Honestly, the best amp I have ever had. It just sounds so good, inspires me every time I play through it. A heavy little beast but so worth it. I can't imagine being without it. I did a review of this amp in the reviews section, check it out!
My first good tube amp was an Engl (German company). I'm always thinking about buying one again, but
a) they are not cheap (but worth it, I know ...)
b) I feel the Fender I have lends itself a bit better to Blues playing than an Engl ... but the new line of Engl Retro Combos might change that.
(still, I carry an Engl Tubetoner - 4channel tube floor preamp with frequency corrected mixing console output - as a backup to every gig)
