Title: Plexi 50 lead (1987) EQ problem Post by: Am_I_Evil on May 07, 2011, 04:12:35 PM Hi,
I have problem with my plexi 50 Lead. Controls: presence, bass, middle, treble are not responsive enough. I can hardly hear the difference if i have treble,bass,... on max or min. Master volume (PPIMV), bright and normal controles works fine. Does anybody knows haw can I fix this? thanks uros Title: Re: Plexi 50 lead (1987) EQ problem Post by: cmoore on May 07, 2011, 06:06:41 PM Who built the amp.?

Keep in mind that the lower that you have the PPIMV the less negative feedback that you will allow the amp to have. As you go lower the first thing to stop working will be the presence. The amp will feel gainier and the other controls will begin to seem less responsive. If you're running the PPIMV low, then it's the nature of it. If you set it higher than halfway or so and still have the problem, then it could be something else like a broken connection of the mids pot to ground.

thank's for answer. I grounded all controls with wire, now works much beter. But i think it must be even more responsive, I know it will sound stupid, but i can't get to much treble or midle. All amps that I played has to much treble, midle... if you turn control to max. Except this one.
