We don't know what the PROMAG PLUS is. Is this something new? It's not shown in our most recent Elderly Instruments catalog. We've been using Dean Markley Pro-Mag pickups in our guitars for over 20 years and have always found that they are quite sensitive. We have to keep the gain on the guitar chnnels lower than the vocal channels to get a proper balance.

When we used the single coil type, we sometimes had trouble picking up a horrible buzz coming from some other piece of equipment in the venue (not ours). Since we switched to the double coil, humbucking type, we have had no problems. We love these pickups because we often play with no PA and can just pop them in and out at will.
