There will always be a debate on tubes vs solid state. And yes, solid state is more accurate. IMHO that’s part of the problem.
Have a listen for yourself. And I’ll take a little controversial stance here… Yes, you can actually play your bass through a guitar amp. Contrary to what some sites are saying, they’re the same tubes. 12AX7, KT88, EL34, EL84, 6V6, and 6L6 tubes are insanely common. 12AX7 in particular are used in the pre-amp in both guitar and base a LOT, and 6L6 is often in the power amp for both.
No, you can’t really gig with a guitar amp (unless they have a PA). But you can practice at suitable volume. Check a few out.
My experience so far, on both my Gibson EB5 5-string and my Gibson SG:
Fender Custom Deluxe 1968 22W hates them. All it does is fart.
Orange OR15 15W hybrid likes them an awful lot.
The Supro Blues King 10 (5W) and 12 (15W) all tube both like them both an awful lot. It would probably like them more if I wasn’t playing humbuckers.
The Marshall CP900 all tube 100W loves them.
The Supro 40W Statesman and 35W Thunderbolt (which was actually designed for bass) think they died and went to heaven. The SG especially is damned amazing.
Yes, beginners, budgets, power (lol), features… All important. But so is tone. You need to enjoy what you’re doing, what you’re hearing, or you won’t play.
I have the a rumble 100, its a good amp. But it’s sterile. The EB5 sounds OK. The SG sounds bad (to the point where I can’t play the G string on it).
Just open up a little and try stuff maybe you normally wouldn’t. And enjoy yourself, regardless.
