Note: This is only a concept for now, since I don't have the finances ATM to do the full mod, but some smaller things might be doable very soon.

The guitar I want to mod is a B.C.Rich Assasin QX6, which you can see in my gallery if you wish.
The guitar already has additional non-standard controls, like individual coil-taps and a reverse phase switch for the middle position (both pups). Very useful.

Now, these are all 2-way switches, and I was planning to replace the coil-tap switches with 3-way DPDT on-on-on switches so I could have the additional combination of individual parallel-wired humbuckers, so I'd get series/split/parallel switching. I already got these figured out...it's easily doable.

The next thing I'm looking for is making the Megabucker mod - installing a switch to enable two Hums wired in series, in phase, while the pickup selector is in the middle, making one "huge" humbucker, which I think is very useful for extra power.

Now, my main question is: Is it possible to have just one switch for out-of-phase/normal/megabucker switching, or would i have to install another switch just to get the megabucker option? And is a combination of both out-of-phase and megabucker even possible? What kind of switch would I need for that?

( I also have plans of installing a GraphTech Piezzo bridge and preamp, with it's volume control and a 3-way switch for selecting magnetic/both/piezzo pickups. I would put the piezzo volume instead of the mag tone pot, and replace the mag volume pot with a push-pull pot to create a Vol-pot/tone-switch combo (a regular Vol pot, and when enabled, simulating a tone pot turned all the way down, since it's of no real use as a pot anyway).)

The mag pickups are staying the same, Rockfield Mafias, I just think they're fantastic.

This was a lot of writing for sure. What do ya think? Have any ideas 'bout the megabucker mod? If you know any helpful sites regarding these issues of mine, please direct me there biggrin.gif

P.S. If I this mod is possible, and when the peizzo is installed, it would give me a total of 67 combinations of pickups biggrin.gif

I think I got it...this would be the schematic. (without the piezzo pickup, that'll come in later)

There are some disadvantages to this design, and I might drop out SW4 because of them: when flicked, this switch puts Neck and Bridge pickups in series and gives a very powerful output. It should work only in middle position, but it does the same thing when activated in neck position, and cuts all signals when in bridge mode. Sounds like trouble, I know...that's why I might drop it out, leave just the reverse phase.

The Tone-switch should work like a Tone-pot at positions 10 or 0, if I did it right.

Taking out the tone pot will make the overall sound a bit brighter, but I've prepared countermeasures in case I don't like it that way. It has to go out however, since the piezzo Vol is going in it's place.

@ Ivan - Actually, I've mistaken, there are much more than 67 combinations with the piezzo, in fact, there should be over 130 combs laugh.gif , however, a lot of them won't be very useful (mostly the mid position combos, they're just subtly different), and the ones with the tone-switch on will most likely all sound the same. I'm aiming for at least 20-25 useful combos (the other 110 are inevitable).

I'll be contacting Todd Rockfield @ Rockfield Pickups to ask him what he thinks of these pups being wired in such ways.

Jimmy Page had a very similar mod...
