Hey guys! I am a big Dave Mustaine fan (kinda obsessive about little details right now) and recently bought a 1999 Jackson KV1 (with LSR tuners) which is currently in transit. So, while I was researching about Dave's guitars, watching a few interviews (new ones), I kinda compiled what he has used over the years, but there are also some things that I don't know about and would like more information on. So, here goes nothing. Dave began with Megadeth in 1983, played his BC Rich Bich which had a DiMarzio Super Distortion in the bridge (I assume, correct me if I'm wrong) and a Bill Lawrence pickup in the neck, which I assume is an L500XL which later appeared in his KV Pro signature models. Then he switched to Jackson guitars after Peace Sells came out in 1986. I saw the Jackson Guitar Palace Mastermind tribute site to Dave Mustaine which has a ton of information on his guitars. So, lots of information is from there. http://www.jacksonguitarpalace.com/d...ne/guitars.htm So, he apparently used some stock Jackson pickups around 88-90, and the work order for his Black King V with a Megadeth logo King V says that he ordered it with J-80 in the bridge, and a J-50N in the neck. Does anyone have more information on these pickups? And, I wonder how did the 5 way in such guitars work? However, he switched to Seymour Duncans before Rust in Peace, and the guitar currently (I assume) has a JB-4 in the bridge (which will remain constant until he switches to the signature Livewire set), and again, a Bill Lawrence L500XL in the neck. What's the best replacement for such an L500XL pickup in the modern age? Next, we move on to his Pro series models which were made between 1993-1995, and they came with a Jackson J-92C in the bridge and an L500XL in the neck. What's the J-92C? Best would if somoene around has a stock KV Pro from that Era, to just see what pickups are in there haha Next, in 1996, Jackson came out with the KV1. It came with (according to the catalogs) a Seymour Duncan TB-5 in the bridge and an SH-4 in the neck. However, the KVs did have the TB-4 in the bridge instead, since mine is stock and I had the previous owner look into what is in there. In 1999, Jackson and Dave came out with the Y2KV which again had the same Dual JB combination. Later, in 2004, when Dave switched to ESP guitars, his DV8s came with a JB-4 and Jazz set. Which became the basis of his signature Livewire set in 2006, which has been on all of his Deans ever since. Now, as many of us know, Seymour Duncan and Dave Mustaine came out with the Thrash Factor set last year, which is Dave's JB-4 bridge pickup and a '59 in the neck!? Since when did Dave start favouring a '59 in the neck? And, what's the difference between a usual JB-4 and the Thrash Factor? Fun fact - Dave's Number 1 Jackson, still currently in his position has the infamous Seymour Duncan in the bridge, and a Livewire in the neck!? Now how does that work? And, why? And, for the final question, with all the different pickups he has used in the neck position over the years, an L500XL, SH-4, Jazz, Livewire (and now '59, apparently), and the JB being constantly there in the bridge throughout, does he even use the neck pickup, ever? I've tried to find live videos of songs I suspect he might be, but he uses his bridge pickup for all the clean parts that he rarely plays (Trust, In My Darkest Hour, recently, My Last Words), and every time I see him solo, the switch is in the bridge position. So, why confuse/troll us Dave? What are your opinions? Any Megadeth fans in the house?
