Does JB stand for Jeff Beck? Who the hell knows! One of the most popular high output humbuckers. Great for metal and rock. Dial back the volume for crystal clear clean tones. Dial it up for eyebrow melting scorched earth. Super versatile badass pickup. Works well in a charvel, jackson, strat, explorer, V or an SG. NEVER USED Don't buy one at LnM for $139.99 plus tax, buy this one for $100, take that $50 you saved and buy pack of darts and a sixer and rock TF outš¤š¤!! Do it. Will also trade for a Gibson 57 classic plus, Gibson Burstbucker 3 or a Dimarzio X2N. Letās see what you gotš¤š¤š¤
