I have a Warwick Fortress One, and I feel like the MEC preamp isn't good, and that I should replace it. When I have the treble and bass controls set flat, the sound I get is really bright, and almost brittle sounding. To get the sound I want, I have to back the treble up all the way. I want a preamp that sounds good flat, and that has a passive switch. I was thinking that maybe the boost only Sadowsky or Aguilar would be more natural sounding, but I don't want to risk being stuck with a sound that's too bright, and not being able to cut the treble. I was wondering if anyone could suggest one of the mentioned preamps, or something different.
