Mooer Yellow Comp Compressor Pedal

Mooer’s Yellow Comp is a great option for anyone looking for subtle compression to smooth out their playing or fatten up their tone.

It’s also regarded to be very transparent, which is a huge plus for anyone who doesn’t want their existing tone to be colored.

Even better, this pedal is also true bypass so you won’t have to worry about it impacting your tone while it’s not engaged.


  • Optical compression
  • Parameters: Volume, Compression, and EQ (sweeps from heavy bass to accentuated treble)
  • True Bypass
  • 9-volt adapter ONLY (no battery compartment)


The only real flaw of this pedal is that it can’t be powered via a 9-volt battery, you have to use an adapter. This isn’t a huge deal if you already have a multi-pedal power supply, but if you run all of your pedals off of batteries the Yellow Comp’s lack of a battery compartment will likely be a deal breaker. The Yellow Comp’s onboard controls are limited, with the device only featuring a volume, compression, and EQ parameter knobs. The lack of either an attack or release knob limits the unit’s usefulness in some genres, such as more technical styles of metal or hard rock and country.


However, unless you happen to play one of the aforementioned genres the Yellow Comp will likely still have a positive impact on your rig. Another thing that shouldn’t be ignored is that this unit is also pretty affordable and doesn’t have a huge footprint, so it’s definitely worth a look if you already have a bunch of pedals on your board.


This is one of the better mini compressor pedals available, however we are currently recommending the more highly rated Xotic SP.
