I like some of the flavors my deville dishes out through the different amounts of distortion, but I can never really nail a really gainy sound without being mushy/too fat and not enough highs. I've now used around thirteen different guitars with the amp and I've played more than just my own deville so I hope that Helps. I REALLY WANT TO HEAR ABOUT A TUBESCREAMER!, NEVER HAD/PLAYED ONE BELIEVE IT OR NOT.
