It sounds too thin to me, well not thin but it lacks that certain fluid cream, I think I'm missing the big balls power section sound. Could you post a clip with the amp cranked?

u are correct! the PPIMV takes away from that. ill post a clip of it using some power.

i pulled mine and put a PTP in in it. don't know much about the green caps it had on the PCB mainly so i could tweak.

Your amp sounds great. I like the Darburst better over the JB. The Darkburst sound like it has less gain with better definition . The JB sound like it has more gain and sounds kind of muddy.

I have a G&L Legacy with a JB in the bridge in a HSS configuration. I think the JB in my guitar sounds kind of muddy. Thinking about changeing it for something else that is why I asked you about your reasons and opinions on changeing your pickups. Building a 50watt Plexi and looking for advice on what to change the JB out for.
