I've owned (and still own) a number of different tube amps. Moost recently a DRRI, original Blues Deluxe, and an Egnater. I've also had Marshalls, a Super Reverb, etc., etc. I'm currently gigging with a Vox AD50. The tweed setting doesn't sound
exactly like the Blues Deluxe, but it's really close, as are almost all of the models. For club gigs, close is usually all you need.
I had an interesting gig a couple of weeks ago. I did a gig with a guitar player friend of mine. He brought his '56 toploader Tele and a '66 bf Pro Reverb to the gig. I brought my Squier Standard Tele and the Vox. At the end of the gig he asked me why my rig sounded better than his.
Modeling technology has come a long way in recent years. It's still not 100%, but for most applications it will get the job done. I gig a lot, which is hard on gear, so I'd rather beat the crap out of my $300 Vox than my $2,000 Eggy.
