JackPot Potentiometer

About This Item

This combo pot and rotary switch bypasses your instrument's volume and tone controls. Play full throttle, with the pickup wired directly to the output jack, for a broader signal and enhanced highs.

"Take the muffler off your electric guitar!"
—Ned Steinberger, designer

When wired into your guitar (rewiring of tone controls may be required), this control removes the load of the pots. Think of it as a knob that goes from 0-10, plus a switch to 11—there's an actual click!

The JackPot's rotary switch clicks on when the knob reaches full rotation. The open switch lifts the ground to the pot, eliminating the load on the pickups and letting the full signal reach the output jack. When the knob is rotated counterclockwise, the ground to the pot is reconnected, so the pot returns to standard operation.

"On my Tele I get a brighter, more aggressive sound that is more sensitive to my picking style and attack!"
—Casey Davis, guitarist and StewMac customer service rep

    Why do you want it?
  • With the JackPot you can play full on, with the pickups wired directly to the output jack. You'll still have a trusty volume knob to back off instantly to a lower level when needed.
  • The JackPot produces a stronger signal level, greater warmth, more intensity.
  • On typical instrument wiring, when the volume knob is maxed out, there is still a portion of the signal that bleeds to ground. The output level never reaches the full level the pickup would achieve if it were wired directly to the output jack.

Which pot value should you choose?
500K pots are standard controls for humbuckers, and 250Ks are usually used for single-coil pickups. A 250K gives a slightly warmer tone than a 500K, and bleeds off some of the high frequencies to ground. A 1-meg pot bleeds off even less than a 500K.

1-meg pots are also ideal for piezo pickups, as the ultra high impedance piezo element is more adversely effected by conventional, lower-value pots than magnetic pickups.

Replacement Mounting Nuts and Lock Washers are also available.

Needs improvement.

I really like this idea, and the design is okay, it just feels a little lightweight. I'd like to see this in a full-sized version, with a more definite feel to the direct-out position.

Great idea, very poorly executed.

By
(Customer's Reviews)


Bought this with high hopes for a very cool mod on an S-S-H strat project. Not impressed AT ALL. The lugs are TINY, making wiring a pain when connecting the grounds, and the pot itself is very small and delicate. Also, it has a VERY fast taper with full volume in the 7 to 8 range on your dial, with activation of the direct out at 10. Not a huge deal, but annoying as the detent is not really a click, just a tiny bit of tactile resistance separating the two modes. Also, while the increase in highs is audible, I found it to be somewhat negligible. Unless you have a really discerning ear, I don't think this mod (especially with this pot) will produce the effect you are looking for. If you really want to do this mod, try a push-pull pot, or DPDT switch, or experiment with some no-load pots. There are plenty of great wiring diagrams online, and you will get the same effect without sacrificing the integrity of your volume pot. Until this pot is improved, trust me, it's NOT worth the hassle.

JACKPOT!

I bought this 1 meg pot for my customized GODIN 5th Ave. It has a Johnny Smith ceramic humbucker-floater and a P.U.T.W. transducer under the bridge foot. I love "my little mongrel" and this potentiometer made my "experiment in-tone" equisite! BE aware; this pot does have a quicker rise in db and a slightly less rotational degree but it works for me! The hot-switch at the end of the twist sends signal sans variable resistance; BLUES!

More options than you are used to with a volume pot.

By

More than giving a clean line directly to the output jack the jackpot offers a way to have a tonal preset just below the threshold of the direct out. So you can back off on the volume just a bit and all of your tone controls cut back in. I am quite taken with the sound of the pick ups and no tone controls.

Awesome idea, poor implementation

I bought this just because I hate when I roll my volume up to play and start wondering why my tone is muddy only to notice I didn't roll it all the way up. Having a click to tell me it's all the way sounded perfect.

Downside of this pot for me is the fact that it's range (how far the pot turns to go 0-10) is a good chunk smaller than normal pots. It goes from 0-10 in the time a normal pot goes from 0-7.5, with the full click it goes to about 8.5. Makes it more difficult to use if you use your volume knob for volume dynamic sensitive stuff and sucks that your numbered knobs won't line up with it. Had it had a normal range, this would've been my dream pot.

Nice in theory...

By

The pot was not smooth, the detent and transition to bypass. I like this in theory, but in reality I'll stick to a 1 Meg vol and no load tone pot for that "all in" sound.

Simple but effective

I've used these on a couple of showcase guitars to demonstrate some fancy wiring options. Really well made, intuitive to use and opens up the tone of your instrument nicely. On a humbucker equipped Jaguar style guitar, I can get a nicely pronounced Tele style twang. It also works really well if you "park" your tone at a favourite position and then use the volume knob to toggle between settings instantly.

I love this thing.

Just put it in a client's guitar, and I thing it's great. Unlike the trad blower switch that just works on the bridge pickup, this one works on all. Good volume and treble boost. Very well made. I'm buying some for my personal instruments.

Fantastic!

I think the previous reviewer missed the whole point of these pots. The only way to get direct injection from the pup is to lift the ground and eliminate the tone pot (high pass bleed to ground). I installed this pot in my latest Tele build, complete with Fender Texas Custom pups, 4-way switching, and a push-pull for tone and diode rectifier circuit. This guitar is a tone machine! Great invention! Upgrading my SG build with these pots, and will be standard in all future builds. . .

Great idea, Poor implementation

These may work if you are using 24 gauge modern wires, but if you use vintage cloth wire only one wire will fit through the tiny holes. I installed this on two Telecasters with 4 way switches and a Stratocaster. If you look at both wiring diagrams they use the same lug for different things and I could not get the Tele diagram to work except for the neck pickup. The Strat diagram works but a vintage Strat needs a tone pot when soloing. I would give it two stars if Steinberger's website had a diagram that correctly labeled all the lugs, but I couldn't find anything except the diagrams here and they are rather random. This needs to be done with a full sized pot and full sized tabs!
