    5.0 out of 5 stars Works Excellent On My 5-String Bass
    Reviewed in the United States on November 2, 2022
    Style: GuitarVerified Purchase
    I'm a bass player with a 5-string bass. I was looking for more sustain, not the compression so much. First I bought the Behringer CS400 Compressor/Sustainer pedal to try to save some money. It cost about $21. After a few days of playing through the pedal, I noticed high levels of audible distortion. It was as if this thing was a distortion pedal. I thought it was a dying battery so I tried a new one, then an external power supply, but it was no use. The distortion was so loud that I simply could not use the pedal at all if I wanted a clean sound. I don't recall distortion being there when I first started using this pedal, but it was there now, loud and clear. The pedal had become completely useless to me.

    I then reluctantly forked over a Benjamin Franklin for this Boss CS-3 pedal. As soon as I plucked the first note, there was sweet sustain with no audible distortion to my ears. I've been playing through it for several days now and it is still as clean as it was on day 1. Now I have a true compressor/sustain pedal. I should have just bought this in the first place instead of wasting $21 on a cheaper knock-off.

    The moral of the story: Buy the Boss pedal first, don't waste your money on cheaper models.

    Pour les pickups actif ou passif, aucun problème pour moi à ce niveau, juste besoin d'ajustement selon ce que tu utilise, ces normale !

    Played a riff with very loud chords and a much quieter lead line. Turning the pedal on the volume of the chords was significantly reduced without any loss of oomf. Like it didn't lose any of its feeling, it was just quieter, allowing me to turn up the over all volume to significantly increase the volume of the lead line. I've used a few cheaper compressors before but this one really impressed me!! Great pedal!!
