Public service announcement for guitarists: Make sure you use the correct power supply for your pedals. Somebody used the incorrect power supply on this Boss DS-1. The protection diode completely blew out, got hot enough to melt the solder, and blew out 2 of the filter capacitors. This can even be a fire hazard in some cases.
If you’re not sure which power supply to use, look it up. Most pedals (~95%) use a 9 volt DC center negative power supply, but some require a different type. Refer to the owner’s manual, it will tell you which type of power supply your pedal needs.
You can also send me a message and I’ll be happy to tell you what you need to power your gear. Manufacturer warranties usually won’t cover damage due to using the wrong power supply, and it’s very easy for them to tell if that’s what caused the damage.
If you’ve accidentally done this and your pedal isn’t working, I’ll be happy to take a look and give you a free estimate to get it working again. If you’re lucky and the damage isn’t too severe, the cost to repair is minimal.
