i've been reading up/playing with amp refurbishing since make magazine issue 2 came out (with the article this old amp )and i've bene looking around online lately for building my own amps/effects/etc.

i was wondering if anyone knew of any books that were good to read for someone with a decent understanding of electronics, but mostly wants to learn what parts effect the tone in which ways, so as to learn how it actually works.

i hoped the people here might have read some of them and have an idea for what's god to read.  i've been looking around but haven't really found any books that really seem like what i want (and unfortunately there isn't much in this topic at the library)

thanks
