Here's where I'm at so far. What do you guys think?  BTW, I wanted to put this here because it's still a work in progress, and I didn't want to make a mess of the other thread until I knew for sure that this was a keeper. What do you guys think? Incidentally, I notice that I could use some labeling on there, so that's on the way. For right now, if you're familiar with the other layout, then everything should be understandable. Chesh |

FINALLY! Chesh nice work. If I could understand what new switch does what. I'll give you some time for that one though.

I can't pretend to understant what the wiring is doing...
The presence of a superswitch and two push-pull pots is about as much understanding as I can muster at the moment. What components are the mode switcher and phase inverter?

What components are the mode switcher and phase inverter? The splitters are DPDT on-on switches (either mini-toggles or a push/pulls). The mode switcher and phase inverter are 4PDT on-on switches (either mini-toggles or in some instances an S-1 Switch). It all looks very complex, but you can actually get some 4PDT mini-toggles for a few bucks a pop. Pretty cost-effective. |

Righto - they looked more complicated than I thought ;D

Righto - they looked more complicated than I thought ;D Yes, it does . . . but it's not.  The Phase Inverter is just a regular DPDT phase inverter x2. On the right we have the standard phase inverter for the N pickup, and on the left we have the same standard phase inverter for the M pickup for the 4th position only on the SuperSwitch. That way, no matter what position the SuperSwitch is in, you will always have phase inversion. In positions 1-3,& 5, N does the honors. In position 4, with no N selected, M does the honors. The Splitters are not proper splitters, but in fact coil bypassers. That way the pickups can be phase inverted and the coils ran in series. Chesh |

I just put some inverters in my guitar (like the ones you show) Boy is it a pain to wire those little things up. They are worth it though.

I've actually found that the inverters give my guitar a sharper tone. It makes it a better lead guitar (in my opinion). I've also found that, when the pickups are opposite, there is less hum.

Hey Chesh
Ive come to the view that you have a very clever design here. Your basic drawing has been up for a while, but I only recently worked through it.
Forgive me for saying this, but somehow the drawing takes more work to follow that it might. I think it is due to the un-seen connections, eg neck to output, bridge to ground, and the use of letters that need to be mentally connected up. Its all there in the post, but it does not quite leap off the page. BTW, I like hand sketches too.
The reason I studied your design was that, while on vacation, I was looking to develop a design with a superswitch, and minimal other switches that gives almost stock appearance, and stock operational modes, plus the best selection of further modes with the mode switch. I think you have achieved this, with the 'switch-up' options in my view, being the best selection of a further five modes. So I gave up trying to reinvent it and got on with my vacation!
One question for you, relating to a slight concern. The neck pup is always connected to the hot output, so that when neck is not active, it hangs from the hot, potentially picking up noise like a loose peice of wire. Its pretty much inherent in this design, but on other designs some of us try to avoid this. Question is, does this make a difference? When you select a mode with say just the bridge and middle only (with neck hanging), do you get any more hum than with neck and middle only? Both of these should be basically hum cancelling, but one has the hanging from hot issue while the other does not. If you could have a listen to this on your build, it would be a valuable fact. The worst-case way to test it would be to cosy-up to a CRT monitor or TV to maximise possible hum.
Any way, it is a cool design!
cheers
John

Second, this is in the betastages, so I can't answer that question about the N hanging from hot, tho thank you for finally encapsulating what that actually means. While I don't know if that would be an issue, what I can tell you is that that is pretty easy to solve for, as it is, specifically using an 8P5T UltraMegaSwitch. More later. Chesh |
