My brain wouldn't cooperate with me today. You ever get that surreal "glitch in the matrix" feeling? I had spent about an hour trying to get the active tone circuit working in my guitar. Each time I connected it, nothing, nada, no dice, go fish. There's a switch that disengages the circuit, so I flip that and the guitar makes sound in passive mode. So that means everything is wired properly.
The active circuit is almost an exact duplicate of the one in my other guitar. So I think "ok let's test it in that guitar, shame to remove it after it's been there for 30 odd years, but at least I will rule out this circuit."
So carefully I swapped it in, one wire at a time. And...it worked perfectly. So far so good. I wire up the factory made circuit to my DIY guitar. Nothing again!
Now I'm getting a bit irritated. I check every connection, tone it out with a multi meter. Everything checks out. Okay, try again. Nothing. Double check all connections against the schematic and cross reference to the factory made guitar. All good.
So now I'm thinking, perhaps the pickups are wired weird and effectively grounding out the active tone circuit. I give in, start desoldering the pickups, and just twist the wires together just as they had been soldered. And...It works! Awesome, okay, solder everything back together, plug in the lead, attached the 9v battery. And...nothing.
Repeat the same thing again, desolder, twist wires together. It works. Solder the twisted wires. It stops working.
Completely baffling! I sat there looking at the wiring completely at a loss hoping my brain would come up with some theory on what was going wrong, but it just went blank, I felt like I was going mad. I give up, decide that there must be some issue with the wires I've used. I replace everything. And...nothing...not a peep. I desolder, twist wires together, it works, solder wires, it stops working.
Each time I did this I had been careful to unplug the guitar cable and battery just in case an earth loop via the soldering iron fried the chip on the active circuit. So this time, although a little risky, I twisted the wires together, it worked, kept the connection to the amplifier, soldered whilst it was making some awful buzzing noises. And...it works! Totally fine!
I'm sure there is some rational reason for this, but I can't think of one. It just didn't make any sense, how can soldering wires together cause a loss of connection? But everything simultaneously is confirmed connected with a multi meter. This is the most utterly strange thing to happen to me in a long time. It was like the laws of physics had gone screwy.
Perseverance pays off despite the uncooperative brain!And...it works! Totally fine!
True! I'm probably never going to be able to explain it, but at one point I honestly felt like there was some sort of bug with reality. As soon as I made the circuit physically part of the guitar it just wouldn't work lol!Perseverance pays off despite the uncooperative brain!
That’s awesome how the slide looks like a spike into the brain.
@Outdated, when can we expect the written anthology of all of your wild and wacky stories you have collected through life? I’m sure it would be a best sellerWhen I was a kid an old bloke up the end of my street was putting some shelving up in his shed, and he dropped the drill. He managed to catch it again just as the drill bit went into his skull. He very carefully undid the drill chuck and put the drill away then drove himself to hospital.
He said when he got there he couldn't understand why they were all making such a fuss about it and in the end he got impatient with them and told them that if they faff around for much longer he'd have a go at pulling it out himself.
