Hey everyone, I was wondering if anyone knew of a good website/book that explained how amps and effects work.

I'm trying to get some background information to understand how everything works before I start spending money getting a touring rig together.

Right now I have a 4x10 Hot Rod Deville that is stock except for the tubes, so if anyone also knows of a good tube/speaker combo let me in on it (mostly texas blues type sound but need to be able to play in the sound of everything else)
Gibson Les Paul Studio
Highway One Telecaster
Dean Evo
Mesa F-50
Laney GH50L
Vox AC30 C2
Ampeg V2
