I'm a Fender bass guy... I believe the Fender Bass is something that Ol' Leo got right
the first time. I sold my lovely vintage Jazz bass, because I have two others that
do what I need. And I didn't need a valuable old warhorse that might get me targeted
by guitar rustlers.
That old '66 had the best tone and the
most sustain of any instrument I've ever played. Truly a classic, but I actually don't
miss it much... here's why...
My two basses right now are:
a fretless Warmoth J-Bass licensed copy, which gives me a
great snarl and M-wah sound that I can't get with any other instrument:

I built this one out of parts I ordered and screwed together. The walnut P/G and
control cover were hand carved by me. Love this baby... I named her Luretta.
"Oh Luretta she's my bar room girl, wears them sevens on her sleeve.
Dances like a diamond shines, tells me lies I love to believe....
Her age is always thirty two, laughing' eyes of hazel hue.
Spends my money like water falls, loves me like I want her to...." --Townes Van Zandt
My other one is my 1997 ex Squier Precision Bass...
This one I rescued, and rebuilt from a derelict hulk that had moldered away
in a basement for years. I took it to Dave Collins, and he got the neck straight.
Then I gutted it and installed all new good quality parts. I named this one
Raven. She can take her place onstage alongside instruments costing ten times
as much, and not give up a thing. It's no longer a Squier bass, and I sanded off
the decal, and threw away the rusty plate with the serial number.
The Precision bass has been known as a one trick pony, from the days when
a bass was supposed to thump, and that's all. The J-Bass was invented to offer
bassists more tones. But this was long before anyone had any f/x to play
with. Now, with what we have available, the venerable P bass gives up
nothing... its basic good tone can be altered in many ways, or played
straight. It's hard to beat.
The MIC P-Bass is coated in Polyurethane, and is impervious to anything but
hammer blows and bullet hits. The hand built J-Bass is finished in Tung Oil,
and if I scratch it, I can just rub out the scratch, and apply a little more tung oil,
and disappearo. So both are dependable, easy to play, balance perfectly and
give great tone. Maybe they're a little heavier than an Ibanez SR650, but
I'm used to it, and regard the weight as part of the job.
