There were no competitors' models anytime during the 13 years that the product was made, and none have appeared since we discontinued it in early 2016.  Thank you for your understanding.

Replacement Keyboard/Speaker Stand Knobs (Thumbscrews)

These threaded knobs fit Ultimate Support, and other keyboard and speaker stands -- any piece of gear that uses a 1/4"-20 threaded knob.  They're made of a durable acetal plastic which resists scratches and damage from dropping.  Don't throw that stand out -- replace the knobs and it'll work like new again!

Note:  These knobs have stainless steel threads, and may strip if overtighted in a standard steel nut.  We supply a matching stainless steel nut, and we highly recommend that you replace the existing nut with the included part.


Set of 2 Black Knobs/Nuts $8.00
  Set of 5 Knobs/Nuts $17.50

Replacement Slider Knobs


These are exact replacement slider knobs for ones used on Mackie, Soundcraft, and other mixers, perfect for replacing the one never came with your used gear.  It's also useful to swap out some of the one-color set on a mixer to make it easier to find things on stage; use the colors to define a vocal grouping, or the drum channels, for example. We sell four colors:  black with white stripe, red with white stripe, grey with white stripe, and white with black stripe.

The knobs are available in two shaft styles: 1mm x 8mm (blue border, below), which fit Alps 100mm faders used on Mackie studio consoles, as well as Behringer and other equipment; and 1mm x 4mm (red border), which fit Mackie CR/CFX and Soundcraft mixers with 60mm Alps faders, as well as CME Keyboards, and many other brands.

Note:  Some colors are only available in 1mm x 4mm.  How to modify an "M" slider into the "K" style.

These knobs are no longer generally available in the US.  If you want genuine knobs to match your Mackie CR/SR/CFX mixers, these are the ones.


K-tang (8mm) Knob $1.35
Red          ONLY 3 LEFT

  M-tang (4mm) Knob $1.35


NOTE:  Most of the slider styles we sell use the "M" mounting tang style, as seen below, the most popular style.  The ones marked as "8mm" use the "K" mounting tang style.  (As a general rule, 60mm faders have an M tang, and 100mm faders have a K tang.)  As long as your sliders DO NOT have a Penny and Giles 'T-top,' then one of our knob styles will probably fit.

NOTE:  We do not carry the "P" style knobs, nor do we know where to get them.



Korg Synth Knob $3.00


Vintage Korg Synth Knobs

These are genuine Korg knobs from the mid-80s, and will replace broken or missing ones on the PolySix™, MonoPoly™, and Poly 800™ synths, as well as some Korg drum machines and effects.  The are press-on style, designed to fit a splined shaft.

Note:  These knobs are sold individually, not in groups of six.


IEC Power Cords

These cords have the regular three-pin AC plug on one end, and an IEC-style plug on the other.  IEC-style plugs are used by Behringer, Digitech, DOD, Korg, Mackie, Peavey, and others -- just about anyone who still puts the power supply inside the gear. At AshbySolutions.com, we sell only two styles of AC power cords: the longest and shortest ones we can find!  (Hey, you can get a 6-foot cord just about anywhere.)

Why you NEED a longer power cord --

  • Because there's no such thing as an extension cord that's "long enough."
  • There always seems to be one less outlet on your side of the stage than you need.
  • That power strip in your rack is great, but they always make you put it just a little too far from where you stand.

Our Long Power Cord is 15 feet long. That's right -- 4-1/2 meters and change!  Chances are, it'll reach from your end of things to whatever you need to plug into.  It's UL approved, and comes in only one color: black -- just to make Henry Ford proud.

Note:  These long cords are nice and thick, so they're heavy, and shipping costs are higher than most items in this category.

$9.00 or 2/$17.00 (+ S/H)  


OK, so then why do you need a shorter cord?

  • Connecting gear inside a rack.  Cables are heavy to lug around, and they add to the clutter inside the box.
  • All that stuff sitting on a table in your studio, plugged into an outlet box.

Our Short Power Cord is only three feet long (0,9m).  It's also UL approved, and comes in Mr. Ford's favorite color, just like its big brother.

$4.75 or 3/$13.50 (+ S/H)  


So, what's this "Xtra-Short" one for?

Sometimes the gear in your rack is sitting so close to the power strip that it almost doesn't need a power cord.  So, we're offering buyers a choice:  3-foot for those places where the power cord isn't exactly next to the outlet, and 1-foot for when it is.  If you can live with a very short cord, you'll save even more space and weight.  It's also UL approved, and comes in classic black -- why buck a trend here?

  • That AC adapter that sits on the floor, right next to your power strip. The one that you always trip over, because the cord's in the way.
  • All that stuff sitting on a table in your studio, plugged into an outlet box.
$4.25 or 3/$12.00 (+ S/H)  
Piggyback Power Cords  
This is a great idea!  As rack gear gets smaller and smaller, more stuff fits in the same rack.  15-20 years ago, an 8U rack was good for maybe 4-5 items. today, power amps are 2U or less, and half-rack modules are everywhere; it's possible to put 10+ modules and amps in that same space.  Well, guess what?  The built-in power center still only has 5-6 outlets.

Enter these piggyback IEC power cords.  Simply attach one of them to the first rack module, then connect another power cord to the outlet in the back -- and save a couple of extra outlets to use at the gig!  They're made with 14AWG wire, so current handling isn't an issue.  They are available in 2-foot lengths.

2 Foot Piggyback Cord
$8.25 (+ S/H)



2-pin Power Cords

We started carrying these power cords as spares for the Ventilator, but heck -- they fit all kinds of other gear, too.  The Virus TI KB uses one.  So do the Nord Electro and Stage, and the power supply to the V-Machine.  The list goes on and on.

You know you're going to break or lose one sometime.  Why not have a spare or two?

Spare 5-foot power cord    $4
