Details:

That's just the way they did it. You can get Marshall or Fender just not crazy liquid gain. With the low- voltage this operates that may not ever have to happen. Inside, the12AX7 tube is hot glued into its socket.

Should you ever need to replace the tube hot glue easily peels off. Racks got bounced around a lot. The master volume gets slightly scratchy towards the end of its travel, but it is not bad. Not ultrahigh gain but very smooth, unable tube pre amp.

1989 was the year this made. No known issues.
