the gibson les paul handbook

What is the best introduction to my line 6 PODxt Live?
I recently bought a Line 6 PODxt Live, and I use a Gibson Les Paul Studio through a Marshall MG50DFX that. There are many parameters in the output mode my PODXT I have no idea how to make it work performance with this amplifier! Can anyone … please? I have read the "pilot" use "and is simply not helpful. Thanks in advance:)
Sell the car and the amplifier and buy a nicer amp. The station and its amplifier both have a good rivalry. When put together, twice the emulationess. I can minimize or ignore the speaker and amplifier emaultion the car, and just use the form on effects. Ask the basket in the effects loop. I had many problems with POD XT Live Amp MG100 and my friends also trying to get a good sound. This a headache for such distance from the joy of playing.
Gibson Sg, better then the Gibson les paul?
