Delivered today.Bridge pickup nothing but mostly feedback.Turn both pickups on and toggle to the middle position and no sound.Toggle to neck pickup and that seems to work fine.The toggle switch seems to have a lot of side to side play in it compared to my other SC-500 which has none.Your thoughts please.

Check the switch hasn't had a knock during transport, they use the box type switches. They can come apart or partially apart. Or possibly you have a bad solder joint? The switches are quite vulnerable with weighty LP type guitars in transport, I would hope they could come up with something more substantial on the swith rather than just a square of polystyrene as protection.
Checked wiring and everything looks intact.I will let Thomann figure this out.The other guitar that came with the shipment the TE-90FLT Tele is bone stock amazing.I have bought 5 Harley Benton's this year and all were stellar except this last SC-500.I have no doubt's Thomann will fix it.

It seems something is shorting the bridge pick-up, as when you turn its volume down. If the circuit were open (bad connection) it would make no sound but wouldn't kill the neck pick-up in middle position.

The side to side movement/play is strange? Is the switch JA branded? Having had one of those apart there should be no wobble and it should be a firm/tight action on the switch. Two nice guitars, the black SC looks killer 👍
I checked all the wiring and everything looks normal.I will wait for Thomann's response then take it over to my luthier friend to diagnose and maybe replace the toggle switch or whatever he suggests.Other then that the guitar is awesome.
My first SC-500,the white one is insane for the $141 I paid for it.Perfect out of the box and the pickups blew me away also.Diehard Gibson fans once they discover Thomann/Harley Benton.......Gibson and their over priced,chinese type lazy quality control garbage will be over!They can go play authentic until Hell freezes over for all I care.
I do like the look of the white 500, I'm fighting the gas not to order one. 😕
The black one is good too but that white does look classy.
It cost me $141......that is lunch money bro!Order it NOW!My black one has minor wiring issues that Thomann will fix.These guitars are amazing axes.They should......in a correct world put Gibson out of business.
Yes, turning down one pick-up in middle position turns the other down too. It is intentional on Les Pauls and related. It confused me the first time I experienced it. I thought it was faulty but that's the way the wiring is designed. I suppose the idea was to turn the instrument silent with just one knob.
I do not see how the guy at Thomann thought the white guitar was any different. Both behave the same way, only the black one has a dodgy switch and a feedback issue.
The feedback is not an electronic problem. There is no way a passive circuit could generate this and it is always the same frequency no matter what you play. There must be a mechanical issue with the pick-up. I would try touching it while playing, see if something stops vibrating and find out how to prevent it. I had a vibrating pick-up which I had taken too low on an Ibanez. The spring around the screw was no longer pushing on it and it caused some silly vibration while playing.
I wonder if the switch can be tightened. It would save the bother of soldering in a replacement but this is not what causes any other issues.
I'm also confused as to why Thomann are saying the wiring's different when both guitars behave the same way. I was indeed going to mention that this would be normal behaviour for a Les Paul with one volume turned right down but assumed that this wasn't when it was happening because you already had experience with one. Interesting that you'd never noticed it before on the white one. It's designed to be that way and is a useful way of getting kill switch stuttering effects.
Certainly sounds like microphonic pickups to me. One way I test this is to shout into them with a delay or reverb pedal on. You'll hear your voice through the amp. These can be a nightmare with high gain sounds but quite lovely otherwise. Some folks refuse to pot their pickups because they want it. Will they squeal if you are not touching the strings and just let the gain generate it? I'm sure I read somewhere that Gibson didn't originally pot their pickups. I'll see if I can find that.
Would you say the behaviour is similar to these ones?

The only way the switch could possibly be "tightened" would require desoldering it from the guitar as the pup wire attach to the lugs on the body of the switch and the ground wires attach to the casing. So to take it apart (to get at the contact plate) it has to be disconnected.
If it is a JA branded switch the only thing that would make it loose is if the plastic spike with a ball on the end (the ball sits in the dish in the contact plate) that slots into the bottom of the lever is damaged. Having had one apart there is no way to "tighten" the switch. In my opinion for the switch to have lateral movent the plastic ball must be worn or damaged. If you have one apart you'll know what I mean.
I agree with the other guys on the controls on LP's and how they are wired I believe there is a name/term for how the volume works. As for the feedback from the pickup your luthier friend should be able to find the cause and if its microphonic or other? Hope you get it sorted soon, best of luck.
