I have several hollow body/semi-hollow body basses; yes, they are nice, with a sound all their own. I don't consider them a replacement for my solid body basses, though; just the way to get the sound (and the playing experience) I want sometimes. However;
- If you want a "True" hollowbody bass - no tone block or anything in there - , they aren't quite as common as the semihollows. I have a few; Dano longhorn, Gretsch Broadkaster, and an old Epi EA-260, among others. Honestly, other than being a Gretsch, Dano, etc., I don't really notice any real difference between hollows vs. semis. Just boils down to which bass feels best to you, IMO.
- Feedback? Honestly, unless it's a true hollowbody with single-coil pickups, it shouldn't be much of a problem. And it's been a long time since anybody (besides Danelectro) made one of those. The tone block, and humbucker pickups, were made to prevent that problem, and they do a good job. Personally, I
can make the Epi feed back - a little - but I have to work at it. the others? Haven't managed it yet. You might manage it with, say, Lemmy's sound rig, but otherwise? Probably not.
So, buy whichever one feels and play the best, and that you just can't stand to be without. By the way; those Kays
do look nice; no leftys, unfortunately...
