My drummer beats the skins like they owe him money, so I think I am an authority on this - specially considering that I've owned three of the four amps in question.
1.
Cyber Deluxe - don't waste your money. When you crank it, there is absolutely no body. It might be a terrific amp for recording or noodling around in the woodshed, but that's where it's authenticity and character end. Fender needs to stick with what they're good at - classics, not cutting edge technology. I do understand that the Cyber Twin is a great amp - but it has tubes.
2. Hot Rod Deluxe - I'm not a tube snob. As a matter of fact it wasn't until about a year ago that I really started using tube amps - pretty pathetic I know. There's a guy in a local act in my city who has been using one of these for the last three years - used in conjunction with his pedal board, he has a really nice tone and definitely cuts through the mix - this amp gets my vote.
3. Flextone - Just like the cyber, unless you're going to run it through the board, mic it, use it in low level settings while recording, it just won't cut it in a live situation. However, the Flextones definitely have "bang for the buck" and I prefer the sound of the Line 6 stuff to Fender's modelling amps.
4. Valvetronic - never heard of it or heard it, so I can't comment.
BTW, the Marshall Guv'nor sounds great through a clean tube amp.
Good luck!
