I offered these things as a service in the past. I have recently added a couple of tutorial pages that show how you can do these mods yourself. They're really pretty simple mods to do, but a bit labor intensive. The biggest pain about them is taking it apart to do the mod(s), which is an awkward affair.

Repairs and Reconditioning


I have also repaired several non-functional units that ranged from malfunctioning to completely dead. Troubleshooting can be somewhat time consuming due to the complexity of the circuitry, so please Contact Me with a description of your problem and I can give you an idea of the costs involved to fix your ailing ADA Flanger. While I have it in my shop, I will go thru it and do any preventative maintanence that really should be done and clean it up for you, too. When it's done, it should last another twenty years!





From Tony Stephens Illinois, USA 1-11-09:

Regarding ADA Flanger Repair

"VERY COOL! Thanks for your efforts, Paul! It still blows me away--the
folks "out there" that are into various facets of this thing we call
guitar--and are willing to do the type of work you do. Amazing what can be
found with a little looking on the ol' internet. I don't know what would
have happened with the pedal had you not taken on the task of fixing her up.
Thanks so much..."

(The owner had attempted to repair the malfunctioning unit by taking apart the bypass switch, which ended up ruining the switch. The switch had to be replaced and the actual problem also needed to be fixed)
