guitar built in fuzz factor, wiring

[guitarbobby]

This is what I think the wiring should be, but I'm not so certain, could use some expert advice!



My aim is to wire up a single humbucker pickup to 5 toggle switches:

1) The first switch is a series/parallel switch, in one position it connects the middle + and -  pickup leads to have 2 pickups in series, and in the other position, it connects + to +, and - to - for parallel wiring. There is one "hot" wire coming from this switch.

2) the coil cut switch just grounds one of the hot + pickup wires, to short out one of the pickups.

3) The battery switch just cuts out all leads to the battery so it isn't drained when I'm not using the effects.

4) The circuit on/off switch connects the hot signal to either a jumper (is this called true bypass?) or through the effects circuit. The circuit diagram is from [url http://membres.multimania.fr/davpseudo/ffactorx.htm, the second diagram. Except for the components the other 4 wires are "in", "out", "ground", and "+9v".

5) The kill switch shorts out the hot output wire to the ground.


This is probably child's play for you lot but I want to check what I have got wrong first, before I start drilling holes in stuff.

  2 wires are required for a closed circuit, 1 wire is an open circuit, you can use a stereo jack trick to lift the - of the battery from the circuit, this will eliminate all DC flow.
 Recommended to try the switch wiring as a separate project the first time around, there are threads and diagrams about this, the diagrams seem to lack the text, the thread texts are good and sometimes refer to a diagram. Using a DMM to test that the switch and lugs wiring assignment is correct and works properly.
 Also recommended is debugging the circuit outside the guitar, it is much easier to debug a fraction of a chain at a time, knowing everything else is right by 'thumbuzz' [put thumb on 'live' cable it 'buzzes'] or other source reaching amp to speaker.
 Having read quite a few posts about 'guitars with holes in them' [I have one here...] where fuzz unit once resided, but it screwed with the other effects too much and...and...got pulled, often it seems knowing exactly what is the desired effect before wiring the guitar ends up being a passive pickup/~typical controls.
Testing for 'it' outside the guitar is strongly recommended. 'It may prefer itself later in the chain, something else might not appreciate having it first in chain after PU's, thorough testing of the entire signal chain under the various effect conditions...how everything interacts..with all the 'normal' switching and control positions.
 There are pull/DPDTswitch/potentiometers, which allow true bypass and volume control with 1 knob, pretest the wiring/function before installing.

Thanks for the info

The switching seems pretty simple, and I understand how the signal interactions work, it's mostly the effects board and the battery wiring I don't understand. Also I only have one guitar so I can't really do separate projects

Yes I'm going to test the effect circuit first, but it has 5 pots on it, I want them mounted onto a pickguard so they aren't flapping around all over the place, and I don't have to make 15 wire connections for the 5 pots (=30 solders which I have to unsolder after testing )

If I made the pedal in a separate enclosure it would go first in the effects chain. I don't know exactly what it will sound like because I haven't made the effect, but I have heard clones on similar guitars before. TBH I love the idea of hundreds of buttons on a guitar.

It goes first in the chain, so it shouldn't make a difference if it's just inside the wooden body, just before the output jack, right?

There are pull/DPDTswitch/potentiometers, which allow true bypass and volume control with 1 knob, pretest the wiring/function before installing.

I don't like these, I prefer having more buttons on the guitar hell, I might just forget the circuits and mount some unwired knobs and buttons just to look cool! (or maybe not...)

This is what I was after. You say 2 wires, doesn't the ground count as a wire to make a closed loop?

Do you mean connect the -ve lead of the battery to the ring of the input jack? So that when a mono guitar cable goes into the jack, the ring and ground are connected, and when the cable is out of the jack, the battery is disconnected?

I can do this, but I thought (maybe incorrectly?) that I would just have a separate switch to cut off the battery, because I leave a cable plugged into the guitar jack a lot of the time, and also I wouldn't be using the inbuilt effect (and battery) every time I use the guitar. So instead of using the input jack to complete the circuit for the battery, I just have a separate DPDT switch so I can control when the battery is on or off.

Furthermore I don't understand how the battery works or what it does in the effect circuit - is the -ve end supposed to share the same ground as everything else that is grounded?
