Equalise,compress,stereo field,mutes... its a prctical device that works nicely at the end of your chain,to in a moment correct the equalisation,give it more presence or mute independently the highs/mids or low frequencys. Recomended if you work at high levels...

i dont need it at the end,so here you have it ,close to new, the knobs and buttons work perfectly without wobble...
