aboubou Posted October 7, 2020 Report Share Posted October 7, 2020 Hello every one !I'm building a tele guitar, and I would like to have some nice electronic feature. Like a low cut on a mini toggle switch (+-160Hz), and the possibility to switch 50s/modern wiring via a mini toggle switch too. I'll use a Schaller megaswitch M.But I really don't know how to configure it right, and which cap to choose. Any advise is welcome.Here is the incomplete wiring diagram... if some one could help me to fill it, it would be very appreciated ! :-)Amaury Quote Link to comment Share on other sites More sharing options...
aboubou Posted October 7, 2020 Author Report Share Posted October 7, 2020 Here is the diagram from Schaller. Quote Link to comment Share on other sites More sharing options...

Do you mean these two variants? Â 11 hours ago, aboubou said: Here is the diagram from Schaller. There's something very wrong with the way that diagram has been presented. There aren't enough solder tabs drawn on the Megaswitch, and nearly all of them are shown bridged together which would be completely incorrect. The Schaller product page for the Megaswitch has more detail regarding what the wiring scheme actually should be. Quote Link to comment Share on other sites More sharing options...
aboubou Posted October 7, 2020 Author Report Share Posted October 7, 2020 Hi, No I don't mean "dark tone" like early tele, but 50s wiring, like Gibson did, I think. The full shema that I post is taken from the website that you post (official schaller site...) So I think it's ok. Visualy it's not clear cause there are two soldering sides, that are mixed on the drawing. Search a picture on the net and you will understand. Quote Link to comment Share on other sites More sharing options...
curtisa Posted October 7, 2020 Report Share Posted October 7, 2020 The only difference between the Gibson 50s/modern wiring variants is how the tone circuit is connected to the volume pot. In the 50s style the tone circuit is attached to the toggle switch/wiper (outgoing) side of the volume pot. On the modern wiring the tone circuit is attached to the pickup/hot (incoming) side of the volume pot. Adapting for the Telecaster where the relative positions of the toggle switch and pickups are different to a Les Paul, something like this should do it:  2 hours ago, aboubou said: The full shema that I post is taken from the website that you post (official schaller site...)

I was more highlighting that the diagram by itself does not give the full details about the wiring scheme and that it shouldn't be used to as-is when constructing the circuit.

aboubou Posted October 8, 2020 Author Report Share Posted October 8, 2020 Thanks Curtisa ! It progress next step, would like to add a toggle switch for the low cut, or a push-pull pot if it's simplier. Do you have a clue ? Quote Link to comment Share on other sites More sharing options...
curtisa Posted October 8, 2020 Report Share Posted October 8, 2020 OK, how about this: Â The capacitor value will be very dependent on the surrounding circuitry. Caps are cheap. If I were you I'd just buy a handful of different values ranging from 0.001uF to 0.047uF and try them in the guitar until you find one that sounds right to your ears.

aboubou Posted October 8, 2020 Author Report Share Posted October 8, 2020 Hi Curtisa, Thank you really much for the time you spend doing it. I really apreciate ! Will try it (in à few weeks, still have to build thé guitar body !) and let you know.  Thanks again. If you have any advice or suggestion, don't hesitate ! Quote Link to comment Share on other sites More sharing options...
aboubou Posted October 8, 2020 Author Report Share Posted October 8, 2020 Another question : have I to connect the métal housing of the neck PU to ground ? Quote Link to comment Share on other sites More sharing options...
curtisa Posted October 8, 2020 Report Share Posted October 8, 2020 No, you don't have to. Quote Link to comment Share on other sites More sharing options...
aboubou Posted October 20, 2020 Author Report Share Posted October 20, 2020 Hi, Another caprice, do you think it is possible to add a bypass straight to the output for the neck PU, with a push/pull on the vol pot? The idea is to make a bridge PU blend in Quote Link to comment Share on other sites More sharing options...
curtisa Posted October 22, 2020 Report Share Posted October 22, 2020 How's this? The push-pull switch block is drawn off to one side for clarity, but would be physically installed on the rear of the volume pot. Quote Link to comment Share on other sites More sharing options...
aboubou Posted October 22, 2020 Author Report Share Posted October 22, 2020 That's really cool man ! I really Appreciate, and can't wait to try it ! Quote Link to comment Share on other sites More sharing options...
aboubou Posted May 26, 2021 Author Report Share Posted May 26, 2021 Hello !I finally found the time to achieve my project. I used this diagram, with 3 caps 0,022Ă¹Â :And unfortunately it doesn't work like it should. The 2 mini toggle switches are totally ineffective, and the positions of the 5way switch are not ok.I should have:1 bridge2 bridge and neck out of phase parallel3 bridge and neck in phase parallel4 bridge and neck in phase in series5 neckAnd I have:1 bridge2 neck with no treble3 bridge and neck: parallel or serie I don't know4 bridge5 neckHas someone an idea to solve the situation ?
