Sorry guys for this one; however, this is with regard to Bourns Dual Gang Push Pull (I know uggh). Anyway, I read on the forum that John has a diagram for a two tone using the said pot before the 2 volumes. I can not find it anywhere on the forum. Could one of you veterans point me in the right direction? Thank you...
John, et. al., the article pertains to the usage of Dual Gang pots is quite helpful, as are the schematics of the wiring they’re integrated into; nonetheless, I’m still struggling with a wiring diagram that utilizes the Bourns Dual Gang Push-Pull PDB183-GTR22 pot. I know you’re probably all sick of me bringing this subject up, but is there a diagram that actually illustrates how the pot can be utilized effectively in tone scenarios - in lieu of descriptions of its potential use? Does an actual wiring schematic exist that shows how this pot can be used as a two tone pot within the context of avoiding problematic wiring entanglements? I promise to never bring up this pot again if I could see a visual of it in action in a diagram. Not trying to be snarfy, I just don’t get it. I’m embarrassed to say that I can’t envision this application with this pot.
Im not clear on what you are really aiming to do. How do you want your design to work? what pickups and what knob and switch functions?
Dual-ganed pots are rare in guitars. That two volume Strat thread that I linked is the only type of application I can think of. Its for a guitar where there are two volumes but only one tone knob, but without the quirks of putting tone after volume, so the tone is in two channels (one before each volume) on a single knob.
Now the Bourne dual-gang push pull is an even rarer thing. We didnt know about it for a long time , or maybe it didn't exist!
So, maybe there is no diagram? But, you should realise that, as with normal push pulls the switch part is a completely seperate independent thing, on the same shaft as the pots. So, take another look in the two volume Strat thread. The push pull switches on the various versions could have been on any pot. Just imagine that one of them gets split off the back of its pot, and stuck onto the dusl-gang tone, dragging all the wires with it unchanged. In that way, you could imagine how the dual-gang pp pot might be used?
Thanks John, I’ve built your two volume Strat with good results. I’ve yet to discern what my aim is with this pot. On occasion, I think of the parameters of what I can do with a pot in a future harness. Much like a mad scientist. I am looking at it and it befuddles me given it seems one can accomplish a push pull tone pot with a regular push pull. With the two gangs, utilization of the switch eludes me as applied to a tone cap situation. Don’t worry about it. As you said, they are rare in guitars. If I continue to mess with it, I might discover some purpose. The only diagram that I am aware of is a lo cut hi cut wiring, that can be done with a regular push pull. This one I’m letting go of.
Just thinking of ideas for this pot, and given a 2V 1T arrangement, to make sense of having a dual-gang, and, keeping it all within the realm of tone controls (rather than other switched functions), how about:
Pull the knob to engage a fixed bass cut on both channels, or,
Pull the knob to cut out both tone controls, like a no-load pot (assuming a dual-ganged no-load is not existant, or,
Pull knob to change both caps to much smaller values, maybe to cut the pots too to directly put a cap across each pickup for a honky woman-tone.
