Old thread I know but I have one of the last ones made. This one sounded really great but had a popping noise I wasn't sure about. Sad thing was I took it and an Octa-switch in on a trade for a replica I made. I was a little disappointed about the popping noise. The guy who traded me was a stand up guy and said he'd make it right for me if I wanted to trade back. But I didn't want to trade back, I liked the amp except for the popping. I had an old set of Mullards sitting around and changed the power tubes with them and BAM!!! The amp came alive. It went from an amp I liked to an amp I love. Everyone who's heard it lately has been very impress with it I've had a few offers to buy it from me. Its the best trade I've done besides my Bogner Duende head. I like both equally, just for different reasons.
