1990 50watt Kitty Hawk Junior, all-valve, 2 x EL34s. I'm not being flippant for a change - the amp is so well designed (esp. the front end) that satisfying and natural-sounding overdrive sounds are available almost at unplugged acoustic guitar volumes. The icing on the cake is that it's seriously loud when needed - I've had the master higher than 5. I'd love a spare!
