I'm thinking about a trade deal with a local shop for an amp and speakers. I've pretty much settled on a pair of 1x12's (Aguilar or equivalent) but have several amp possibilities, and others not at the shop, that interest me. I'd welcome any comment pro, or especially con, on any of the amps on my list. I know the power ratings cover a wide range, so setting that aside, do you have any strong feelings about any of these. I should probably add that I'm playing 4 string basses, 90% fingerstyle, favor more of an old school tone and my aging back places a premium on light weight. EA iAmp350 or iAmp500 (I've had both and the 500 would be my 1st choice, but they're hard to locate used) Eden WT-400, WT-405, WT-550 (I've had a WT-550 and regret letting it go) Ampeg PortaBass (No experience with these or Ampeg in general, the 250 is probably underpowered for my needs) Mesa Walkabout (No experience with these or Mesa in general, but I've heard a lot of good things about the Walkabouts.) I have done searches on these in this forum, so I guess the main thing I'm looking for are comments personal experiences with these amps, especially if there's a reason to avoid any of them. If there's one I haven't mentioned that's worth considering, please mention it.
