Originally it was a Traben Element. An already awesome bass. But me being me, I had to tweak it some more.
First is the obvious. Cosmetics, the graphic work. All done with vinyl decals and pinstripe tape. Actually, in person it looks a lot sleeker. The camera makes the edges of the tape more 'obvious' than they actually are, if that makes sense.
As for actual hardware upgrades, the low E tuning peg has been replaced with a Hipshot Bass Xtender.
Electronically, I replaced the stock Musicman style humbucker with a Seymour Duncan SMB-4D Ceramic (Thanx Barebones for the awesome, super speedy transaction!. Gives a little more grind and power than the stock pickup. Especially powerful when the coils are wired in series... how I keep it. Also, you probably notice the black electrical tape on top of the pickup. Thats because I like to keep it moderately close to the strings for a powerful output, but when I play hard, fingerstyle it slams the strings against the exposed metal pole pieces, which when combined with a heavy overdrive (as I use like 90% of the time) makes for a loud 'clack/pop' sound that is well... really annoying. Well, the tape over the polepieces stops that, but doesn't otherwise effect the tone at all.
