The Griffin Effects Buffer Retrofit adds and input and 2 output buffers (one on the output and one on the tuner output) 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!
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 one will have a DC jack (no drilling required) on it which can be accessed from between the treadle and the base of the pedal.
The Griffin Effects Buffer Retrofit kit comes without jacks. You can remove the jacks from your existing board and use them or get new jacks found here: Part # E14JACKM
The buffer comes with a DC jack installed. A DC cable extension is available to make plugging a power supply in a lot easier if you plug and unplug it often. The DC jack can also be removed and placed externally in the pedals enclosure if you wish to drill a hole.
Some volume pedals have a taper switch or pot. Installing this retrofit will remove this function. This retrofit will not work on stereo pedals. Soon a retrofit will be made that incorporates these functions.
This kit has been sucessfully installed on these following VPJR versions:
