Anyone blow up Fulltone Fulldrive 2??

Post by jem »

Just got a Fulltone Fulldrive 2 and I already blew it up :oops: :twisted:

Didn't realize that the power supply cable I used was the opposite polarity of the others....

Anyway, I put in a op amp socket to swap 4558's and that's not it. (Major pain in the rear, those boards are not created to be repaired.


Anyway, if anyone knows what normally blows in these, I'd appreciate it. No shorted diodes that I could find from a quick check.

Its a common thing to have happen. The company is hard to deal with too.
It is after all your own damn fault. It not the chip or transistors or diodes.
I was given a blown one and went that far. I think its the resistors. They are
1/8 watt, when I get back around to it I was gonna try some freeze spray
to try and ID which. There are some good scheme and layouts out on the
web. And yes, they are a major P.I.A. to dis-ass-emble.

Attached is a pic/schematic that may be representative of your pedal. If so, check the diode in parallel with the filter cap, it may have shorted first and saved the rest.

Yeah I learned that lesson a while back with my Xtreme pedal it uses AC not DC so I didn't hurt it applying DC current, thankfully. Went out to find an AC wall wart for it the old one died years later. Of course I got the stupid deer in the headlight look :shock: They said well they all plug into the AC outlet! :roll:

Then I had to explain I know that dummy but I need one that steps down to 9 volts AC not DC thank you very much. Found one at radio shack and the smart thing they did was made it in white color rather than black so I always know which one belongs where. Got luck with your fulltone.

If that schematic is correct replace C1 and D3, chances should have been that you toasted the supply not the diode, Did you try with a battery?

Hooking up the wrong polarity of DC will always toast that incoming didoe,..that's one reason they put it in line.
