"The Alesis Andromeda is legendary. The first (and unfortunately, last) analog synth from Alesis sounds incredible and has a deep and extensive voice architecture. This unit has been serviced, all pots, wheels, aftertouch, and ribbon pass the diagnostics. A new blue display has been installed. There are some scratches and wear marks on the case, but nothing egregious."

Pics of the inside below.
"From my testing I gathered the following: the two pole switch turns the filter control on (down position) or off (up position). When the filter control is on, the pedal acts like intensity or swell, and the speed is controlled by the knob. When the pole switch is off, the signal passes through with the option to either bypass for a clean signal or act as a swell pedal depending on whether the pushbutton switch is pressed (located at maximum pedal depression). This is the limit of what I could test. Please keep in mind, the pedal is sold as is.
SN 0073
I have installed two new 9V batteries, which have only been used for testing the pedal during the demo video filmed on 12/07/25. The unit has remained off since testing."

Introducing ADDAC System Toe Twisters
video upload by ADDAC System
"At ADDAC we’re always interested in simple effective solutions for sonic expression, as a by product of a new product development we came up with a simple solution for pedal users.
A special large knob that can replace any pedal knob and allows easy feet control.
This knob is tall enough so that it towers above the remaining pedal knobs, fitting in very tight spaces. At the same time creates enough clearance so that it’s accessible without obstruction and easier to find with your toe.
The side grooves create friction against the shoe.
Sold in packs of 4 Toe Twisters.
