So I always had the idea I liked slim necks, like the SR models from Ibanez have. However, after playing several basses (of course with extended range) I prefer thick necks. I don't know any brand at the moment that builds bass guitars with necks that are pretty solid. Any input in this?
Wishbasses have enormous necks. Fat nut widths and fat front to back. The Fender classic 50's and roadworn precisions have 1.75" nut widths and aren't that chunky front to back. They're one piece maple and rock solid.
Are you looking for a 4 string or ERB? Fender 50's P-basses (all the reissues) are generally thick necked.
Spector's have pretty hefty necks besides a few choice models. I think my Euro 4 is 1.65 at the nut. I love it and have no problem getting around with average size hands. It's the 35 scale jumbo frets I don't get along with. Skinny necks are good too. My Sterling SB14 is super slim and fast.
People are talking about nut width. Are you looking for a thick neck or a wide nut? A wide nut doesn't always mean a thick neck.
G&L have some beefy necks. Try M2000 Tribute. 1.75 and baseball bat roundness. Great neck and awesome bass that won't break the bank.
some of the G&L's have nice beefy necks. I like how they make you work for it a little more than a jazz neck.
Dang, those Wish Basses are cheap! Not exactly my cup of tea, but less $ than I expected. http://www.wishbass.com/homewishbasscom.html
Okay if 5-strings what you have in mind, the G&L L-2500 necks tend to be pretty thick and chunky (more so than Music Man). That might be worth your checking out.
Id say musicman stingrays have chunky necks. I was all about thin necks till I got my first musicman. now I can't even play thin j neck basses. there's just something about the mm neck that feels perfect.
Telecaster bass necks are pretty fat. As are 70s Fender P and J basses. I like fat too. The early 60s ones can be too flat for me. They are wide at the nut but thin from front to back. Same with the Fender '57 reissue Precision. Warmoth replacement necks are pretty chunky, especially the tele bass neck.
