Re: Bass amps. Whats your rig?
My CBX Ellefson 5-string feels nearly identical to my '93 Concert V 5-string. The body of the Ellefson is lighter, but the neck profile and playability is very nice.
The Concert V has the Kahler bridge with adjustable string spacing, and the CBX has a fixed-width bridge, but the strings are very close together, about where I keep the Kahler set.
Only thing I'd change about the CBX is to space the active knobs out a bit more, as they're right on top of each other.
As for amps, right now I've only got a Bass POD and a Fender Rumble practice amp. For recording I run through the POD, a clean patch in my ADA MP-1, which feeds into a patch I made in my Digitech TSR-12, and a Bassman patch in my Digitech 1101. I also have a patch in my Line6 AM-4 that has just a hint of breakup, to give it a little more punch.
Back when I had pedals instead of rack gear, the only distortion pedal I liked for bass was the Ibanez LA Metal. Nice smooth, Lemmy-like distortion without a lot of high-end mess. Wasn't flabby or farty, but very smooth. Sucked for guitar, though.
I have a Sound Sculpture Switchblade 8 which lets me send one input signal to up to 8 different targets, so I can run through all my stuff at once and mix it with a Rolls RM203x Line Mixer. Each component gives a little something to the overall tone, but no single unit can (so far) give me the tone I'm looking for. The overall bass sound practically mixes itself with the various guitar tones I use, from Megadeth-ish to Iommi-ish to Priest-ish, the bass tone always seems to fit. I get a ringing, punchy tone like Ellefson, the "rumbling and clanky" tone of Steve Harris, the Geezer Butler driven tone, and Ian Hill's rock-solid thump, all depending on what tone the guitars have.
Many years ago I got an old Ampeg B25B head, but never had a cabinet for it. It's sitting in a storage unit across town right now, but I hope to get it out one of these days and get tubes for it, and a cabinet.
