Rehousing boss DD7

[Bradleymiles]

So I'm attempting to rehouse a boss DD7. Putting it into a larger enclosure with 2 momentary switches. One for on/off and one for tap tempo. Also the DC jack and the 4 pots and the led are mounted directly to the pcb. So I desoldered the pots, DC jack and the led to remove them. Reason being is for relocation. I want the pots spread out further so I pulled them off the board, added some wire in to spread them out. I did the same thing with the DC jack but the factory jack had 5 pins when the new one only has 3. Not sure where to connect them to. I did my best, getting very low voltage to the led. Not coming on. Any suggestions? I feel like the problem is how I'm hooking up my dc jack. Any suggestions would be greatly appreciated.

If you still have the old DC jack, place the power cable in it and feed it power. Use your multimeter to identify what tabs are getting power, ground, or unused if any. Then relate those tabs to where it sat on the PCB and connect your new power jack accordingly.

Thank you. I wouldn't have thought of that.

No problem! Might take a few probings to get two that match up, but once you get a positive voltage reading, you can just leave the ground one and poke the rest. Hope it works out!

Thanks I got that worked out! Power is good!

So now I've got the board all soldered back together. I tried testing it before putting it back into its new enclosure, nothing but noise, loads of static. No sound from guitar. How do I troubleshoot this? The led only comes on if I short it my holding both pins with my finger. But no sound passing through

How easily did you desolder the pots and whatnot? In my experience these things are a huge pain in the ass to get out and end up in lifted or destroyed traces. Make sure things are all still connected. Besides that, if you can get a schematic it would be helpful, but I'd imagine it looks like a mini computer in there.

It was actually fairly easy to desolder. I have an iron specifically for desoldering. It sucks up the solder as it melts. Everything came of the board in one piece. I was very careful throughout the entire process. Only messing with the few components I was moving. It's all put back together now, but I got nothing. I haven't found a schematic for it, but it does look like a mini computer. The board is pretty insane looking. It's not quite sure where to go from here I guess
