1. Black hardware- This screams 80's hair bands to me. The first time I saw black hardware was around that era, and the two will always be linked in my mind, even if I actually do
like some of that music. It just looks cheesy to me (required IMO)
2.Exessivly figured tops- Yup, they look great in your living room, or when you hold them in your hands, but when I see one being played in a "live" setting, they tend to look like someone puked on it from 25 feet away. Basicly too busy. It's nice to look at and all, but just looks wrong to me in a "working" environment. Again, IMO.
3. Plastic or Rubbery Knobs.- The exeption being Gibson, and Rickenbacker. I like them o.k. on them, but everything else... particularly high end stuff.... Just is a
giant turn off to me. I'd prefer chrome/nickel plated knobs on everything.
4.Overly long upper horns I understand that this is for ballance, particularly on ERB's, but I don't have to like the way it looks.

(exeption made for Rickenbacker, 'cause I like the way that looks.)
5.More than 21 Frets- makes for an awkward looking body shape due to the extended cutaway on the bottom to make access to the upper frets. Just another visual thing that I"m not fond of, however I understand the usefullness for those that need to play that high up the neck. I don't, so I'll stick with my opinon on htat.
6. Pencil thin necks- Just don't feel good in my hands. Again, personal preferance. I'd prefer at
least 1 5/8" across at the nut.
7. Active Electornics- I've never seen the need for it for what I do (YRMV). Just one more thing to go wrong. Batteries are for stompboxes IMO.
8.Difficult to get at Truss Rod- Self explanitory. I will put up with a hard to get at truss rod in an exeptional sounding instrument though. No excuse for it in a modern bass though. I actually prefer a headstock adjustable truss rod. The MIM Fender would be a good example of very easy to work with truss rod adjustment.
9.Satin Finished necks- Feels wrong to my hands. I came up playing what are now considered "Vintage" Fenders, and that's what feels right to me. Satin feels o.k. after they've been played in for a few years, but scratchy and stiff like an overly starched collar until then. YUCK!
10.Multiple pickups-Give me just one in the right spot and I'll be very happy.
