I was doing a little research for insurance valuations on my hoard earlier. Blue book figures can be useful, but I like to look around for actual sales on Reverb, eBay, etc. I have had this little Gibson GA-5 Skylark amp since the middle 70s. I only paid like 10 bucks for it, and I assumed it was common and cheap yet. But I only saw one for sale out there, not even working, with a changed speaker too, and they were asking almost $800! Are these amps really worth that kind of money these days? It’s a nice sounding little amp, but Jeez! I hadn’t realized mine had been modified until recently, but frankly, I like this configuration better. Anyway, is there someone famous using one of these or something? How on earth can they even be asking that kind of money? Half that for a broken practice amp seems ridiculous! But it wouldn’t be the first time I’ve been shocked by how much stuff I thought was old junk is going for these days. Like my Maestro Bass Brassmaster. Crazy! But I digress. Can anyone tell me more about what would make this cool little amp such hot stuff?
