I always heard the J/B refereed to Jeff Beck. Well I called Duncan the other day in regards to a wiring problem and somewhere in the conversation the J/B came up and the employee at Seymour Duncan told me it doesn't stand for Jeff Beck... Its stands for "Jazz" and "Blues"! He went on to say on there website under the SH-4 JB description/specs they don't even list him as a user of the pickup. In fact not one of his signature Strats even uses Seymour Duncans let alone the SH-4 JB. Nor does his signature Gibson Les Paul 1954 Custom that Musicians Friend has for 25,000.00! Yes, thats 25 thousand not 25 hundred!
