I'd like to share my experience on this: During like 36 years of playing music I found out that for what I want to sound like *good* tube amps *still* work better. For me the "Fender tone" is what I'm after. A good, nice and balanced clean tone. Why? I seem to be unable to get the sparkle and overtones I want to hear from solid state amps. I'd love too, but the tubes seem to add some overtones that solid state technology just doesn't seem to be able to do. Don't get me wrong, I used solid state amps from brands like Marshall, Yamaha, Session and Polytone over the years and lately the solid state preamp in my tech 21 fly rig. And I can get decent, good enough sounds that sit in the mix. I also tried the lightweight DV Mark little jazz and the Boss Katana and while I liked the tone I thought it is a bit bland and uninspiring. I also tried a kemper, but only with headphones so that may not be a realistic test. Recently we recorded a gig with the fly rig and in the mix the guitar (american standard tele) sounds really good. Only when I listened to the individual track I noticed there is something missing – IMHO. The tone is good enough and I liked it well enough while we were playing – there are only like the last five % that are missing (IMHO). Same when I did some home recordings lately – I tried the fly rig preamp first because it makes the process so easy. But after messing around with the controls for a while I just plugged into a humble blues jr. – not loud and instantly got something I liked with all the knobs at 12 o'clock except for master and reverb. So there still must be a (admittedly subtle) something that tube add to the tone that solid state and even digital still can't replicate. I wish they could but I would just love to go direct or have cheap and light combo that is able to produce the tone I really like - the full 100 %.
