Modification Descriptions:

Buffer Retrofit Stop your volume pedal from destroying your tone! The Griffin Effects Buffer Retrofit adds and input and ouput buffer to the pedal. This does two things. It isolates the pickups to prevent loading of the volume pot and removes the series resistance of the pot combining with the capacitance to ground of the guitar cable. The tone that goes in is the tone that comes out!

You can also choose to have a DC jack, DC extension, or both installed.  

Now includes an LED on the circuit board to light up the inside of your pedal. There is also a switch to turn the LED on/off.
Choose the color of the LED from the color picker above.

This kit is for the passive volume pedals. After installation, your pedal will be an active pedal and require a standard 2.1 center negative power supply (not included). The volume pedals circuit board will be replaced with a new one. This new circuit board will have a  DC jack on it. To make plugging a power supply in a lot easier, we suggest our DC cable extention.

Some volume pedals have a taper switch or pot. Installing this retrofit will remove this function as you will no longer need it. This retrofit will not work on stereo pedals.

This kit has been sucessfully installed on these following VPJR versions:
