Hello bassplayers I'm new to this forum! I would really appreciate your I bought this unit brand new about 4 weeks ago. I spent a lot of time setting it up for a good bass compression, trying to make it work its best in my rig. I use to connect like this: YamahaTrb6II---> korgtuner ---> dbxIn1, dbxOut1--->dbxIn2, dbxout2---> Line6BPXT pro ---> amp. Ok, I use first dbx channel for compression and the second one for gating. But I can' t understand why playing low open strings like E (in particular) or B, the unit works in a strange way: threshold leds start flashing from green to red, then green to red again and so on, gain reduction leds start flashing between two db values and at the same time, the unit makes that strange sound, which is like ''frrrr'', during the attack! I found that playing E open string closer to the bridge makes the unit work as I described while playing it closer to the neck makes it work fine! But I can't play all the open E notes in a song on neck position just because it doesn't like ''low strings bridge vibrations''!! What do you think is the problem?
