Modification Descriptions:

Improved Vibrato - There is one flaw with the vibrato mod most people/companies do...they simply add a switch to cut the dry signal create the vibrato effect. This means you have to flip the switch back to chorus to make the pedal bypass properly. What a pain and not really ideal. We address this issue and created a little circuit that takes care of this issue. With the Improved Vibrato mod, the pedal will bypass properly no matter if you are in chorus or vibrato mode! 
We also make the LED blink along with the rate of the pedal!

This mod will work on all revisions (both SMT and through-hole) of the CH-1 and can be installed in a new pedal.

Disclaimer: The Improved Vibrato mod requires drilling a hole for the switch in the pedal.


If you choose to have the mod installed in your pedal you send in, after purchase you will receive a email with the information you need to send your pedal in.

So much better

I had a switch in there done by someone else and didn't like how it worked. Griffin Effects mod is much better. I don't have to worry about swtiching it off before I bypass the pedal
