Markbass Tube Compressor

A pedal with a "studio compressor" spirit, designed for pedalboard format

The COMPRESSORE was conceived to bring, in a pedal, the type of control expected from a studio compressor: threshold adjustment, ratio, and timing controls (Attack/Release), rather than a simple "sustain" knob. Its built-in tube provides a smoother response and a sense of depth, particularly appreciated when taming playing dynamics without flattening the sound.

Thanks to its connectivity including a balanced XLR output and Ground Lift, it can also be used as a true "plug-and-play" dynamic tool in live settings, while remaining easy to integrate into a classic effects chain.

Who is the COMPRESSORE for, and in which styles does it make a difference?

This pedal is aimed at bassists (and guitarists) seeking precise compression : from intermediate musicians looking for a more consistent sound in a band, to professionals wanting fine control on stage and in the studio. It excels in styles where dynamics are central: funk, pop, rock, reggae, soul, gospel, but also for more modern and controlled sounds when you want to "lock" the low end.

In live contexts, it helps stabilize levels without fighting the mix, and its balanced XLR output is a real advantage for going straight to the console. In the studio, it smooths attacks, extends sustain, or simply makes playing more even, especially on fingerstyle/slap passages or very pronounced pick attacks.
