It sounds like a great little practice amp. You can always mic it (if needed) at bigger venues. Weight is a big factor for me so I would rather have a good little grab and go than a Marshall half stack. Most tubers putting out 50watts weigh about 40 or more pounds, so your little 20 pounder sounds like a good way to go. If you like the sound of the Vox amps, I say go for it!
