I am having some trouble with my new EBS Milticomp compressor. I am using it with an active bass guitar. I either use a Ampeg 3Pro or Ampeg CL head with a 410 cab. The unit has 3settings Normal, Multiband & Tubism. I can switch back & forth to these settings and the sound doesn't change. The sound doesn't change when I move the Comp/Limit & Gain buttons either. Also, when I press the foot switch (bypass) and the red light is on ... is the unit on or off. There also adjustments that can be made inside the unit to adjust the high & low threshold. (as instructed in the manual) What will this do for the sound. The compression ratio is a max of 5:1 How will adjusting these things affect the compression. I have head so many good things about this unit, buy so far it has been a major disappointment. Are there any tips that someone might pass on to me based on their experience with this unit. Thank you.

I've been using a DBX 1066 that I borrowed from a friend, but had to return it. I like to use lots of compression because I play heavy. Any suggestions regarding the trim pots if I am a heavy player (with uneven strikes at times)? Thanks again.
