Small world! I have that exact one. Crate Vintage Club 30. Just put a new set of tubes in it. I bet that semi-hollow 335 with the humbuckers sounds really good through the clean channel. I play an Epiphone Casino hollowbody with P90s through mine and it's a rhythm machine.
I like the drive channel okay but there's waaay too much gain for what I like to play. Anything above "1" and it gets to fizzy. It's got a good compressed tone as long as I can keep that gain under control.
Have you experienced the channel switch circuit/volume level drop problem with yours yet? If so, FYI, the simple fix is to just plug your foot switch into its jack.
I love these amps. I got mine for $150 on craigslist and couldn't be happier.
