'Ultimate' mad professor wiring?

Re: 'Ultimate' mad professor wiring?

TeaAt5- Its great to hear that you are moving forward and have explored so many options- It's great to experiment to find what works for you and I especially like your bass rolloff thinking

Thanks ZS, I have learned so much already through the process! I want to add a master bass roll-off but now I'm not sure I really want to drill any holes!

Keep in mind that you can do bass contour as a switch so you can keep all knobs as they are- the Yamaha revstars do it that way- it has the advantage of flipping directly between significantly tones and you can tune it in with a trim pot that lives in the cavity-

But I do love the knob approach because it's so nice to drive the gain up a bit and back it off and I never do it exactly the same way twice

Re: 'Ultimate' mad professor wiring?

I'm coming in late on this thread, but it is a very interesting read and I hope our OP is ecstatic with the finished build.

I have spent several decades trying out every scheme I could find, and ditching many of them soon after assembly. But I did learn a few things along the way! Number 1 is that whatever you come up with it needs to be fairly intuitive and easy to use in the heat of the battle. My Strat-like guitars have evolved into having either a blender pot, or an extra switch to engage a pickup. My Les Pauls & SGs are mainly stock with a few additions like resistors and/or capacitors. My main Les Paul has survived with the Jimmy Page setup (with Pearly Gates and Jazz pups), which I am very comfortable with, it has a lot of good tonal options available, and I can always leave the push/pull pots alone and it operates like a normal LP.

Re: 'Ultimate' mad professor wiring?

I think a push/pull to engage the bass roll-off will do. I want this control, but don't want to lose standard tone control, so that will have to suffice!

Now... I don't suppose anyone can suggest a wiring scheme to my poor guitar tech?

* 50s wiring (with cavity switch to revert to modern)
* standard volume controls
* standard 3-way pup selector
* neck tone p/p OOP
* bridge tone p/p bass roll-off

Re bass roll-off, I see two suggestions:

* https://forum.seymourduncan.com/showthread.php?330264-Short-bass-roll-off-contour-video

Are they... different? Could I do this push/pull?

Re: 'Ultimate' mad professor wiring?

Functionality they are the same and you could do it with a trim pot if you want to tweak the mix, or try various cap values directly inline with only a switch. Considering you are experimenting, I would do the trim pot and switch out caps.

Thanks... Do you have any idea what that 1M resistor does?

Re: 'Ultimate' mad professor wiring?

Would it be feasible to add this as a p/p option to the neck tone?

Yep, standard push pull...
The resister is for tuning the circuit, but not sure if its a frequency thing or impacts vol / tapper... We put alligator clips in the cavity to drop in different caps and have done most without the resister but they are all different.

Alligator clips are good. I personally use terminal strip.

For a strat-style guitar you'd want wires to hang out of the cavity with those. So you can switch them without removing pickguard.

If you don't want to dismantle your guitar for experimenting with caps, roll open the jack from lead and connect the cap, or whatever else you want to try, there between hot and ground. Works well for quick try out.

Cool idea, thanks!

Re: 'Ultimate' mad professor wiring?

So the Seths are in the shop getting fitted as we speak...

I ended up with 50's wiring, p/p OOP on bridge tone, p/p to bass roll-off on neck tone. Volumes staying stock but changing to p/p pots for the future.

...and the guitar tech suggested I might like to install a hinge on the backplate for all the future fiddling...

Re: 'Ultimate' mad professor wiring?

I am actually thinking of putting a simple bass roll-off circuit in a project box and attaching to my strap: just a pot, cap, and two jacks. So... basically a simple eq box
