Compact TRS, Compact TS, Micro TRS, Micro TS
Saturnworks compact and micro expression pedals provide expression capability for a variety of devices from manufacturers such as EHX, Moog, Boss, Strymon, Line 6 and Eventide. An included Dunlop rubber knob cover makes the compact expression easy to adjust on the fly.
Expression pedals fall into two broad categories: devices that use the more common TRS (stereo) connections and less common TS (mono) connections. EHX, Boss, Strymon, and Moog use TRS, while Line 6 and Eventide use TS. Please consult with your device’s owner’s manual or contact us to help determine which type of expression your device requires.
Micro and compact expressions come with either a 10K or 100K pot with a TRS jack with the tip set as the wiper.* Theses pot values are the most common TRS expression configurations. The 10K is the same configuration as the well-known Roland EV-5 expression pedal. This setup will work with most TRS compatible devices. We can also install other pot values upon request. So if you would like a different pot, simply add a note to your order requesting the pot you would like as you go through the checkout process. If you have any questions regarding the compatibility of your device, please contact us.
TRS expression pedals must be connected with a ¼” TRS (stereo) patch cable to work properly. We have TRS cables available here.
TS expression pedals can be set up to use a 10k linear pot (Line 6) or a 25k linear pot (Eventide). When purchasing a TS expression pedal, please let us know in the ‘notes’ field as you check out which device you plan on using the pedal with, so that we can be sure it is configured correctly.
Double expression pedals combine two separate expression pedals into one enclosures. They are available in TRS/TRS, TRS/TS, and TS/TS variants.
It’s difficult to list every possible pot/jack combination on our site. If you’re looking for a particular configuration, please include your request in the notes section of your order as you check out.
Switchable expression pedals switch between two different expression settings, which you can set with a pair of knobs. They are available in both latching and momentary versions. Our expression switches should work with devices that use standard TRS tip-wiper expression setups.*
Please note: We have found that our expression switches typically don’t work well with Line 6 or other devices that use TS expression configurations.
Micro Min/Max Expression Switches
The micro expression switch simulates the max heel-down and max toe-down positions of a full size expression pedal, but in a micro package. They are available in both TRS 100k and 10k configurations. Check out a demo of the micro expression pedal here. We have found that our micro min/max expression switches typically don’t work well with Line 6 or other devices that use TS expression configurations.
Full Size TRS
The Saturnworks full size expression pedal is build like a tank. Housed in a solid cast-aluminum wah case, it is ready for heavy-duty use.
The Saturnworks expression pedal features a durable Neutrik jack and a wah pot with a dust cover.
Please note: the configurations currently available are a TRS setup with a 100k pot, a TRS with a 10k pot, or a TS with a 10k pot. The TRS configurations will work with Strymon, Boss, EHX, and many other devices that spec a TRS expression, which is the most common configuration. The 10k TS setup works with Line 6 devices.
Full-sized expression pedals are custom made-to-order. The turnaround time is approximately two weeks.
Please note: The wah enclosures we use for these expression pedals can sometimes be hard to come by and we don’t often have many color/finish options. We usually have either plain brushed aluminum or textured black. We will build/send what we have available; however, we can’t always guarantee that a specific finish is available.
Expression Control Switch
The expression control switch allows you to use a single expression pedal to control up to three different devices. Connect your expression pedal and your devices into the switch and use the toggles or footswitches (depending on the version) to select which device you would like to have access to the expression pedal. The pedal works with standard TRS expression setups. You must ensure that any device you connect is compatible with your expression pedal.
Please note: The controller is designed to only have one device active at a time.
Please also note: Regarding using the expression control switch to control multiple devices, some devices enter ‘expression mode’ when a cable is connected to their expression jacks, regardless of whether or not an expression pedal is connected or active. These devices may perform unwanted functions, even if an expression pedal is not connected. In those cases, connecting an expression pedal to two devices with an expression control switch may not produce satisfactory results. You can test how your device will behave with an expression connected but not turned on by simply plugging a patch cable into its expression jack with nothing on the other end. Whatever the device does in that scenario, will be what it does with the control switch channel connected but turned off.
Tip wiper vs ring wiper
*A note on tip wiper vs ring wiper. The majority of expression pedals and devices that use TRS-configured expression pedals use a tip wiper setup. This includes Boss, EHX, Dunlop, Moog, Strymon, MXR, and many more. We have seen a handful of devices that use a TRS ring wiper setup. This includes some devices from Caitlinbread. If you’re not sure, please consult with your device’s manual and/or manufacturer to confirm that it uses expression pedals with the standard TRS tip-wiper setup. If your device uses a ring wiper setup, please let us know in the order notes section as you check out.
