The Darkglass Anagram Press is a compact expression pedal designed for bass players who value reliability, simplicity, and precise control, according to the maker's product page1. An expression pedal does not make sound of its own: it sends a control signal to an expression-enabled device, letting you sweep a parameter such as delay time, filter frequency or volume with your foot. Darkglass describes the Anagram Press as delivering a smooth, linear response for controlling expression-enabled devices1. It sits alongside the Darkglass Anagram Expression Pedal in the maker's range, and belongs to the wider family of expression pedals.
Darkglass's product page listed the Anagram Press as sold out as of 25 October 20261.
Controls and connection
The pedal's output is a 1/4 inch (6.35 mm) TRS connector with a linear taper1. In plain terms, the pot is the internal track the pedal's rocker sweeps, and a linear taper means the movement maps evenly to whatever parameter you are controlling, with no bunching at either end of the travel. That is what Darkglass is referring to when it says the pedal delivers a smooth, linear response1.
The LED array displays the pedal position1, so you can see where the rocker sits at a glance, which is unusual on a simple expression pedal and useful on a dark stage.
Power
The Anagram Press can run on a 9V battery, but the battery operation is optional1. The expression function itself works without power; the battery serves the LED position display. There is no external power specification listed on the maker's page.

Questions
Does the Darkglass Anagram Press need a battery?
No. The 9V battery operation is optional, according to Darkglass's product page. The pedal's core function, sending expression data over a TRS connection, does not require power, so the battery is there to light the LED array that displays the pedal position rather than to make the pedal work.
What kind of cable does the Anagram Press use?
The Anagram Press connects with a 1/4 inch (6.35 mm) TRS connector with a linear taper, which is the standard arrangement for expression inputs on pedals and effects units. A standard stereo TRS cable is what carries the connection.
How much does the Anagram Press weigh?
Darkglass lists the weight at 0.95 lb, with dimensions of 6.38 x 3.19 x 2.01 inches (width by depth by height). That makes it a compact pedal that is easy to carry in a gig bag alongside the rest of a board's gear.
