I'm building a sustainer system (cos I'm poor, wooo) and just got to thinking, for the sake of stealth on the body, could an SD Triple Shot ring be used for the on/off and normal/harmonic mode switches instead of having to drill the body? I've looked all over the place but no one seems to have thought of this. I'm rather hoping it's down to lack of interest as opposed to it being impossible. ^^;

It depends...for the harmonic switch, you need a dpdt which it can probably handle. If yo only have a bridge pickup in the guitar, sure any switch that will turn the power on will be sufficient.
If you have any other pickup (neck, middle, etc) you will need a 4pdt switch to turn the the power on, bypass the selector or other pups, and re-select the bridge in HB mode.
This, I doubt it would do.
The GN2 guys also worked out a way to use a super switch to do the sustainer functions as I recall if you have a strat type selector option...that you have pup rings, sounds like that might not be an option.
The idea of such things and similar was proposed and even tried in various way back in 2004 before they existed as well as other 'stealth' options. Two push pull pots will work on a simple one pickup guitar for instance. I made a prototype trem arm that had a car wiper like control that pushed to turn on and twisted for harmonic options...but, you don't want to attempt such fantasies in DIY I can assure you.
Many people struggle with the sustainer project, it is an advanced thing that needs competency in various aspects to work (circuit building, coil winding, advanced wiring skills, etc). As a result, before considering controls, always build the circuit, test it works well with a speaker. Take a Y signal from the guitar and test that it works by holding it above the strings well away from other pickups before even contemplating such aspects or if it will work for you at all.
The 'drive' control is an optional thing, you need to tune the gain for various guitars and driver qualities but this could be done with a trim pot and so that control left out of the project.
hope that helps...generally sustainer threads are not given a lot of airplay on forums and to avoid trouble, I handle most things out of the public view...as I see fit.
edit....I've not seen a triple shot, but I would not imagine that these thins would be very convenient nor sturdy. One thing that was cool and can be done on a simple one pup guitar and featured in a way on early roland synths, are a tiny little momentary switch to intermittently activate the sustainer by touching the 'ring'...many if not most of the 2003 hex sustainer things had that kind of thing as a feature.

Thanks for the advice and quick reply. I'd completely forgotten about selecting the bridge lol, guess I'll just have to go with the two switches. The sustainer's mostly a side project that I'm trying to work out while I'm working on other guitars, to be honest.

That's cool...always answer such questions wtih some trepidation...had a troll attack this morning... But I will offer these videos tha might be encouraging and at least what needs to be achieved before 'installing'... This sustainer is being built for a tele, so uses a blocked up tele neck pup. Driver ~ PVA glue potted 0.2mm wire, well wound coil. Circuit ~ modified "Ruby". Bridge pickup should be noise canceling or HB. I generally offer assistance by email. As here, test the circuit is working properly with a speaker, replace with a driver, test well away from all pickups up the neck. If it performs as expected as this does, then it will work even better when installed correctly. My tele uses a similar thing and can be found in the gallery along with sound clips...you will see there that the internal wiring can get quite complicated.

c-27: Here's what we can tell you about the switch logic. As you can see, these are 2 DPDT switches, but the two are internally connected on the circuit board. While one could cut the traces to separate the two switches, the problem then becomes how you can cram additional wires under the pickup ring. SD TripleShot™ Switch LogicAFAIK, no one has tried any of the suggestions made in that thread. When the Tripleshots were first introduced, ChrisK and I placed an advance order for a pair. We were going to each take one of the two for experimentation. But SD then cancelled all the advance orders and recalled the ones they had shipped because of QC problems. It was about 6 months' later that they re-introduced them, but ChrisK and I were frustrated by that point and never reordered them.

Yes...welcome to GN2..sorry distracted by the S word
Another thought come to mind thing besides I would presume the kinds of switches used may not be that strong or convenient.
Generally, and necessary on a multi-pickup guitar, the phase switch swaps over the phase of the driver wires. The driver wires are an extension of the driving coil and carries a fair bit of interferance causing EMI. One needs to try and keep the signal from the driver well clear of the bridge pup especially so you'd not want to put those near a working pup like the bridge pup ring anyway.
As newey also says, there is not much room anyway and the sustainer has a lot of wires involved, so it would be a tricky thing.
Potentially, with care and good and very thin wires, you might be able to build a driver for a HB neck pup slot (lose the neck pup) and use such switches with the circuit under it perhaps...be tricky but I don't think these kinds of switches would be particularly sturdy or convenient in practice.

Anyway...there are lots of cool things for wiring guitars here and other projects at least as cool as a sustainer so I hope you look around.
