I run a 5-String Fender w/Active Nordstrand Electronics and Pups through an Eden rig.. The sound I get is very articulate. Every note is heard and well defined.. What I want to be able to achieve is an old school "fat" type of sound. Merely rolling off the tone knob or using the EQ doesn't quite do it.. Would a compressor be the trick? I've been doing some research and it looks like a tube type compressor, such as the Markbass Compressore, would probably be the best bet. Any suggestions?
