I don't play live anymore, but if I did, I'm fairly certain I'd want valve amps on stage. I'm a combo kind of guy, preferably 1X12 mic'd up, I've never got on with heads & cabs.
Recently, for several years, I was using modelling exclusively at home. Standalone units from Line6 and Vox. As I record with Boss standalone recorders, I also have all of Boss's guitar effects/modelling if I want it.
In the last year or so I've acquired two valve combos - Vox AC4TV and Laney CUB12. The Vox sounds well cool cranked, but I'll never be able to use it like that where I live (it also sounds somewhat boxy compared to the Laney). The Laney is extremely versatile and does good tones even at what I'd call low volumes (but the neighbours might not :lol:).
Basically, I'll use whatever it takes, none of it's wrong:
- For general practicing/noodling during sociable hours it's the Laney everytime now.
- For general practicing/noodling during unsociable hours it's a Vox Tonelab LE or a Line6 XT, whichever's plugged in at the time, through headphones. If I started at 8am, and 9am arrives and I liked what I was doing I'll switch the studio monitors on and take the headphones off (and not bother with the Laney).
- For bass practicing/noodling it's the Line6 XT with bass expansion through monitors or headphones (or the Laney's ok if I can't be bothered to plug the XT in).
- If I'm working something out songwriting/recording, and I'm plugged into a Boss recorder, I'll use the modelling on there.
- If I'm trying to record guitar "seriously" I'll use any of the above - whichever one gets the performance I think I want. Obviously, if it's unsociable hours, the valve amps are not available to me as an option. Modelling does add various artifacts to the sound. Sometimes this is distracting to me as a guitar player, but it's neither right nor wrong to most listeners. Sometimes the modellor does a far better job for the part than the valve amp.
Overall, I most enjoy playing the Laney cranked up to a reasonable volume. But that's only possible, on average, about one or two hours a week for me - not enough!!!
Otherwise, with any of the methods (except the Boss models maybe, which I don't like too much), I can always get the job done to a "good enough for rock and roll" level. Sometimes I can get something cooking on the Tonelab or XT that I much prefer to the Laney... next day I might not like it at all :lol:.
