I've done a few electronic DIY kits in the past. I'm an amateur, I build because I love building and making. I'm really interested in preamps and classic tubes amps. I would like to build a preamp for harmonica players so they can overdrive in blues music. Can anyone give my a good kickstart reading list. Could be on the web or in book form. Nice to meet you all. Skunkie you're building a community here, great work.
