Quite a bit of control actually. The volume knob is self explanatory, as is tone. Sustain lets you dial in how long you want your notes to ring. Compression dials in the extent to which you are squashing the signal volume, boosting lows, and bringing down anything loud.

The Battery change feature actually really nice, a lot of pedals require unscrewing the bottom of the pedal, this is quite a bit simpler.

Generally, I've found the buffer to be very low quality, and really does a horrible job of preserving your bypass tone.


To be honest, this is one of the very worst compressors that I have had the pleasure using. In a nutshell, it turns your guitar into a rubber band. Some compressors will do a pretty good job of retaining some dynamics. This one pretty much steamrolls your playing, you get one one volume, that is it. The higher up the compression and sustain settings, the more noise you get. And forget about using it with anything high gain, that will take you right into the land of feedback.

Very little that I like about the sound of this pedal at all. I found it to be pretty much unusable.


Save your money. Compression isn't really an effect that you ever want to cheap out on. It can destroy your tone far too easily. At this price point, look into the MXR dynacomp. For a little more, the Barber Tone Press is killer. And for a little more than that, the Diamond Compressor is hands down the best I've used, topping an $800 BJFE compressor in my opinion.

There really isn't any budget or setup that I would recommend this under.
