Re: DD-2/3 repair notes

Hey Laurie, thank you for your time.

Re: DD-2/3 repair notes

OK, thanks. In 20 years I've never heard a fault like this in a DD-3, so it might take some time to track down (if it is even possible to do that remotely). Let's check some basic voltages. With the pedal powered on using a battery, measure the voltage at both sides of the footswitch. One side shou...

Re: DD-2/3 repair notes

I bought it from some guy, he said that it was working before it started failing, the guy told me that suddenly started to make that.

In order to access to the schematic you ne...
