The polarity switch makes it work with any brand, not just one
A 6.35 mm (0.25 in) plug, which is what nearly every keyboard pedal socket uses
A light pedal can slide on a smooth floor while playing
Best for: Any keyboard or controller that did not come with a pedal — which is most of them.
Almost every digital piano and keyboard has a pedal socket, and almost none of them include a pedal. This is the part that fills the gap, and the reason to choose this one over the cheapest available is the small switch on its body.
Sustain pedals come in two polarities, and manufacturers disagree about which is correct. Plug the wrong one in and the instrument sustains permanently until you press the pedal, at which point it stops — behavior that reads as a fault and sends people to support forums.
A polarity switch removes the question. It works with Casio, Yamaha, Roland, Alesis and controllers alike, which is why it is listed against so many instruments in this catalog.
The one practical complaint about light pedals is that they travel on hard floors. A strip of non-slip mat under it is a five-minute fix.
The questions players ask
My keyboard sustains all the time until I press the pedal. Is it broken?
No — the pedal polarity is reversed. Manufacturers use opposite conventions, and a pedal wired the other way round produces exactly this behavior. Flip the polarity switch on this pedal and it corrects instantly.
Is a sustain pedal the same as a damper pedal?
Yes, for this purpose. On an acoustic piano it lifts the dampers off the strings; on a digital instrument it does the equivalent in software. Some instruments also support half-pedalling, which needs a continuous pedal rather than a footswitch.
The MS1078 with wheels and a second tier: 250 lb on the base and a separately published 60 lb on the top, with the tier adjusting from 19.5 to 35.5 inches wide and stated to fit 1.25-inch square tubing.
Contents
MS1078 Z-frame, MS1118 second tier and wheels — published as one reference, KIT-MS1078-MS1118
Base rating
250 lb stated (maker’s bullet)
Tier rating
60 lb stated, separately. The only second-tier capacity published on this shelf, and the only listing here that rates two surfaces (maker’s bullet)
Tier adjustment
Width 19.5 to 35.5 in in 2 in increments, height 22.5 to 35.5 in in 1.5 in increments, with adjustable angle (maker’s bullet)
Tube section
Stated to fit any keyboard stand with 1.25 in square tubing, including this maker’s MS1078, MS1080, MS1084 and MS1085. The only tube section published on this shelf, and the figure that decides whether a tier will mount (maker’s bullet)
Wheels
Yes. Three of the twelve stands on this shelf have wheels (from the title)
Retention
Anchoring straps, adjustable feet, anti-skid foam pads and a headphone hook (maker’s bullet)
Stated additions
The tier is stated to take a keyboard, a synth or a laptop, or attachments for a microphone, monitors or a tablet (maker’s bullet)
Manufacturer reference
KIT-MS1078-MS1118
Weight
13,812 g (487.2 oz) in the product record — the heaviest figure on this shelf, for a stand, a tier and a set of wheels together

Two surfaces with two published ratings, where no other stand here rates more than one
Publishes the 1.25 in tube section, which is the figure that decides what a tier will fit
The tier is rated 60 lb, so a second weighted 88-key piano does not belong on it
Best for: Two keyboards, or a keyboard and a laptop, on one footprint that rolls.
A heavy-duty Z-frame rated at 250 lb that publishes how it adjusts rather than just that it does: height in 1.25-inch steps, width in 2-inch steps, with two anchoring straps and a headphone hook in the box.
Load rating
250 lb stated, for the heaviest instruments. Four of the twelve stands on this shelf publish this figure; one publishes 100 lb; seven publish none (maker’s bullet)
Height
22.5 to 33.5 in, in 1.25 in increments — the finest published step on this shelf (maker’s bullet)
Width
22.5 to 33.5 in, in 2 in increments (maker’s bullet)
Retention
Two anchoring straps that attach the keyboard to the stand, plus four adjustable feet and anti-skid foam pads (maker’s bullet)
Included
A headphone hook. Four of the twelve items on this shelf have one, and all four are from this maker (maker’s bullet)
Stated fit
54 to 88 keys, and stated for DJ mixers, turntables, synths and MIDI keyboards as well (from the title and maker’s bullet)
Frame
Z-style, stated less likely to tip than an X-style stand — which is the argument another page on this shelf makes in its own words (maker’s bullet)
Setup
Stated under a minute to set up or break down, packing flat for transport (maker’s bullet)
Wheels
None. The same maker sells this stand with wheels as MS1080, two dollars dearer — and that listing publishes a 1.5 in height step rather than 1.25 in

Weight
7,000 g (246.9 oz) in the product record, which is 7.0 kg (15.4 lb) exactly — a shipping figure. Nothing here is ranked on it

A published 250 lb rating, which answers the question the X-frame page on this shelf has to leave open
The finest published height step here at 1.25 in, so the right setting is reachable
Two dollars buys the same stand with wheels from the same maker
Best for: A heavy weighted 88-key piano that needs a stand with a number on it.
The MS1078 on wheels, at two dollars more: the same 250 lb rating, the same straps and headphone hook, the same width steps — and a height step of 1.5 inches rather than 1.25.
Wheels
Yes. Three of the twelve stands on this shelf have wheels, at $44.99, $79.99 and $159.99 (from the title)
Load rating
250 lb stated — the only wheeled stand on this shelf that publishes a capacity (maker’s bullet)
Height
22.5 to 33.5 in, in 1.5 in increments. The same maker’s MS1078, two dollars cheaper and without wheels, publishes 1.25 in (maker’s bullet)
Width
22.5 to 33.5 in, in 2 in increments — identical to the MS1078 (maker’s bullet)
Retention
Two anchoring straps, four adjustable feet and anti-skid foam pads (maker’s bullet)
Included
A headphone hook (maker’s bullet)
Stated fit
54 to 88 keys, and stated for DJ mixers, turntables, synths and MIDI keyboards (from the title and maker’s bullet)
Wheel locks
Liquid Stands puts nothing in writing on this. The cheapest wheeled stand on this shelf states locking wheels explicitly

MS1080
Weight
7,310 g (257.9 oz) in the product record, against 7,000 g (246.9 oz) for the same stand without wheels

EAN
0070361071537
The only wheeled stand on this shelf that publishes a load rating, and it is 250 lb
Two dollars over the fixed version, which is less than the castors would cost separately
The height step is 1.5 in, coarser than the 1.25 in of the same maker’s cheaper stand
Best for: A heavy 88-key piano that has to cross a hard floor and then stand still under weight.
Fifty one-inch foam panels with triangular grooves, 300 double-sided adhesive squares supplied, and the only fire claim on this shelf — which on foam glued to a bedroom wall is the line that matters.
Quantity and size
50 panels at 1 × 12 × 12 in — the largest quantity on this shelf
Profile
Triangular grooves, which Focusound states absorb noise better than a flat face
Adhesive
300 double-sided adhesive squares supplied free — six per panel
Fire
Focusound states strong fire resistance and that the foam stops burning to prevent a hidden fire hazard — the only fire claim on this shelf
Material
High-density foam. Focusound states that if it does not return to shape it can be soaked in water and air-dried
Thickness
1 in — 2.5 cm. One panel on this shelf publishes 5 cm (2 in), and its page notes thickness is what reaches lower
Absorption
Focusound publishes no NRC figure. No panel on this shelf publishes one
Air permeability
Stated as good, alongside the fire resistance
Coverage
50 square feet in total

Fifty panels, the most on this shelf, with 300 adhesive squares included — six per panel
The only panel here to publish anything about fire, and it says the foam stops burning
One inch of foam treats echo and not bass, as the page for another panel here states
Best for: Covering a lot of wall at once, where the fire claim and the adhesive count matter as much as the foam.
A metal grille rather than mesh, with slats angled to send air downward instead of scattering it — on a 12.4-inch gooseneck, and the only filter here to publish what its clamp will grip.
Filter
A durable metal grille whose angled slats divert air downward — a different mechanism from mesh, which scatters it
Gooseneck
12.4 in — the only gooseneck length published on this shelf
Clamp capacity
Mounts to most microphone stands or boom shafts up to 18 mm (0.71 in) in diameter — the only clamp figure on this shelf
Material
Metal. One filter here is nylon mesh, one is foam, one layers mesh, metal and foam, and one offers all three as separate filters
Stated purpose
Shielding recordings from popping while preserving vocal quality, for podcasts, broadcast, streaming and vocals
Layers
Gator puts nothing in writing on this. A metal grille is a single structure rather than a stack
Diameter
Gator puts nothing in writing on this. One filter here publishes 6 in
Cleaning
Gator puts nothing in writing on this, though metal is the one material here that can be wiped
Weight
113 g (4 oz) in the product record. One filter here is heavier still at 209 g (7.4 oz), and the three-filter package weighs 980 g (34.6 oz)

The only filter here that publishes what its clamp will grip — shafts up to 18 mm (0.71 in)
The only published gooseneck length, at 12.4 inches
The most expensive filter on this shelf, at six times the cheapest
Best for: A desk arm whose shaft has been measured, where the filter needs wiping rather than replacing.
