Hey Guys,
I have an Ovation Double Neck guitar, it has 2 pickups, one for each neck, 1 preamp and 1 output. The pickups go to a 3 way switch that controls which pickup's signal goes to the preamp (or combines them), then of course the preamp goes to the output.
What I want to do is install 2 more outputs on the guitar, 1 for each neck's pickup so that I can pan the necks to either side in stereo. I would bypass the preamp entirely and send a passive signal to each output and then go through 2 different LR Baggs Para DIs to boost each signal. But I don't want that for every show and I would like to keep the option of using the original preamp and output.
So here's what I've done so far:
I sent each pickup to a separate on-on switch (each switch has 6 prongs) and wired the hot output and the ground to their respective middle prongs, sent a hot out and a ground to the preamp switch on one pair of prongs (so that will ultimately go to the original guitar output where both necks come through) and with the other pair I sent a hot output and a ground to a new jack.
This way I can flick those switches and plug into the original output and have it work like it always has, or flick them the other way and plug into the 2 new outputs and hear myself in stereo-and it works, yay.
However, I'm getting a pretty substantial hum, and I think it's probably a grounding problem. Would you guys have wired the way I described in order to accomplish this? I haven't worked much on acoustic guitar electronics, but do transducer pickups hum the way single coils do on an electric guitar? If so, why is the guitar quiet when I plug into the original preamp? Is it the switch?
Also, one reason I believe it's a grounding issue is because I use a no-pop cable, and when I lift the button to kill the circuit after I use it with this setup, I hear a pop. What's up with that?
I've tried using a direct box with a ground lift on it and it did nothing.
Any ideas guys? Thanks so much,
