I've played around with bass guitars on and off for years (seem to remember trading a Marshall 4x12 for a fretless about 20 years ago, but I've no recollection what happened to it), but I thought I'd give it a proper go.
So I've bought meself some cheap, basic gear - and I'm loving it! Haven't touched my PRS for days now, it's all about the bass!
The guitar is a cheap Evilbay "J & D" guitar - it's Chinese, and surprisingly OK. There were issues - the nut was cut too low, the fret ends were leathal, and the truss rod had been tightened to such a degree that the fretbaord was coming away a little from the neck (!) - but I'm OK with this sort of stuff, so I sorted it. It's now really playable. It sounds really good - I'm inexperienced with bass, but it sounds like I think it should. It's got an active circuit, and there's a good range of tones.
The amp is a "B-stock" Harley Benton affair from Thomann - it's OK, 12" speaker, decent enough EQ section. Together they actually sound pretty good - certainly good enough for my learning/recording purposes.
What's really interesting is trying to break my guitarists brain out of its rut and trying to think like a bass player. I'm finding that I'm thinking way more about song structure and the like.
And of course, now I'm gassing for nicer bass guitars and amplifiers...
