makes them a great base for modifications. Our Standard Bass Mod starts off by increasing the bass response throughout the pedal. The distortion is changed to be less compressed and the tone section is modified to better suit the bass guitar’s lower frequency. The Deluxe Bass Mod takes this mod one step further by adding a toggle switch and bass shape knob. The toggle switch allows you to select more compression than the Standard Mod. The bass shape knob shifts the lower midrange response and works in conjunction with the tone knob. The Standard Bass Mod is set to our favorite setting; the Deluxe Bass Mod is recommended for those who want to experiment with their gear.
