I've go a tube works real tube overdrive pedal and it's as nasty as I need it. This has a 12ax7 (transistor) driven preamp tube which is effectively like adding another preamp stage. More stages, more gain. I've seen em on ebay from 49.00 to 75.00 bucks. I'm a big fan of low wattage tube amps and they're starting to make some good crunchy combos. Like the player above, tubes amps like to be cranked up. If you really want disortion, go to the music store and play through a Fender Hot Rod Deluxe. I like to play blues and classic rock and this thing was so hot I needed a warehouse to play it in. It had a clean, drive, and this insane thing called MORE drive, all three of which are footswitchable. It also has a bright switch that makes it even cleaner.

Sorry...Didn't mean to ramble on
