Well, am giving up on my rather exotic quest for a small lightweight bass combo with a speaker-out jack... Have decided instead to go for a more standard type of 1x8 practice combo. And I don't really want it for practice either, as I have my larger Ampeg home stuff for that. -What I'd mostly use it for would be at an acoustic garage jam, and also at a church performance with one acoustic guitarist, a tambourine player, and 3 to 4 folk singers.
IMO the PJB dbl 4 stuff is real nice, but a bit costly? (And very
low to the ground for this bad back guy too...

) I also seriously considered the Vox B50 bass combo, but some of the demos I've heard of it's sound have turned me off..
~So far, what is leading in my search is the Orange Crush 25W 108. ~I've heard lot's of good things about the Orange sound; it's not overly pricey, has a built-in tuner, and at 22lbs is a manageable size that's only a little over my 18lb limit. And I feel it's 25W sh be enough for my needs in this situation. Any other suggestions re 1x8 combos (and/or opinions re the Orange) will be greatly appreciated...
