Hello, I'm a newbie here and looking forward to being part of the group.
Has anyone wired the Epi Nighthawk for both humbuckers together? I would like to try this but don't care to change the existing setup.
Can this be done with a mini toggle of sort? and how would you go about it? Thanks for looking... hope to hear from some Nighthawk fans and others.

I don't have a specific answer for you, but I'm sure the modifcation is possible. But that guitar already has such a wide number of pickup selection options that---speaking from my own wiring-mod experience---any additional tones you might gain won't be worth the additional complexity in your control lay-out.
But that really is something personal to the individual guitar-player. I have done rather extenstive pickup switching mod, with a bunch of different switches, and, in the end I've usually found that I perfered simplicity.
One of those B.C. Rich models with the toggles and rotary switch and knobs would be my nightmare. I was recently playing a Squier Jazzmaster, and although I liked the guitar, all those switches left me a bit confused.

Hi Steve and welcome.
Let me preface this by saying I dont have one of these guitars, but I have done a fair bit of wiring, so if someone else has first had knowledge with your wiring, I would listen to them. That said, I think the wiring would be a simple mod, but the implementation might be a lot of work. If you've ever heard of a blender mod, this mod would be similar. What the blender mod does (typically performed on a strat) is to take one of the tone controls and make it a master tone, and then with the (now) spare tone control you wire it to fade the neck pickup into the bridge, or the bridge into the neck depending on switch position. This works in all switch positions except 3 because position 3 is just the middle pickup. The wiring for this is such that the pot controls the resistance between the two hot wires for the neck and bridge. In your case, if all you want to do is toggle them to be either fully blended, or fully isolated, all you have to do is put in a switch that shorts those two wires (where they meet at the switch) when it’s flicked, and when the switch is flicked back, they won’t be connected anymore so the guitar will function the way it does now. You could test this to see if you would like the tone by just jumpering between those contacts on the switch and playing the guitar, then if you like it, the real work begins with how/where you would mount the switch. Hope this helps.

Hey Sparky, question on the blend pot set up you spoke of. I had a few laying around and put an ohm meter on them to read. Nothing moves till you get close to 3/4 of the rotation and then you you see the gradual movement you would expect.
That does not seem normal in any case. Am I testing wrong? Or is this the nature of an audio pot and I need to look at a liner pot? Thanks again, and anyone else, please feel free to jump in.

There are several different "tapers" available in pots. A linear taper increases the resistance linearly as you turn the knob. So with the shaft turned all the way counter clockwise, you should read zero, When the shaft has turned half of it's full range, it should read half of the total pot resistance (250k on a 500k pot for example), and when it's all the way up, you should read 500k if it's a 500 k pot. Audio taper, or log taper plots, ramp up slowly at first, then come on strong at the end (as you have seen). At the full off and full on positions they will read the same, but at the halfway position, they should only read about 10% of the total resistance of 50k on a 500 k pot. The reason log tapers are useful in audio applications is because the human ear doesn't really respond in a linear way. So both tapers will work for volume or tone controls, but how they respond as you turn them is what varies. Personally I like linear vol pots and audio taper pots for tone controls. I know other folks who like audio taper on volume because it gives more sensitivity at one end of the dial. In the end it's really just a matter of preference. But try the audio taper pot in your application before you buy another taper, because it's not intuitively obvious how it will sound just based on the resistances you measure. When I did my blender mod for example, I tried linear, audio, and reverse audio taper pots, and it turned out the reverse audio taper produced the smoothest linear sounding blend.

Here is a link to a diagram if you want to use the pot. In that case you wouldn't need the push/pull switch. 10 on the control would be no blend, and 0 would be full blend. If you want 0 to be no blend (as I did) you would use the other outer lug and use a reverse audio taper pot for a nice gradual blend. I love my blender on my strat, but not sure I would do it if I had to drill holes. Good luck!

Hey Sparky, thanks once again. This thing has my head spinning to some sort, he he..
I'm not the brightest person when it comes to this stuff, but I muck my way through somehow. ( or try )
This is what I ordered, it seems to fit the bill with the simple jump lead program without a toggle, and works like my 5 way is set up. Let me know what you think. Steve.. PS: they make no mention as to whether the pot needs a ground?
04-13-2013 09:26 AM
Well electrically it looks like it would work. The only ground would be to connect to the back of the pot, but not to any of the lugs. The only problems I can see with using it are, the taper (probably OK but it would be nice to see it spelled out), and the length of the bushing, which they say is 1/4 inch. This size bushing is good for mounting on a pick guard, but if you are planning on drilling a hole in your top and mounting it that way, I would think it would need to be longer. You could measure one of your other pots in the nighthawk for the exact size. Here is a good place to get pots. I found lots of types and their shipping is reasonable. BTW any old pot will work for the blender mod, but the one you listed is nice because its a no-load pot. However, if the bushing size doesn't work out, you might find a better match there.
