Thanks Marcus. I also have a Variax 500, which I REALLY like. It's been a great guitar that I got cheap when they were discontinuing the 500 model. I really like the sounds I get out of the 500 with the Lester model that emulates the Les Paul Jr. It just sounds really smooth to me, especially with a decent distortion. I have a real Tele, which barely gets played because of some not-so-great frets and I also have the 5-string Variax Bass, which I also like for all the tone options it provides.
The USB 1.x interface on the UX2 has never been an issue with me for a number of reasons.
1. I really only use it for monitoring effects. My real audio recording goes through my Layla 3G. This allows me to crank the latency in Sonar and still get really fast feedback on the effects/models. This is less important now than when I got the UX a few years ago, but still pertains when I'm woking on something that doesn't fare well at low latency.
2. It's just a single/stero device anyway and the bandwidth of USB 1.x is plenty for this. In this case, it wouldn't really matter if it was USB2.0, as that extra bandwidth would never get used. If it were an 8 channel device or something (which it couldn't be anyway), then it would obviously be a problem. But not here.
3. I use the PODFarm plugin now, which allows me to get at all of the models from inside of Sonar - still have the latency to deal with, but as I said this is less of an issue now - I still reserve this as mostly a mix-down thing anyway. I don't have the newest version of this plug, which would allow me to split out the individual effects of the PODFarm, so I could access the delays and such without having to load up a whole preset. This would help a lot, but I'm holding out on this to see what the new guitar fx models in Sonar X2 are like. I may not need the PODFarm at all, or at least not the upgrade, which is something like $100- as much as the upgrade to X2 would be for me! But I really do like the delay modules that are in the PODFarm better than anything else I've used (that came with Sonar).
Thanks again for the feedback.
