I have recently installed a Duncan Custom SH5 in the bridge of my Santana se and I love the sound of it when I use it to practice with at home, nice and full and chunky with edge. But when I use it on stage Im finding it too be slightly to trebly/harsh and the mic im using seems to pickup all the grainyness and hi end and send it through the PA, Is it my amp or is the pickup just voiced this way. I am using a Vox Pathfinder 15R miked up thru a PA and have the treble around 4 and the bass around 7. I have tried placing the mike in different places. Im getting real anoyed cause ive tried a couple of duncans and I always ending up questioning the high end. Should they be used with 250k pots?
