For description, see the website EMG. I installed two days ago this kit on a Vigier Excalibur Supra with his own bland but I dcevait. Then, it's a vamp! The sound is poustouflant! A true sound of strata, round and generous, I would say "organic" but with a certain modernity net, precise, dynamic. My VIGIER, which I love the comfort, life and sky is clear now takes a true modern strat personals. Amp plugged directly into a lamp is beautiful in its clear and crunchy, distorted with incredible sustain. Beware, the bridge pickup used only lack of level (as all strata elsewhere), it is impracticable to exploit the height of the 3 microphones to adjust levels. I COMPLT the kit with a switch that allows you to force engagement of the neck pickup which can have 2 sounds very interesting supplmentaires: neck pickup and bridge pickup + neck + middle + bridge. I use the EXG Knob halfway constantly Knob SPC and as a booster for the solo part to get out of the mix. In conclusion, since i was 20years tank on active EMG pickups, here I am conquered.
