I've recently been looking hard at the Bassman 100/135. I'm curious what a reasonable price range might be for these amps. I've seen a few 100s recently go for around $420 on ebay. Likewise I've seen a few of these amps fail to get a hit with starting bids around $500 to $550. I figure also that if I buy one I'm gonna have to then shell out for new caps and possibly new tubes as well. And while you're at it, what's a reasonable range for Ampeg v-4s? Seems to me like I've seen these go for maybe a hundred dollars or so higher than the Fenders. Sorry if this topic is redundant but I did a search on this and couldn't find much on current prices. Thanks in advance. Oh yeah, I'm mainly just looking for a head and not the full rig with cab. Thanks.
