I consistently am unable to get the same high end clarity in my sound when I negage my filters. I will say that even though I have been playing for 30 years, I am a relative effects novice (newby). I have tried the MXR Bass Envelope FIlter and now have the EBS. I have to set the EBS with all the knobs wide open and then crank up the highs on my Roscoe basses. The one I use mainly has an Aguilar OBP 1 pre and has an insane amount of high and and with this one I get a great sound but only after I boost the highs from flat to about 50%. Am I doing something wrong that my filters sound so muddy? Am I giving them too much of a hot signal comming out if the bass? I really doo not understand how the effect works as far as what it does what the signal and I also do not know if this is just how filters sound? Any info would be greatly appreciated.
