The Mosky Dynamic Compressor is a mini compressor pedal from Mosky, listed by the maker as a "Dyna Compressor" and, more specifically, as based on the MXR Dyna Comp circuit. It is a compressor pedal in the classic mold: Mosky describes it as creating "infinitely clean sustain" with a signal-limiting processor that varies its gain so the output signal stays constant, leveling out the difference between quiet and loud playing1.
What it does to your sound
A compressor evens out a player's dynamics: quiet notes get pushed up and loud notes pulled down, so everything arrives at the amp at a more consistent level. Mosky describes the Dynamic Compressor as designed to level the output signal of your playing and stabilize the dynamics of the output, which is what produces the clean sustain the maker claims1. In practice, that is the same job the Dyna Comp circuit has done since MXR introduced it, and it is why players reach for this kind of pedal for country chicken-pickin', clean funk rhythm, and tightening up single-note lines.
Controls
The pedal keeps the Dyna Comp's famously simple two-knob layout1:
| Control | What it does |
|---|---|
| Level | Sets the output level of the pedal |
| Sensitivity | Sets how hard the compressor reacts to your playing |
Mosky's page also notes that the COMP ensures smooth playing, which is the pedal's way of saying the compression itself is fixed in character and the knobs set how much of it you hear and how hard it clamps down1.
Power, size and bypass
The Dynamic Compressor runs on a 9V DC supply with negative tip polarity, the standard center-negative format used by most pedalboard supplies1. Mosky does not list a current draw figure or a battery option for the pedal. The enclosure is genuinely mini: dimensions of 94(L) x 39(W) x 32(H) mm, weighing 125 g, so it takes up little room on a board1. Switching is true bypass, meaning the circuit is fully out of the signal path when the pedal is off1.
Mosky specifies 9V DC negative-tip power only. As with most mini pedals, there is no mention of battery power, so plan on a standard 9V DC center-negative supply.
Where it came from and how it compares
Mosky states plainly that the pedal is based on the MXR Dyna Comp1. That places it in the same family as Dunlop's compressor, and it explains the pedal's stated approach: Mosky describes it as creating "infinitely clean sustain" through "a signal-limiting processor that varies its gain so that the output signal stays constant"1. In other words, like the circuit it is based on, it levels the output signal and stabilizes dynamics rather than shaping tone directly1.
The Mosky sits in that same mini-pedal territory at a lower price point, and it is not the only budget take on the format: Harley Benton's Dynamic Compressor is another mini Dyna Comp-style pedal, also with true bypass switching2. Within Mosky's own range there are related options, including the Mosky Dyna Compressor, the MOSKY Compressor, the Mosky Roller Compressor, the Mosky MINI C4 COMPRESSOR and the Mosky SUPER OPTO, each a different take on compression from the same maker.

Questions
What pedal is the Mosky Dynamic Compressor based on?
Mosky states on its product page that the Dynamic Compressor is based on the MXR Dyna Comp, the classic signal-limiting compressor circuit. The pedal follows the same two-knob format, with controls for output level and sensitivity, and Mosky describes it as creating clean sustain by using a signal-limiting processor that varies its gain so the output signal stays constant.
Is the Mosky Dynamic Compressor true bypass?
Yes. Mosky lists the Dynamic Compressor with a true bypass switch, so when the pedal is off, the input jack connects straight to the output jack and the circuit is removed from your signal path entirely.
What power supply does the Mosky Dynamic Compressor need?
The Mosky Dynamic Compressor runs on a 9V DC supply with negative tip polarity, the same center-negative standard used by most modern pedals. Mosky does not list a current draw figure or battery option for the pedal, so a standard 9V DC center-negative supply is what to plan for.
Is the Mosky Dynamic Compressor analog?
Yes. Mosky describes the Dynamic Compressor as having a 100% analog signal path, meaning your guitar signal is compressed by analog circuitry rather than converted to digital and back again.
