Instrument accessories can look comparable at a glance, but a sustain pedal, a workstation kit, a violin accessory set, and an audio snake solve very different problems. Start with the instrument or connection you need to support, then use the listed price as a secondary decision point. This group ranges from USD 25.22 to USD 114.73, with the violin kit at the low end and the STX807 cable at the high end.
Quick take
The On Stage KSP100 Sustain Pedal is the direct pick for adding piano-style sustain control to an electronic keyboard. The Yamaha SK AW Workstation Kit is the more targeted choice for a Yamaha arranger workstation. Violin players looking at a full-size setup should focus on the 4/4 Violin Accessories Kit, which includes ebony fittings and alloy fine tuners in its description. For multi-channel audio routing, the STX807 Audio Cable is described as an eight-channel snake.
The deciding factor is specialization. Choose the accessory that matches the task already in front of you rather than trying to compare all four as interchangeable gear.

Product notes
Yamaha SK AW Workstation Kit
The Yamaha SK AW Workstation Kit makes sense for the focused case of a Yamaha arranger workstation. It is identified for electronic keyboard use and carries Yamaha compatibility, so the fit is clearly centered on that instrument family. Choose it when your priority is an accessory kit tied to an arranger-workstation setup rather than a general-purpose pedal or cable. Its limitation is the same specificity that makes it useful: the stated compatibility is Yamaha, not Universal. At USD 35.20, it sits above the pedal and violin kit while remaining well below the audio cable.
On Stage KSP100 Sustain Pedal
The On Stage KSP100 Sustain Pedal is the clearest match for an electronic keyboard player who specifically needs piano-style sustain control. Its Universal compatibility designation gives it a broader stated instrument match than the Yamaha-focused kit, while the black pedal is also described as non-slip and durable. That makes it a practical choice when the desired addition is a single keyboard-control accessory. Its boundary is its purpose: the KSP100 is a sustain pedal, not a violin component set, workstation-focused kit, or multi-channel audio-routing solution. Its listed price is USD 29.95.
4/4 Violin Accessories Kit
The 4/4 Violin Accessories Kit is the relevant choice when the need is centered on a full-size violin rather than an electronic keyboard or audio connection. The description calls out undyed ebony fittings and sturdy alloy fine tuners, and the attributes identify the set as handmade and lightweight. Those details give the kit a component-oriented role for violin work. The important limitation is the size designation: it is specifically identified for 4/4 violin. At USD 25.22, it is the lowest-priced option in this comparison, but its appeal is its violin-specific focus rather than broad crossover use.
STX807 Audio Cable
The STX807 Audio Cable is for a different kind of setup: moving multiple audio connections rather than adding keyboard expression or violin fittings. It is described as an eight-channel snake, and its cable type is XLR, making it the natural selection for a multi-channel audio-routing task. The stated seven-meter length gives it a defined run length to plan around. That fixed cable role is also its limitation, since it does not address the control or instrument-component needs covered by the other three accessories. At USD 114.73, it is the highest-listed item here.
Final recommendation by use case
For keyboard sustain, pick the On Stage KSP100 Sustain Pedal. For a Yamaha arranger-workstation setup, pick the Yamaha SK AW Workstation Kit. For full-size violin components, pick the 4/4 Violin Accessories Kit. For multi-channel audio routing, pick the STX807 Audio Cable. The right match comes from the job each accessory is built to address.
