Hi Jerry,

>differences (scoop, emphasis) between stack, combo and tube?
In theory, the Stack is supposed to simulate a typical English Marshall/Hiwatt/etc. amp with two 4x12" speaker "stacks," which the Combo is supposed to simulate a 2x12" combo amp like the Fender Twin or the Vox AC30. I'm not sure what Tube is supposed to simulate, but I find it to be the best of the three.
The LPF refers to the fact that most tube amps lose high end when they're overdriven at the output stage. The harder they're driven, the more the high end rolls off. This LPF is a fixed amount, unlike the VCF in the AN1x. It helps to take the edge off the sound. There is a balance that must be struck between the VCA level of the patch, the Gain setting of the tube simulation, and the LPF frequency to get the right tone.

I submitted a sound called GuitarSync in the lead "contest" last fall. It was a simulation of the Steve Vai/Eric Johnson/Yngwie Malmsteen style of over-the-top lead, and it uses the tube amp. Check it out. It works well with arpeggiated riffs in minor keys. One scene is mono for leads, and the other is poly for backing riffs.
