Keith.
I am a long time Pod user.
I tried a rack mount, but took it back the next day. It acted for some reason like a huge RF antenna.
Maybe a unit problem, but I haven't had the same problems with either my xt or xtLive. Less junk to pick up RF interference(?).
There's STILL no way to have your compressor BEFORE the volume pedal, and have it controllable to the degree that most compressor or overdrive users like it in the xt. Not unless you want to replace your Hilton with a "midi expression pedal". Not me, thanks..
The good news for me is that I don't use compression or OD on the PSG, and I use the xt Live VP when space allows doubling on tele, which allows the Compressor and Distortion before the xtLive pedal which I stand up and use when I play tele. On the xtPro and xt live the "volume" is knob controlled.
A little more hit and miss.
Dialing one in or "programming" it is a step by step process, and often live settings are not that easily matched in the basement "setup".
Once tweaked for live performance levels a simple "save button" locks your settings in. PLENTY of banks to save and name setting for ie: "MooseLowV" "JamBallsOut", "NeighbNghtmre" "Recording", etc. Dozens of places to save channel settings and differing defaults.
Using it after it's set up is TOTALLY EASY. Your presets don't change.
I read of the manual gives you the "models" of the compressors, delays, ODs, and MOST of the other functions. I don't see what the "Tube Preamp" is 24 bit digitally modelled after.
The "Vetta Comp" is said to be modelled after a "studio tube compressor", but is kind of hazy. It works better than the "blue or red" comps, and is separate from the other two, with a separate button.
I do know that The sound I've found for it is probably a lot more convincing for a simple 12Axxx than it is for the whole 5+ tube "tube amp modelers". Simple math.
If all I wanted was a "tube preamp" SS "pedal", I don't see how you could improve on the xt. Or at least I haven't heard it yet.
Even the Pocket Pod, which has 2.0/16bit guts has some pretty good effects, though the reverb is as sucky as peavey's.
Confused?
