G&L L2000. If there's a bass tone in your head, odds are good you can find it somewhere in an L2000. The Tribute series sound great - but I found many of them to be considerably heavier on the strap than their US made cousins. If weight is a concern it's something to be aware of when shopping for a Tribute.
Spector - Generally a joy to own and play. Unapologetically modern looks and tone and somewhat edgy sounding. Nothing at all like a Fender. I own a Spector fiver (my only fiver) and didn't find the string spacing to be an issue.
Gibson/Epiphone (I actually prefer the Epiphone) TBird. It's its own thing. You like it or you don't. Definitely not the Fender sound. I like it a lot.
Peavey T-20 - no longer made and very reasonably priced (currently around $450) on the used market. Single Peavey super-ferrite pickup and fast comfortable neck. None of the control complexity or weight issues some folks have with its heftier cousin the T-40. Strung with a set of Rotosounds and set up for low action it's one of my goto basses for Prog.
Gretsch Junior Jet - small, inexpensive ($300 new!), great sounding, cool retro looks, well made, and flat out fun to play. I prefer the discontinued first version with the single TV Jones designed pickup in the sweet spot over the newer dual pickup Gretsch minibucker version. The first version is well worth hunting down on EBay or Reverb. But both sound really good and are worth checking out IMO.
This one's a long shot: the Guild Starfire. ($1100 new, $800 used) If that creamy sorta jazzy mid to late 60s style "thwump" and "fwoom" thing appeals to you, a Starfire will get it for you. If a Spector is more your thing then the Spector Spectorcore semi-hollow (available as 4 and 5 string fretted and fretless/$1200 new, $750-850 used) is another good choice. Similar in sound to the Starfire. But it still has that unmistakable Spector tone and timbre going for it. I came very close to buying a Spectorcore fretless until a truly rare opportunity for something else unexpected came up and I went in a different direction.
That's all I got for suggestions. ()
That is a lot of information.... Thank you! I took the time to read your post a few times. So far, the brand that i am the most curious about his spector...
