Hi, I have three seperate pieces which make up my "preamp" before my Mackie 1400 poweramp... 1. MXR M-80 Bass DI: This has EQ and has a tone shaping effect on the signal 2. RNC Compressor: is a really nice compressor (litrally!) 3. Seymour Duncan Pickup Booster: This is a clean gain stage I use to boost the level of the signal up to a nice volume for the poweramp. I am currently running them in the above order but would like some feedback if there is a better order to run them in???
