What to do with an unused hole...

[Groove Doctor]

Electric pencil sharpener?

Are you trying to make a point?

 

[Need Gigs]

Sadowsky VTC

I would install a red push button connected to nothing and label it, “Do Not Press”

Like the one in all those space/si-fi movies that if it gets pushed the universe gets blown up? Digging it!

Madison's designed this harness to unlock the true potential of your guitar. This is a passive unit -no battery- and will work with any passive pickup. The controls offers independent Volume and Tone controls for both pickups. This allows you to blend both volumes and tones at any rate together. The third knob is a center detent boost. 1-5 is a treble boost (eliminates compression) 5-10 is a bass boost. The mini toggle switch is used to invert the phasing of the pickups. Overall we wanted to design the ultimate Jazz bass harness bass players can use.

Again, i have to ask... Why would we want to invert phase?

What was the old layout and what is your current pre modded layout?

Dangerous question, but I don't want to run afoul of TB rules.

Any port in a storm. How's that?

 

[39-Bassist]

leave it alone and order a replacement pg without the hole from WD Music...
Just my thoughts

What was the old layout and what is your current pre modded layout?

Original layout was V/V/Treble/Bass with an active-passive toggle. The current Sadowsky onboard preamp is Volume/Blend/Passive Tone (VTC) that is also push-pull active-passive/Stacked active treble-bass. It now has an open spot as the original active-passive toggle is no longer needed.

 

[TrevorOfDoom]

series/parallel switch. seriously.

 

[oldskoolskatedad]

Second output. Wire the thing like an ES-345/355, so that you can run each pickup completely independently to a different amp, or run both in parallel out a single jack, with a stereo to mono adapter.

Excellent! Stereo output is a great idea! I'm a little embarrassed it hadn't occurred to me as I already have a Ric-o-sound rig

 

[pappabass]

Switch for Flux capacitor to 10x the output.

I converted a bass from active to passive, went from four controls to just three so there was an empty hole so I just put a sticker over it.

I could of put a black piece of electrical tape over the hole too because my bass is black. Also gluing a dummy control knob over the hole is an option too if you're that cavalier.

Simple, because it gives me a tone I can't get otherwise.
Is there something wrong with Madison's UJ controll plate that I don't know about?
Is there something wrong with the tone of my Dean Exotica that I can't hear? Phase switch engaged here. In phase doesn't sound anywhere near this good.

I have a utility pedal with a invert phase switch. I suppose in those rare occasions where you have some keys or other instrument in the same sonic space and for some reason they are cancelling out with you, a flip of phase can sometimes reinforce both when playing together.

 

[nilorius]

You can just make a not working, the same design and leave it alone.

 

[Coolhandjjl]

Ask Chrissy:

I’d forgot what ferocious intensity they had.

 

[Lownote38]

I would put a dummy volume knob there for when sound people tell you to turn down.

You can buy black plastic plugs at any hardware store that will fit perfectly and become almost unnoticeable. I do this whenever I reconfigure an instrument and end up with an extra hole or 2 for switches.
