I'm currently trying out a fellow Gear Pager's Timmy, and yes, it is everything everybody says it is. I was almost afraid to try it as a post overdrive boost because I knew then I'd probably have to have say goodbye to my beloved AC Booster. Sure enough, I'll probably use one as a med. gain overdrive, and another as a dirty boost. Now all I'm afraid of is messing with the switches and finding out I have to buy a third one to replace my Burn Unit as well.
