Modification Descriptions:

Rock Hard - We have eliminated all the treble buzz and what's left is a great distortion! We have been tweaking with the DS-1 for many years trying to make is sound better. We stray from the normal modding avenues and try something a little different. The result is the DS-1 Rock Hard. We've taken the 80's metal out of the pedal and made it a sweet tone machine. Fat sound, well controlled top end, a good midrange and no more fizzy distortion. We've also moved away from using LED's for clipping with this mod and use transistors instead. The result is an amazing sounding pedal with a '70's hard rock edge.

Rock Hard Samples:

Rock Hard Demo 1 

Silent Step - Get the Griffin Effects Silent Step soft touch true bypass installed. The Silent Step uses the stock Boss switch so it will maintain the stock look of the pedal. There won't be a big switch sticking out the top!!!

To send your pedal in for modification, print and fill out this Modification Form and send it in along with your pedal. All the information you need will be on the form.
