Hey, I'm starting my search for a new amp. The only amp I've owned was a little Samick SM-25B (80W - 1-10") that I bought out of ignorance. I have many many questions and searching has made me smarter but tired. Cab questions: 1) Is the definition of "bi-ampable" the ability to add a second cab? 2) What kind of cord do you use to connect an additional cab to a head or combo? 3) How does the power rating for a head INCREASE when a cab is added? Is it automatic or do you have to manually increase the wattage (ie. flip a switch)? Pre-amp/Power-amp questions: 4) Preamps and poweramps are only usable in a rack system? A combo or a head would already contain a pre-amp and power-amp. Misc. questions: 5) What kind of output jacks are needed for DI or monitors? Is it the XLR connector? 6) Jumping to 200W would not create a noticable difference with my current 80W amp, correct? 7) When will Joris finish his amp FAQ and make me smart?
