Big Knob controller in Boing Boing Bazaar


Tristan Shone's "Big Knob" is exactly that: a giant knob for use as a controller in live music performance with a removable detent so it can "click" or turn smoothly. You can buy one in the Makers Market / Boing Boing Bazaar for $225.

This simple device is a heavy-duty CNC machined black anodized knob for use with your expression port on any midi/usb keyboard controller. Simply plug into your expression port and immediately have a 0-128 mappable control knob for use with Ableton Live, Reason, etc.

Currently there are 10 spring loaded detente positions and a hard stop for quantized physical snapping, however by removing the 1-inch chromed steel ball bearing and spring, you can create a smooth position knob controller. The detente disc is made from self-lubricating Delrin which both supports the potentiometer and creates a smooth snap in with the chrome spring loaded ball bearing.

The stainless steel frame is adjustable and clamps onto either your keyboard or table.

Big Knob: $225


  1. Hey guys, just a heads up. Just because a joke is easy to make… doesn’t mean it’s not funny.

    he he he… big knob.

  2. I’m not a musician so i have no idea what this sort of stuff usually sells for so i’m speaking out of general ignorance. But holy hell 225 bucks sounds a lot for a knob controller.

    Seems rather cool looking, though it’d be nice to see it in a nice enclosure of sorts, unless there’s a good reason it’s set on a bracket looking thing.

  3. that absolutely RULES! I’m trying to justify buying one right now, just can’t come up with anything.

  4. I want one. I have no idea what I’d do with it. Maybe put it next to a big shiny red button.

  5. i imagine the cost is due to the fact that each is hand-crafted. mmm… hand-crafted knobs…

  6. “Currently there are 10 spring loaded detente positions”

    I have the same knob, but mine has 11 spring-loaded detente positions. You see… 11… it’s one better.

  7. Oh, man… that big knob is right up my alley. (sorry)

    Seriously – DO WANT, but it is a little out of my price range at the moment.

  8. @ Anon 13:

    It’s for knob-tweakers to tweak, while standing hunched over folding table covered with home-made electronics, delay pedals and MANY, MANY wires.

    (I had a boyfriend once who took me to many “Noise” “Shows”)

  9. I’m having a hard time resisting my own big-knob gag!

    (see what I did there!)

    Having said that. Hercules Muse is a $40 big knobbed USB device with its own 5.1 sound card built in.

  10. How about just $150 for 24 endless rotary controllers that you can “Simply plug into your expression port and immediately have a 0..128 mappable control knob for use with Ableton Live, Reason, etc.” ….–BEHBCR2000

    And if you prefer faders instead:–BEHBCF2000

    I’m no fan of behringer, but these are actually incredibly great little units. You can use them with free software like too.

  11. That knob is kind of big, but not really big. I’ve seen a couple of really big knobs, and they were bigger than that one, bigger than that big knob.

  12. I had a big knob once. But now I’m old and I don’t always remember where I put things.
