I was just searching around the much hated ebay and came across a Gallien Krueger 300B. The add claims it was from the mid 70's, but I've never heard anything mentioned about one here. It's bidding for around $300 now, and I'm wondering if I'm a fan of the GK tone would it be a wise buy? Any opinions of it's performance or tone? I understand it may need a little tlc because of its age, but it might just be worth it. Thanks!
