Hate to say it but if the only option for tubes becomes a very expensive, niche manufacture. I'll go digital when the time comes. I don't care for modelers etc and love turning on my amps and smelling them too...lol but now that it's just recreation in the basement, I couldn't justify that expense. But hey, the cheap, supposedly crap 34's I have in my MK V have lasted over 10 years, so there's that. I don't deny the modelers sound very good, I just like the immediate reaction and aesthetics of guitar to amp to speaker, add volume and enjoy your balls being stroked by sonic majesty. I'm counting on arthritis having sway before I give up tube amps anyway.
