The PaintAudio Foot Captain SWL is a compact expression control pedal with one extra trick most expression pedals do not have: a latched switch output that lets you turn an effects module on and off with a heavy stomp, while the rocker handles the expression duty. PaintAudio describes it as "a compact and lightweight expression control pedal that maintains a proper foot feel."1
What it does
An expression pedal does not make a sound of its own. It sends a control signal to a host device, sweeping a parameter such as volume, delay time or a wah-style filter as you rock the pedal. The Foot Captain SWL's main feature, per PaintAudio, is "the combination of two output modes: Tip output and Ring output."1
That matters because expression pedals have long been split into two wiring standards. Even though both Tip and Ring outputs use the same TRS connector, PaintAudio notes there have always been two different conventions, and pedals wired one way may not talk to devices expecting the other. PaintAudio's own MIDI Captain Blue controller, for example, is described as "only compatible with expression pedals that have Ring output," with Tip-output pedals such as the Fractal EV1, Boss EXP and Hotone EXP flagged as possible compatibility problems.2 The SWL covers both standards from one pedal, and PaintAudio says its 25k impedance design "can perfectly adapt to almost all host devices available on the market."1
The latched switch output
The "SWL" in the name refers to the switch. PaintAudio describes it as a way to "control the effects module by a heavy stomp," with the host device needing switch input capability.1 In practice that means the pedal can do two jobs at once: sweep a parameter with the rocker and toggle an effect block on or off with a firm press, on devices that accept a switch input alongside their expression input.
Connections and cable
The SWL connects with a 6.35mm TRS (Tip-Ring-Sleeve) three-core cable, and one is included in the package. PaintAudio is explicit about the cable type: "Please do not use regular guitar signal cables."1 A standard guitar cable only carries the two connections a mono signal needs, while an expression pedal needs all three conductors of a TRS cable to work.
Use only a TRS three-core cable with the Foot Captain SWL. A regular guitar signal cable will not carry the expression signal correctly, and PaintAudio advises against using one.1
Foot Captain SWL compared with the Foot Captain
PaintAudio's Foot Captain is the SWL's sibling: "a cost-effective expression pedal that is fully compatible with standard output formats," with two expression interface outputs covering Tip and Ring standards, making it compatible with almost all multi-effect processors that support an expression pedal input.3 The Foot Captain Expression Pedal page on RockBoard's PedalPedia likewise says you can use it "to control almost all effects devices, keyboard devices, and MIDI controllers available on the market."4
| Foot Captain SWL | Foot Captain | |
|---|---|---|
| Expression outputs | Tip and Ring via TRS, dual-standard1 | Two expression interface outputs5 |
| Latched switch output | Yes, heavy stomp, host needs switch input1 | Not listed |
| Weight | 0.4 kg1 | 430g5 |
| Enclosure | Aluminum alloy1 | Aluminum alloy5 |
| Status | Listed by PaintAudio5 | Sold out5 |
The two are close in weight, with the SWL at 0.4 kg and the standard Foot Captain at 430g, and both use aluminum alloy enclosures that PaintAudio describes as very sturdy.15 The practical difference is the switch: if your host device has a switch input, the SWL adds stomp control the standard Foot Captain does not list.

Questions
What does the latched switch on the Foot Captain SWL do?
The latched switch output lets you control an effects module by a heavy stomp, toggling it on or off in the way a latching footswitch does. PaintAudio notes that the host device needs switch input capability for this to work, so it is worth confirming that your multi-effects unit or MIDI controller accepts a switch before relying on it.
Can I use a regular guitar cable with the Foot Captain SWL?
No. PaintAudio states the pedal uses a 6.35mm TRS (Tip-Ring-Sleeve) three-core cable, one of which is included in the package, and asks users not to use regular guitar signal cables. A standard guitar cable does not carry the three connections an expression pedal needs.
What is the difference between the Foot Captain and the Foot Captain SWL?
Both are compact, lightweight expression pedals in aluminum alloy enclosures from PaintAudio. The SWL adds a latched switch output that controls an effects module by a heavy stomp, on top of the expression outputs. The standard Foot Captain provides two expression interface outputs and was listed as sold out on PaintAudio's page.
Does my device need a switch input to use the SWL switch?
Yes. PaintAudio describes the latched switch output as controlling the effects module by a heavy stomp, and notes that the host device needs switch input capability. The expression outputs are separate and work with host devices that accept an expression pedal input.
How heavy is the Foot Captain SWL?
PaintAudio lists the Foot Captain SWL at 0.4 kg, which the company describes as just right for a pedal of this kind. The standard Foot Captain is listed at 430g, so the two are very close in weight.
