Hello all, I thought I would post my first build here as it really isn't a cigar box guitar, even though it does have 3 strings tuned Gdg.
I picked up a bit of dry ghost gum that came off a tree with the recent winds and decided it should be a guitar.
I hit the wood with a chainsaw, router and sander, sealed it with linseed oil and made it into a 3 string guitar.
The guitar also sports a homemade pick up and built in valve preamplifier.
A 6GM8 dual triode is used as the bridge on the redgum guitar and also as a switchable preamp tube running from a 6v supply.
The heater and plates of the tube run directly from a 6v lithium camera battery clipped in on the end of the guitar.
I have added in an on-off/ bypass knob also.
The knob turns on the preamp, and when turned off bypasses the circuit so the pick-up can run unboosted.
All the wiring is enamel wire to keep the real DIY look to this thing going, I have used small ceramic caps, which I normally shy away from but used them in this guitar as they seem to add a little extra something to the sound.
The output from the guitar has been boosted dramatically at least 6 fold making it a much more useable instrument and something I will have alot of fun messing around with.
I have posted pics on facebook;

Hi Mark,
Second that very cool. Do you mind sharing the schematics for the preamp?
Cheers
