Guitar Electrics Demystified

mad professorWhy I Am Writing This Blog

I used to post solutions and proven ideas in various guitar building Facebook Groups, but they got buried in the long toilet-roll threads, no headway was made, and as I had nothing else to contribute, I left the groups. So, I decided to put them here and to link to them.

I was building a kit electric Cigar Box Guitar and Dobro and noticed that most of the electrics used piezoelectric pickups (really made for buzzers) were very mismatched, giving rise to the usual thin tinny sound.

So, I designed & built some simple, cheap electronics to fix this and other problems and to share then all, for free.

Reactions have been mixed: Some like the tinny twang and don't see the point, some were baffled (probably my poor explanation), while yet others could not / would not solder and asked me to build circuits for them, but time does not allow this. This was only neant to be money saving, fun & educational.

Having finished my two guitars and having less distortion, no piezo 'quacking' (I finally used piezo film and electrets instead of piezo disks), and more bass. If any of these ideas are of use to somebody, then I have accomplished the goal.
