Like Emohawk just wrote, the Tramp may be a little more challenging, but well worth the trouble.
The Tramp completed recently was my first build. I wrote Stephen before choosing it and he told me it could be built by a beginner like me.
So I went with the the Tramp and do not regret my decision. It is a very versatile amp with adequate volume to play at home with the 6V6 tube that comes with the kit. The beauty of it is that you can get wonderful distortion and blues tones at bedroom level.
As for the build, it went well. The instructions are good and I took my time.
I was tempted by the tweed Deluxe also... maybe next time.
