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.

Comments about Markbass Compressore Tube Bass Compressor Pedal:

I first was a bit intimidated by this pedal because of all the controls on it. I settled for a different compressor with only 3 knobs & wasn't completely happy with it. This Markbass compressor is what I was looking (& listening) for! It just took me a while to realize it. Anyways, all the controls on this pedal help really dial in your sound. I like the ratio, threshold, & release knobs. There are YouTube videos & message forums out there that helped me understand what each control does. Take a little time to learn what this thing does, & I'm sure you'll be happy with it. The price is up there, but the quality is solid & I'm confident this pedal will last me a long time. This compressor runs on 12v with its supplied power supply. This isn't a big deal for me at all. This is normally the only pedal I use at church. It's an "always on" pedal for me. When I click this pedal off at my church, it pops in the speakers. This pop does NOT happen with my amp at home. I feel this is something going on with my church's sound system. Just wanted to let y'all know that might happen with some sound systems. Even with the pedal disengaged, the tube is on when you've got the pedal plugged in. You can barely see an orange glow in the tube. The blue "on" LED is super bright! It would annoy me if I had to look at it for more than just a little bit. I don't normally spend time staring at my pedals so not a huge deal. The yellow LED lets you know the intensity of compression going on. This is very helpful to me in setting the controls. The yellow LED is not super bright like the blue one. Overall, if you can handle the price, the bigger size of the pedal, & that it has to have its own power supply, then I highly recommend giving this compressor some consideration. I consistently get compliments on my sound. I've used this pedal with my custom G&L SB-2 & Epiphone Les Paul bass.

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.
