Rangemaster switch

Hi, I'm new here. I've been making fuzz boxes for about a year with varied success. My first project was a Rangemaster, however which I made from R.G. Keen's plans at geofex. Now these plans are fine but they do not explain how the wiring connects to the switch. I got mine working, but it was by trial and error. Still the pedal is a killer. What I am trying to do now is make one with a DPDT switch, and I'm damned if I can figure out how to wire the switch. I have once again followed the geofex directions and with the switch connected in standard bypass mode and I can get it working, but the volume is cut way back. I've tried wiring the switch according to photos of an old rangemaster but with that I get nothing. Can anybody give me an idea how the swich is supposed to be wired? Thanks. This is the terminal strip version.

Right ... moving along at the speed of molasses; I've got the switch wired as shown in most (at least all I've seen) photos of an actual Rangemaster. Bypass works fine but when I switch it in I get about a quarter volume. If I short the 9v input to ground the sound goes dead (of course) and comes back at full volume, great tone, for about five seconds after which it fades back to previous levels. I'm investigating this phenomenon but any help would be appreciated.

Dr. T. Thanks for that. tried it ... no go. Redid the wiring - nothing. Checked the jacks - nope. The frustrating thing is that I've done this the same way as one I have that works; the only difference is that this is a DPDT switch, and the other is a 3PDT. I will now tear the damned thing apart and rebuild it.

All - right, moving along. Could someone possibly post a wiring diagram of a Rangemaster including the wiring to switch (DPDT not 3PDT please). I have tried everything I can think of and nothing works. I know it can be done. Other people do it. Heck, I've done it, but I did it with a 3PDT switch and led and even that series of connexions doesn't make sense when I look at it. What I am getting with mine is some exaggerated treble when I switch it on, but it works with the battery disconnected and the transistor removed, so I suspect it is just some sort of degraded normal signal. if I can see a wiring setup that works i can decide if I need to order new parts. Thanks

I forgot where this came from, so I can't give credit due;

LIFT OFF! Thanks Theox; I got it a different way though. For some reason that layout doesn't work for this. I used the setup from the GGG website (which I had overlooked) and it worked like a charm.
