What is VHUB2?
It's a simple, stand-alone wiring device designed for Gibson-style control configurations, that installs into your guitar in place of the neck volume control. Connect your existing pots (the bridge volume, plus one or two tone controls) to the VHUB using quick, convenient screw-down terminals. Same with your jack and switch. Finally, make your pickup connections, and you're done.
Don't have existing components? Want to upgrade your controls in an imported guitar, or add functionality, such as push/pull pots to split humbuckers? Then consider one of our VHUB2 Completion Kits, which give you all of the components needed to complete the job.
What's it do?
While your other controls (pots/jack/switch) will need to have wires soldered to them, they'll connect quickly and easily to the VHUB with screw-down terminals (screwdriver included). So if you already have these components in your Gibson-style guitar, then you should be able to connect them to VHUB2 with no soldering. And, once the unit is installed, it lends itself to maniacal...
That's right, to maniacal pickup swapping. Pickup changes will become a breeze, so you tinkerers will have the easiest time ever swapping out your pickups. Minutes, even. So go buy a bunch of pickups, and tone-geek to your heart's content. We won't tell.
Built-in, Bypass-able Treble Bleed
Traditional guitars have a problem with their volume controls: Lowering your volume also produces a reduction in treble. So if you like to roll your volume to, say, 5, then you'll also be experiencing a fairly pronounced tonal shift, not just a volume reduction. The treble goes away, and the tone can sound dull. Treble-bleed circuits are small resistor/capacitor networks (RC networks) that pretty effectively combat this phenomenon, and we feel that they do so in a pretty non-intrusive way, but opinions vary. In any case, the VHUB has two of these built-in - one for each volume control - and you can enable one or both with the flick of a switch. So you can try 'em, and see if you like 'em. They're very, very popular, but there's another thing you can do to combat treble-loss, and that's accomplished with...
Modern wiring is where you would (optionally) enable the treble-bleed networks. But you can also try vintage-wiring (sans treble-bleeds), which feeds the tone controls from the outputs of the volume controls, rather than their inputs. Some prefer this, though it does make the volume and tone controls somewhat interactive. But with VHUB it's quick and easy to try - a flick of a switch or two - so you can experiment!
By the way, when we talk about flicking switches, we're referring to the little DIP switch on the VHUB's top surface. Those little switches make it a cinch to configure the VHUB the way you like it, and to re-configure it to try something else. Ha ha, it's a cinch, Biff, just like in Pleasantville!
Independent Volume Controls
With normal Gibson wiring, if you have the pickup-selector in the middle position (both pickups on), rolling either volume down all the way turns the guitar completely off! We never liked this. A Jazz Bass doesn't work this way, and Gibson guitars don't need to either. We've set the VHUB2 up so that rolling either volume control down only affects that pickup. Makes sense to us (that Leo Fender was no dummy).
Want configurable tone controls? Our THUB units connect solderlessly to the VHUB2, making installation super quick and easy. And each one has four capacitors built in, so you can dial them in the way you like. Choosing different cap values affects the amount of treble that's being rolled off, so you can go from subtle to excessive by flicking those little switches. Turn on one or more than one, for capacitance values that basically cover the gamut used by the electric guitar industry for the last 60 years (.010µF to .094µF).
Now we're talking. Many (most?) humbuckers now come with 4-conductor wiring so that you can split them. You make one of the two coils go away, and the remaining single-coil sounds reminiscent of Fender-style guitars. And that's a beautiful thing, believe us. VHUB2 supports coil splitting, but you'll need a switch or two (two if you want to be able to split the humbuckers independently). Our Completion Kit with push/pull pots would be just the thing!
Supports VVT or VVTT
Most THUB2 users are going to have 2 tone controls. But not all guitars do; some, like Gibson's Flying V and Explorer, use only a single tone control. No sweat, VHUB2 is happy supporting one tone or two.
1/2" Pot Bushing-Length
Our Gibson pots have 1/2" bushing lengths (that's the threaded part). Our experience with Gibson guitars is that Gibson aims for 1/4" thickness of the guitar's top at the control hole locations. We've heard tales of thicker tops, but have not seen anything much thicker than this. So we order our pots with 1/2" bushing lengths so that the bushing will be long enough to install an inner nut, then a lockwasher, then pass through the guitar's top, then through an outer flat washer, and finally, still have sufficient threads showing to get a second nut on the outside.
This allows you to A) use the appropriate washers, because you would really like to have a lockwasher on the inside, and a flat washer on the outside; and B) be able to adjust how much of the threads protrude from the face of the guitar - accomplished by having a nut on both the inside and the outside - so that you can minimize the height of the pot shaft above the guitar's face, and consequently get the knobs as close to the face of the guitar as possible. Every tech has seen guitars with the knobs sticking up 3/8" off the face of the guitar. Please, don't embarrass your guitar like this. It's not honorable.
We want this unit to fit into many guitar cavities. Hence: Small. It should fit.
So there you go. That is one full-featured little device, and for chump change. You should probably buy 4 or 5, you'll feel better about yourself. And we'll feel better about yourself too!
