I have the original one with fender alnico blue. I don't quite love the sound, but when combined with my Vox AC 30, I get some nice sounds. I love the speakers, though. I sometimes use them as an extension cab for my AC30. They sound great.
I have owned this amp for 10 years and it has always been very reliable. Wiring, considering its age, is great. There is a bit of volume indifference between 1 and 2 (large jump) but again, considering its age, and the only issue, that's actually a testament to the quality.
