The TESLA PLASMA-3 pickup produces a very heavy and powerful tone, with clear highs and plenty of mid-bottom tones, ideal from heavy metal or rock. Plasma-3 pickups are carefully made with a polyurethane coated copper wire; Alnico 5 bar type magnets. The coils are wax potted for stabilization to insure the complete, clean reproduction of sound. Quiet when needed, the Plasma-3 is encased in a full metal jacket! Equipped with 4 wire leads that give the player endless tonal possibilities.
