The JET-1 is a compressor pedal from Dedalo FX, an analog design RockBoard's PedalPedia describes as "a compressor with FET technology and studio-grade opamp"1. Compression evens out the difference between your quietest and loudest notes, and a FET-based design takes its cue from the fast-acting field-effect transistor circuits used in studio gear.
What it does
As a compressor, the JET-1 sits in your signal chain to smooth out dynamics: quieter notes come up, louder ones are held back, and sustained notes hang on longer. Dedalo FX points to two things that shape its character. The first is the FET technology paired with a studio-grade opamp, which the maker presents as the core of the design. The second is the NUKE mode, which RockBoard's PedalPedia says "extends the action beyond correction into the squashed grounds of overcompression"1.
That distinction matters in practice. With NUKE off, the pedal works in the corrective range most players use compression for: evening out picking dynamics and keeping levels consistent. With NUKE engaged, the pedal moves into heavier squash, the kind of compressed sustain that sits well under lead lines. Because the circuit is analog, the effect happens without digital conversion in the path1.
Power and practicalities
The JET-1 runs on 9V DC with a center negative polarity and draws 12mA1. That is a light draw by pedal standards, so a standard pedalboard power supply output handles it without trouble.

Questions
What kind of effect is the Dedalo FX JET-1?
It is a compressor pedal. Dedalo FX describes it as a compressor with FET technology and a studio-grade opamp, and it runs on an entirely analog circuit. A NUKE mode extends its action beyond gentle correction into the squashed territory of overcompression, so it can work as both a subtle leveler and a heavier squash.
How is the JET-1 powered?
It runs on 9V DC with a center negative polarity and draws 12mA. That low draw means it sits comfortably on a pedalboard power supply alongside other pedals, and the analog circuit means there is no digital conversion in the signal path.
