The MOSKY Spring Reverb Mini, model MP-51, is a compact spring reverb pedal from Chinese maker Mosky. Mosky pitches it as "all the great sound of a reverb tank in a small little pedal," built into what the maker calls a super small size1. Press coverage describes it as an affordable emulation of the Malekko Omicron Spring, a pedal Delicious Audio credits as "the first pedal to offer spring reverb in a mini enclosure"2.
What it does
Spring reverb recreates the sound of the mechanical spring tanks found in vintage guitar amps, where the signal is sent through springs that add a shimmering, sometimes boingy tail to your tone. The MP-51 puts that effect in a mini enclosure, aimed at players who want reverb on a small pedalboard1.
The pedal has one control:
| Control | What it does |
|---|---|
| MIX | Adjusts the dry/wet balance between your clean signal and the reverb1 |
Because the only knob is a mix control, the character of the reverb itself is fixed: you set how much of the effect blends with your dry signal, and the pedal handles the rest1.
Where it came from and how it compares
Delicious Audio's Paolo De Gregorio described the pedal as "a super affordable, but rather popular, Chinese emulation of the Malekko Omicron Spring"3. The Omicron Spring, made by Malekko, was noted by the same publication as the first pedal to put spring reverb in a mini enclosure2, which makes it the circuit the MP-51 follows.
"A super affordable, but rather popular, Chinese emulation of the Malekko Omicron Spring."
If you are comparing mini spring reverbs, several other small options are worth knowing:
The MP-51 stands apart from Mosky's own Multi Spring Reverb by keeping things to a single mix control rather than offering multiple reverb modulation modes14.
