Guitar: Humbucker selector switch problem

Tue, 24 Feb 2026 08:35:35 -0700

I am stumped! I just acquired a 25 year old Guild X-150D. It is great but I now have a problem. It has 2 humbuckers, 2 volume and 2 tone pots. When I select either pickup it works fine. When I select BOTH pickups (switch in centre position) only the bridge pickup plays. I have pulled out the switch, examined it and tested it with an ohmmeter. It tests fine on the meter. Both pickups connected. Any ideas?????

Korg Monologue: 3 notes are not working suddenly

Mon, 15 Dec 2025 22:45:40 -0700

Three notes on my Korg monologue are suddenly not working. I've seen other similar repair threads on Korg keyboards where 3 or more keys stop working that are the same distance apart. I don't know the correct terms but I imagine there is a component that these notes - G,B ,D# are all attached to. my electronic skills are limited. I tried cleaning some connections gently with isopropyl so far to no success.

I include images with bad notes circled on red and another photo further up the scale where there appears to be corrosion (green arrow) but would it have an affect on those notes? I could test with a multimeter if I knew what connection I was testing for.

Teenage Engineering OP-Z: The front buttoms pcb (op-z)? Where do I find?

Thu, 27 Nov 2025 06:51:04 -0700

Hello guys, i wish you are all really well!

I have a question, after coming all the way to Brasil with my op-z looking for someone to fix it, which i found just in Berlin for now.

My Op-z is 40% fixed by now (it was problems of dirty inside, humidity, etc) and now, Tom, which fix for SchenidersLaden with his team, told me that i should find some Front Buttoms Pcb for it, to continue the fixing - ‚cause some of them are not working properly, and this bothers me while composing.

Do you guys have some of them - used or new - to sell or give it to me or know where i could find it?

This would help a lot not just my artistic carreer, but my lufe as a whole.

I keep searching from here,

Wishing again all the best for your

Kindly

Pedro Máia

Obs.: By the way, the op-z module and the cables that i got from you are working pretty well! Just the cable of charging the op-z that lost all it‘s skin, so it‘s like crude now, with the silver cables inside appearing - could it be harmful for me?

DJ Controller: Hercules T7 DJ Controller Pitch connected to Serato not working

I have a Hercules T7 DJ Controller. My pitch control on the left side connected to Serato DJ Program, as soon as I move it up it down, it barely moves. So, I figure maybe the pitch control needs to be replaced.

Teenage Engineering OP-1: The “4” track button is not working

Tue, 30 Sep 2025 12:20:13 -0700

Hey, so the four button on my used OP1 stopped working recently. I noticed it a few weeks ago. But, when I wiggled the button it seemed to work again. But, now it doesn’t work at all. I assume it’s a mechanical issue. Can someone tell me what I can do to fix this button myself?

Thanks,

Jared

Korg B1: Problem with circuit board

Mon, 01 Sep 2025 07:45:35 -0700

Hello everyone,

My C2 is not working anymore. I opened it up and I think the soldering joint is corroded. I am not an expert. I have never worked with circuit boards so I am not sure if that's the case. I attach pictures of it. If it is the soldering joints. How hard would it be to fix it myself?
