The tones im am looking for are blink 182 tones through to pantera metallica type stuff
Blink 182, no problem... I think they use rectifiers
Metallica, the newer stuff from the last 10 years would be no problem since they also used Rectifiers on some of their stuff.. But the older stuff (like the Black album back) you won't be able to get quite as "tight" of a chunking sound but it will be really close, the Mark series I hear are good for that.
Pantera, once again you won't be able to get quite as "tight" of a chunk but you will be able to get some pretty aggressive tones out of it.
The rectifier series (Singel, Dual, Triple, Tremoverb, Rectoverb, and Road King) all have basically the same sounds in them, but each have a few other bells and whistles over the next (with the single recto being on the bottom of the food chain there- but by no meas less of an amp, just less options) but some people like the Single recto better than all the rest and say it sounds more aggressive and has better cleans, but thats opinion. I really liked my Rectoverb (single with reverb) better than my Triple.
Just remember, tone is in the ear of the player and what I say from my expierence may be the exact opposite as the next post, but for the most part the Rectifier series of amps don't have a real tight low end but are still (I hate this term), Nu-Metal and pop metal masters! Creed, Incubus, Puddle of Mudd, Blink 182, Dream Theatre, Nickelback.. to name a few.
Several people around here have clips of one in action, you may want to check out some clips to make sure the rectifier is the amp for you and if it's not I'm sure someone can point you on to which amp to get those sounds. The Mark III and IV comes to mind as well as the new F-Series. The Rectifier was the amp for me, and I think you'll find some tones you like it.
Check out my short sound clips at www.guitartest.moonfruit.com and go to the "Road King Clips" page. The top one is all Rectifier in the Vintage mode.
