Here's a nifty, long discontinued pedal/preamp that works very well as an overdrive and/or amp simulator as well as a preamp for practices or jams. Besides, anything with Jerry Donahue's signature must sound good, right? This certainly does!
After many years of use, this unit needed some internal cleaning. Although very ruggedly constructed, just four small screws needed to be removed to access the pots and switches for servicing. A smart design, and a relief not to have to dismantle the entire assembly as you must with most other pedals.
Some contact cleaner and working the pots back & forth did the trick. As usual, the input and output pots were particularly sticky and needed a little extra persuasion!
The switch was quite gummed-up too. Didn't take long to have this back in business again and working like new!
