I am the original owner of this Skylar reverb pedal.

It has been well cared for, no velcro was added and it was used with its own power supply.

From GFI:

Skylar packs four quintessential GFI System reverb algorithms into a compact pedal that is straightforward and easy to use. Intuitive user interface coupled with an LCD screen make it a breeze to navigate through Skylar’s vast sonic palette and features.
 
Input/Output
Skylar supports both mono and stereo input/output. Mono connection is made using standard TS patch cables while stereo connection is made via TRS patch cables (a splitter-Y cable may be needed).
 
External control
A multi-purpose jack provides connection to an expression pedal or tap-tempo pedal. Expression pedal input enables expressive control of reverb parameters, and the external tap-tempo can be used to control the tremolo speed in the Tremble algorithm.

Algorithms:

• Spatium
• Shimmer
• Plate
• Tremble (tremolo-reverb with tap-tempo)

Key Features:

• 4 select reverb algorithms.
• 2 presets
• 4 knobs with button
• Intuitive interface with LCD screen.
• Mono / Stereo input and output.
• Expression pedal and tap-tempo input.
• Momentary action supported.

Specifications:

• Input impedance    : 1 MOhm.
