Effects Pedal Repairs[views:6192][posts:20]_____________________________________________ [Dec 5,2010 10:06am - MarkFuckingRichards ""] I'm in search of someone that can fix a Moog Low Pass Filter; not sure what's wrong since I suck at diagnosing but I'm guessing it's the 9v adapter jack since it doesn't power on at all. Anyone or any shops in/near Boston that could tackle this? |
| ________________________________________ [Dec 5,2010 10:49am - My_Dying_Bride ""] mr. music in allston is in with someone who builds amps/ pedals... they could probably help if you call... i don't like some of the people that work there though |
| ______________________________________________ [Dec 5,2010 11:17am - markworkingrichards ""] I'll have to look into it; everything is expensive as shit there, so I'm guessing the repairs aren't going to be any less expensive. |
| ________________________________________________ [Dec 5,2010 3:01pm - the_taste_of_cigarettes ""] I can take a look at it for free, and if I don't have to buy parts, I'll fix it for free. If I can't fix it I'll just give it back. Just putting that on the table. |
| ____________________________________________ [Dec 5,2010 4:29pm - MarkFuckingRichards ""] Right on, I'll keep that in mind Nick. How much experience with this stuff do you have? |
| ________________________________________________ [Dec 5,2010 7:40pm - the_taste_of_cigarettes ""] I've built a few pedals, repaired a few, studied a bit with my father-in-law that's an electronics engineer, and read a ton on electronics. I've diagnosed and repaired two of my amps. Not starting a business or anything, I do this stuff for myself but if it's an adapter jack that's very easy to diagnose in minutes if not seconds with a multimeter and it's also easy to resolder it or put in a new jack. Mostly what I'll do is open the case, run the multimeter around the board, look for any obvious problems, and if I can't find any, close it up. If something is showing a weird reading I can usually figure out why and most often with discrete components the deal is to just replace that one part. Can't really save them unless it's dirt in a pot or something. I'd check traces to see if there's a break for some reason, check resistors to make sure they are reading correctly (they can blow, surprisingly), and see if all the areas that connect are, well, connecting. It's not much work, you get charged by most places for that but it's literally sticking probes in a few spots and looking at what the meter says. |

| ____________________________________________ [Dec 5,2010 9:54pm - MarkFuckingRichards ""] Nick, I may be in touch for you to check it out if Martins the curious electronics specialist doesn't have any luck. It seems to me the adapter jack is just pushed too far away from the outside of the casing; when I put a 9v adapter in, it doesn't go in nearly far enough and just wiggles around. Nothing looks wrong visually though. I guess we'll see what happens. |
| _________________________________________________ [Dec 5,2010 10:09pm - the_taste_of_cigarettes ""] Sure thing, no problem either way. Like I said, it's free and I'm not getting anything out of it but it's also barely any work at all to give it a once-over so I'm casual. |
| _________________________________ [Dec 5,2010 10:33pm - Martins ""] Well I'll just be doing the same sort of thing. I don't have an oscilloscope so if there are any problems beyond power-up I probably can't fix it but I have a lot of experience with troubleshooting electronics that are a bit more complex than a foot pedal though I've never dug around in a Moog before. |
| ____________________________________ [Dec 17,2010 10:09am - Bradsauce ""] I've got a shop and would be glad to take a look at it, if you like. I've worked on moog synths, never the pedals, but I'd imagine it's the same filter. I do charge though... |
| ______________________________________ [Dec 17,2010 10:21am - The_Rooster ""] If it's just the 9v adapter, I would pop it open and have a look yourself. Chances are, that socket is clipped in there somewhere... could be as simple as just reattaching the adapter socket, or tightening it up. Also could just be a wire that got detached from the socket inside. |
| ______________________________________________ [Dec 17,2010 10:32am - MarkFuckingRichards ""] I had opened it up, and couldn't see anything wrong; then again I am completely retarded when it comes to anything of the sort, and wouldn't want to fuck anything up further. Also, most likely there's nothing wrong with the pedal; just waiting on a different adapter to show up...this is most likely the issue. |
| ____________________________________ [Dec 17,2010 10:35am - Bradsauce ""] I think the power jack is just soldered to the same board as the jacks. I'd bet dollars to dicks that the solder joints are bunk. That's the problem with not having any strain relief on jacks. |
| ______________________________________________ [Dec 17,2010 10:56am - MarkFuckingRichards ""] We shall find out when the proper adapter comes in. |

I'd bet dollars to dicks that the solder joints are bunk. That's the problem with not having any strain relief on jacks. Yeah... that's one drawback that I've hypothesized about in regards to PCB mounted jacks/pots, etc. P-to-P wiring is more labor intensive, so it increases cost, which sucks, but I'd rather pay for that extra bit of labor in the final cost, knowing that it's built to last. |
| ______________________________________ [Dec 17,2010 12:11pm - The_Rooster ""] Also, are the nuts, etc. plastic on the Moogerfoogers? That would be worth a trip to the hardware store... gets some metal on there. |
| ______________________________________________ [Dec 17,2010 12:13pm - MarkFuckingRichards ""] I think they are plastic; Martins has had it for a bout a week, so I don't know for sure. |
| _________________________________ [Dec 17,2010 8:02pm - Martins ""] Nothing is wrong with PCBs (in general that is). The solder job is fine. I ordered the correct adapter. The Moogerfoogers use center positive adapters. I could hack a center negative one up or buy one from radioshack but they're always pieces of shit. There's also no real need to replace the nuts on the jacks. This is a high quality pedal for sure. |
