Koss-301 MXV P.A.F. Pickup Repros.

顧名思義！”Koss” 代表了著名的英國Blues Rock 結他手 Paul Kossoff，而 “301” 則代表了50年代 Gibson 用來製作 guitar pickup 的其中一部古老機器 “Meteor ME 301” coil winder！

Koss-301 MXV 是從 Paul Kossoff 所用的1959 vintage Gibson Les Paul (a.k.a.“Koss Burst”) 所搭載的PAF Pickups，再經由此結他的現任擁有者 Kris Blakely 所監督下複製而來。

低電阻和豐富飽滿的 Neck pickup音色但絕不會感覺 “Muddy”、Bridge pickup 比一般的vintage PAF 略為大輸出卻仍然保持清晰的音色！

線圈使用 Gibson Kalamazoo工廠時代的 ”Meteor ME-301” 古早 coil winder 製作，再結合由 ThroBak 所制定復古配方的長 Alnico 2 磁鐵而成！完美地把 Paul Kossoff 經典的 “Koss Burst” 音色再次重現出來！

Koss-301 MXV Details

How do you capture classic Paul Kossoff tone in a P.A.F. replica? Well the dream case scenario would be access to the very guitar once owned by Koss. When Kris Blakely, current owner of the Kossoff Burst, contacted ThroBak to make a set of Kossoff repro pickups, that dream became a reality. Under the supervision of Kris Blakely we were able to take careful gauss and resistance measurements and closely inspect the uncovered vintage PAF pickups in the Kossoff Burst. By applying this information to the prototype pickups and comparing them both in real time and in recorded tests against the Kossoff Burst, we feel we have nailed the P.A.F. tone of the pickups in the Kossoff Burst and made a set worthy of the guitar's legacy. The ThroBak Koss-301 MXV. A set with bridge pickup tones that are surprisingly hot and searing given the low resistance and a neck pickup tone that is rich and full.

As part of the research required to do a repro correctly we discovered some amazing details about the Kossoff PAF's that explain their distinctive tone. These details also led us to some interesting connections and mysteries that are shared with another legendary guitar, the Peter Green Burst, "Greeny".
