I just sold a good working dig. delay. Soon after I got a text. He was not happy-thought I sold him a lemmon. He called back and said he thought he my have messed it up. Said he connected it to a 18 volt power supply. It takes a 9volt. Would that do it? What would it take to fix it? Thx, Ron

Hey Ron, yes, plugging 18 volts into a 9 volt pedal can certainly do damage. I looked at the schematic for the Boss DD-5, and it doesn't have any internal protection against over-voltage power like 18V. If it's not working, then something was certainly damaged, you can't know until you open it up and start testing. Could just be one part or could be several, and everything inside is surface mount components, which take more skill to remove/replace. He may be able to sell it as "not working" on eBay or Reverb and get a few dollars for it.

| Yes, he unwittingly fried it. I used to work at a music store many moons ago and have seen the damage careless power supply selection can cause. I doubt it’s worth trying to repair. |

Such a shame, when 20 cents worth of parts put in by the manufacturer would have eliminated this problem.

Agreed. I make effects pedals, and I've always protected them from user errors like this. Only takes a diode or two and a resettable fuse. Some manufacturers go the extra mile, Lehle not only protects their stuff from wrong or reversed voltages, but it will run happily on whatever power you put in. More costly, less efficient use of power, but they don't get returns for repair.

Planned obsolescence, m'boy. Just like Ford or a Chevy. If they built 'em to last forever, nobody would ever buy a new one. |
