Tested with both a 9V and AC adapter. The buyer may need to adjust the internal trim pot. All electrolytic capacitors have been replaced mid-2025. The SPECTRUM potentiometer has been replaced with a long shaft pot. The original O-ring melted onto the pedal and was removed as best as possible (pictures 19 and 20) to allow for a replacement.

Unfortunately, I do not accept returns under any circumstance. Although the unit has been tested, please assume that the worst is possible such as the unit does not work, as a component could go bad between shipping and when it reaches the buyer's hands. Although I've yet to encounter such an experience, in the event anything occurs during shipping, I do not accept returns under any circumstances, so please consider this before making a purchase, especially considering the cost of this unit.
