My first build was something called the 'Noisy Cricket'. It could work on a 9V, but I opted to use a Boss power supply. Sounds great, and gets a little dirty as your turn it up.
I once took it to an audition with a little 1x8 Orange cab. I know it's just one watt (tops), but I thought it was going to be a low-key audition. The guy was pumping backing tracks through a HUGE PA. I pretty much pegged that little thing, and it just about kept up. However, he said he wanted me to play 'cleaner'... I told him to turn down his PA
Look it up. Fun little amp to build.
I think I have a short demo on YouTube of me using it. But, I used a dirt box the whole time..
