Recently Ive decided to upgrade my rig, Ive been playing guitar for some time now and have the money for it, so the first thing I did was buy myself a new guitar, I went out and tried different types and bought the one that I liked best, a Gibson SG. Ok, the next step? The amp, Im looking something near the 1K~1.2K limit, no more; my budget is not allowing me. Right now Im considering: Peavey 5150(6505) combo Traynor custom valve 80 2x12 Fenders I play rock, and these were the amps I audition my guitar when I bought it, Im looking for an amp that can deliver loud cleans and has a nice crunch in the overdrive channel, (two channels might be good and effects loop, NOT MANDATORY as is the case of the peavey); I play with effects too, my current pedal board has a SD-1, big muff and a DOD multifx that I will upgrade after the amp, I need some chorus, delay and phase in my rig, right now Im playing through a little Crate amp that doesnt cut through the drummers loud playing. Now you all know what I have and what I want, any suggestion will be appreciated. PS: if you can explain something about the different sounds of tube amps, like the difference between 6L6s or EL34s or any other tubes and post some references like sound clips or suggest any recordings, I will thank you, I know some of this may be achieved through the search engine, but couldnt find it that easily.
