Greetings,
First post here...
In the process of doing the electronics on a partscaster build.
Looking to do the following....
5 way 2 Pole Super Switch - It's an Oaks Grisby unit if it matters
1 - Bridge
2 - Bridge / Middle
3 - Bridge and Neck
4 - Middle and Neck
5 - Neck
2 Vol post - Each volume pot is a DPDT push / pull. I want separate volume controls between the bridge and neck. The DPDT pots are CTS if it matters
Vol Pot 1 - Bridge only, selectable between series/parrallel (stupid newbie question alert....series is the normal humbucker sound?, and parallel would mimic single coil?)
Vol Pot 2 - Neck and Middle, neck selectable between series/ parallel (if the mid pup could also be selectable on the pot, great, but more of "wouldn't that be nice" than necessary
1 Tone - DPDT push / pull - Universal for all pups. I'm not sure what I want to do here with the push / pull, but initially thinking selectable between .47 and .22 (other recommended ideas?)
Sorry for the newbie questions...
- Can the "common" be routed to the tone control from the 5 way?
- I've seen some diagrams using the 5 way 2 pole super switch, and for example it was shown that the bridge pup connects to the 1,2,3 terminals. Does one solder in separate wires from each connection, or does one thread the wire through all the connections and then solder the wire in? I, for lack of a better word, suck at soldering and am thinking threading the wire through the multiple connection points would make a lot less mess?
- Regarding position 3 on the 5 way, where it's bridge and neck, presumably if the 2 volume pots were pulled up to parallel, then the combined tone would be 2 single coils in the neighborhood of a Tele?
Very much appreciate the help....thanks, Ken

rauchman- Hello and Welcome to G-Nutz2!A couple of points here: First, as far as soldering the bridge pickup to lugs 1, 2 and 3, do not "thread wires". Use solder. The wire from the pickup will be soldered to one of the lugs, then the other lugs will be "jumpered" together with short pieces of wire. You started out talking about a "partcaster", so I was thinking single coil pickups, but now we're talking HBs- Is this to be a HSH- type, with HBs at the neck and bridge positions? And the 2 P/P pot switches will then be switching their respective HB coils from series to parallel? If that is what you mean, it is doable, but forget trying to select the middle pup as well, you'd need more switching. You'll need all the lugs on the DPDT P/P pots to do the sereis/parallel switching, no room for anything more. A 2-pole "Superswitch" is what we call a "half-Superswitch", as a regular Superswitch will have 4 poles (24 lugs total). Do you in fact have the "Half Superswitch, i.e., does it have 12 lugs total, 6 per side? If you want to have a Master Tone control as you describe, this is required reading: JohnH's Strat with 2 VolumesThe essential take-away there is to use a dual-gang pot (NOT a concentric pot) for the master tone control so as to isolate the individual volume controls from each other. If you use a regular pot with the two volumes, your volume pots will interact with each other. There are dual-gang pots with DPDT push/pull switches but these are fairly rare. SInce you don't really have a solid idea for the 3rd P/P pot, you could just forget that and just use a regular dual-gang pot. No, see the above. With a 2-pole Superswitch, you'll need both the commons to control pickup selection. Series is the normal HB sound. a Parallel-wired HB has somewhat less output, and perhaps veers more towards a SC sound, but I don't really think it mimics a single coil. To my ears, it is its own sound. Unlike splitting a HB to a single coil, it will also be hum-cancelling. |

Thanks for the welcome and great info.

OK, first off, no, you can't just wire the pickups from a lug to the volume pot, since the common lug is what makes this a "switch". If you were to wire, say, the bridge pickup to lugs 1,2 and 3 (as you will be doing), and from there to the volume pot, that pickup will always be on, no switching would occur. As to adapting it to your "half superswitch", your switch should look like this:  Just to have a way to talk about it, we'll arbitrarily designate the left-hand side as "pole A", with its common lug and 5 position lugs. The right hand side will be "pole B". Note that, as shown in the picture, the lever is pointed towards the bridge, and the lugs are numbered accordingly- Bridge is position "1", Neck is "5". As for the wiring, I can do a diagram but it may be a day or so. However, I am having difficulty envisioning how to do what you want and have the one volume control for both the neck and middle pickups. You may need a regular 4-pole superswitch to do that. If you have the 2 volumes for only the neck and bridge, it's easily done, but I'm not "seeing" it with the half-superswitch controlling one volume for both middle and neck. JohnH's version uses a regular 5-way switch, and takes advantage of the "shorting connections" at positions 2 and 4 for the neck/mid volume. But because you want to have N + B at position 3, this throws a wrench into the wiring of the separate volume pots. But there are many brighter minds than mine around here, maybe someone else has an idea. It will be partially hum-cancelling, as the split coil will be RWRP with respect to only one of the 2 middle coils. Since you are using 3 HBs, all positions will be hum-cancelling unless you elect to split one or more of the HBs to a single coil. Well, a regular pot. This is essentially 2 pot elements controlled by a single shaft. |

Hello...You would require 1 switch for every pickup to switch between arrangement + equal. To the extent changing the pickups, it truly relies upon what you don't care for about the stock pickups. What do you need from a center pickup? On the off chance that you need adaptability, I would recommend a Classic Stack in the center for a silent genuine single loop sound. What would you like to change about the neck and scaffold pickups? The Distortions are incredible pickups, however not the most flexible. I'd pick lower yield pickups and lift them later on, if adaptability is a serious deal to you. pcb assembly quote |
