I have both and honestly my solid state amps get more play time than my valve amp. However I love them equally...
When I do fire up my tube Marshall, I hear how noisy it is compared to my solid state's. The only reason I still have it is because I cannot sell it.
The Line 6 HD-75 through (4) Jackson 4x12 Cabinets (with Eminence Speakers, these are 200 watt cabs) nothing I have ever played - not even my Marshall SLP - comes close to the tone, clarity and punch they give me.
I've played alongside guys with SIR modded Marshalls and multiple cabinets and I can dial in more tonal possibilities with my Line 6 junk rig and its dead quiet, doesnt overheat out in the sun at outdoor venues and doesn't feedback even when cranked
And my entire rig - That's (2) HD-75 heads and (4) Jackson 4x12 Cabinets -all cost less than $550.00.
I used to brag about how much I spent on some vintage Marshall cabinet loaded with some rare Greenbacks, or how much I spent to get this certain JTM-45 Marshall head that Angus Young used on Highway to Hell.
Gone are the days when I will waste $2,000 to $3,000 on an amp - like I did on my Marshall JVM-410C - to wonder why it wasn't more versatile for the price.
And I've played all the other's on my quest too...Randall, Mesa, Orange, Peavey, Bugera, Overdrive Specials, Laney, Bogner, Hughes and Kettner, Wizard, Sunn, Fender, Vox, Friedman, and the list could just go on and on and on.
For studio recording, my Blackstar ID-CORE 100watt is the dedicated house amp and it is seldom - if ever unhooked from my DAW - because it just works so well and covers such a wide range of tones.
FWIW anyways...
