Choose your modifications from the drop-down menus then choose a new pedal or your pedal.
No.1 - Adds some bass. It also makes the distortion less fuzzy and more dynamic with a better tone. More output volume.
Silent Step - Get the Griffin Effects Silent Step soft touch true bypass installed. No more switch popping! The Silent Step will need to be installed in the battery compartment on some revisions of this pedal.
True Bypass - Latching 3pdt true bypass for older pedals that don't have true bypass. If you need help identifying if yours is true bypass or not, contact us.
These mods can be installed on any revision Distortion+.
