I've not tried an Axe-FX, I'm down in the cheaper seats with a Vox Tonelab, but fairly comfortable there.
I am one of the "modelling is cool" dudes on here. But I have to say though, although I happily use a modellor for recording (and I expect no-one except us guitar anoraks to be able to tell the difference :lol:) and for noodling sometimes, I much MUCH prefer playing through a valve amp that is voiced right for the volume I can use it at.
When I joined this forum I was using modelling exclusively, Line6 first, then the Tonelab. This was because I couldn't use my old gigging amp from 20 years ago in the flat we live in. That amp was, and is, gorgeous. But at "flat-friendly volumes" it sounds cr@p compared to modelling.
I was new to and learning modelling at the time, and was utterly amazed at what you can get out of it. Then a while back I got a small valve amp, and I am so much happier playing through that... it's not "better", just "different"... but it is more satisfying for the player.
For recording, at least the stuff I do, I'm convinced both amp or modelling methods can give equally effective results. On the day, one or the other is usually an easier method to achieve the desired result, so I do whatever it takes.
If I was playing live... I would be prepared to use a modellor... but I'd much rather have a valve amp.
I'm getting the impression that many people who've dabbled in modelling have gone through the same journey as me. Starts off with "Oh YEAH fab...", and then eventually you accept it for what it is, use it where it works... and then play a valve amp when you can! :lol:
I'd be wary of dumping both amps for a modellor, especially one that expensive. And especially, even though I'm a modelling fan, I would not replace a working valve amp gig-rig with modelling at the moment. If I wasn't happy with the valve amp rig, I might explore the modelling option, but I'd probably end up getting another valve amp instead at the moment.
Yep, tough choice...
I think Toe-Knee's absolutely right, see if you can try it out and see for yourself. However, while you're trying it, do be aware that the initial flexibility and general amazing-ness of modelling is very enticing, but it does seem to wear off after a while!
