The Old Blood Noise Endeavors Expression Slider is a small, entirely passive fader for controlling a parameter on any pedal with an Old Blood style expression input. Instead of rocking a expression pedal back and forth with your foot, you move a 50K slider with your hand, which Old Blood Noise Endeavors positions for external control "where you need it - on the desk of your studio, velcroed to a guitar strap, or wherever else" suits the player.1
What it does and how it works
The Slider is a hand-operated fader rather than a foot pedal. Its jack wiring puts the tip on the wiper of a 50K slider, the standard arrangement for expression control, so moving the fader sweeps whatever parameter the connected pedal assigns to its expression input: a delay's blend, a filter's cutoff, a reverb's mix, whatever the host pedal offers.1
Because it is entirely passive, it needs no power supply, no battery and no current draw from a power supply, and it adds nothing to the signal path beyond the control voltage the host pedal reads.1
Compatibility
Old Blood Noise Endeavors states that the Slider works with any pedal carrying an Old Blood style expression input, and that it has confirmed compatibility with1:
- All Old Blood Noise Endeavors pedals
- Chase Bliss
- Meris
- EarthQuaker Devices
- Empress
- Montreal Assembly
- Red Panda
- Strymon
- Electro-Harmonix (EHX)
- "and more"1
That list covers a wide slice of the pedal market, including makers known for deep expression control over delay, reverb, filter and modulation parameters.1
Size, price and versions
At 2" wide by 3.75" high by 2" deep, the Slider is compact enough to live off the pedalboard entirely, which is the point of its design: it goes where the control is handiest rather than under your foot.1 It lists for $44.00 USD.1
The Slider comes in three colorways: Basic, HK and Setback. The art on the HK version is by Holey Kids, whose artwork Old Blood Noise Endeavors has also applied to other utility pedals in its range.1
Where it sits in the OBNE expression range
The Slider is the simplest of Old Blood Noise Endeavors' expression controllers. The Expression Ramper stores two expression presets and moves between them automatically, and the Expression Ramper X3 handles three expression outputs with sync options. For players who want to automate parameter movement rather than move a fader by hand, those pedals cover it; for direct, manual control of a single parameter, the Slider is the stripped-down option.1
The Expression Slider is entirely passive, so it only works on pedals with a compatible expression input. It is not a volume pedal or a standalone effect on its own.

Questions
Does the Old Blood Noise Endeavors Expression Slider need power?
No. Old Blood Noise Endeavors describes the Expression Slider as entirely passive, so it requires no power supply at all. There is no battery or adapter to worry about, and it draws nothing from your pedalboard's power supply. You simply connect it to the expression input of a compatible pedal and move the slider to change that pedal's parameter.
Which pedals work with the OBNE Expression Slider?
Old Blood Noise Endeavors says the Slider works with any pedal that has an Old Blood style expression input. The maker confirms it works with all Old Blood pedals as well as pedals from Chase Bliss, Meris, EarthQuaker Devices, Empress, Montreal Assembly, Red Panda, Strymon and Electro-Harmonix, among others.
What is the HK version of the OBNE Expression Slider?
HK is one of three colorways of the Expression Slider, alongside Basic and Setback. The artwork on the HK version is by Holey Kids, an artist whose work Old Blood Noise Endeavors has also rolled out across other utility pedals in its range.
How big is the OBNE Expression Slider?
Old Blood Noise Endeavors lists the Expression Slider's dimensions as 2 inches wide, 3.75 inches high and 2 inches deep. That is small enough to sit on a desk in the studio, attach to a guitar strap, or otherwise place wherever you want hands-on control of a pedal parameter.
