Compressore is no mere stomp box—it's a state-of-the-art compression tool.

Markbass Compressore is a high-quality tube compressor pedal that features all the individual controls normally found on professional studio outboard compressors: gain, threshold, ratio, attack, release and volume. Not only designed for bass, this Markbass pedal can also be used with guitars or any acoustic or electric instruments, in either live or studio applications, thanks to its state-of-the-art component quality. The bass pedal's ECC 81 tube compresses your signal, evening out the sharp peaks of your playing in a natural, transparent way. At the same time, it also adds warmth and harmonics to your sound. Like all Markbass pedals, this one features "true bypass." So when the compressor is off, your signal goes directly from the input jack to the output jack without any degradation of audio quality.

While some compressor pedals offer individual control of nearly all compression parameters, the controls on most comp boxes adjust two simultaneously, and some only have a single "compression" knob. The Markbass Compressore features all the individual controls you would normally find on professional studio outboard compressors.

Better sound for my passive basses


from Undisclosed

Comments about Markbass Compressore Tube Bass Compressor Pedal:

When I first bought this pedal I was not very impressed. After using it for a few months, though, I am finding more uses, and more tones to my liking. I first thought that since I was using 100% markbass amplification and cabs, then I was not getting much incremental "goodness" to my tone by using the Compressore. But what I have come to find out, was that when I was playing active basses thru it, it wasn't giving me as much additional color as when I was playing passive basses thru it. And since I play both kinds regularly in my bands, this pedal has now earned a permanent spot on the pedal board.

If I can describe the tone improvement to my passive P and J basses, I guess it would have to be more fullness and roundness to the sound. I realize that its a more versatile pedal than just using it as a pre-amp, so if and when I do any recording, it will also come in handy to get that studio compressed tube sound.

Also, I was concerned about using the pedal on stage, because of the need to separately power the pedal (not compatible with the 9V infrastructure on my pedal board), but it turns out that the supplied power cord/wall wart is about as long as the cord of the power supply for my pedal board, so as long as I have two spots open on my power strip, I am OK with the separate power issue.

Overall rank a 9 out of 10.
