hey dude; wel im using rectifires for over 2 years now and they still amaze me; they are great and its sound as the best – i think you propably can’t find something better i tried some marshalls (jcm900) and fender tonemasters but the mesa is the best of all the’re quite expensive but the are worth it and crate sucks really hard enough? okay bye : i’m gonna buy a half stack rig-any help on the differences or performance of mesa rectifiers,crate blue voodoo’s, and marshalls would be appreciated…
