My DSL stays at the band's rehearsal space several hours away and I've grown tired of having no amp here at the house. I also like knowing I have a decent backup. I have been following Jet City over the past few years and have been very impressed with their overall ethos. I got the chance to pick up a gently used (very gently) 50H over the Christmas holiday season for the low price of $230. It arrived with all stock tubes (power and pre) and I'd read enough about this head to know that those all need to come out. I fired it up anyway and, though I thought the overall tone was okay, it seemed thin and small sounding. At first I was thinking I would need to send it back. I came back a few hours later and decided to see if the things people write regarding the need to completely retube it were true. I had 5 JJ 12AX7's on hand, but I didn't have any 6L6's. I did have two short bottle Tung-Sol 5881's and decided to give them a try. My word what a difference the tube changes made. I am just out of my mind floored with how good this thing sounds now. I just keep it on the Crunch channel with the Pre on 6 and I'm exactly where I want to be. I love this amp! The head is a bit smaller than a comparable Marshall head. I think I may spring for a full size Hi-Watt style head box this summer to really make this thing look as killer as it sounds. Oh...and there's no inherent buzz or excessive noise with this one at all.
