I was happy with how my very first CBG turned out...but I wasn't SATISFIED with it. Well NOW I am! Only did a few "tweaks" to it, but it turned out AMAZING, IMHO. I removed the electric guitar strings and part extra light acoustic strings, which sound MUCH better. Before installing the strings, I glued up the two outer string holes and re-drilled them, making them more "spread out".
BUT! Before I put the new strings on, I opened her up and installed my first piezo transducer/volume/audio jack setup. I printed out the basic schematic from Ted's website for the piezo/volume/jack layout. I went "old school" and bought my parts from Radio Shack. After I "rescued" the transducer from it's plastic prison, I glued it to the lid with Gorilla Super Glue and installed the volume pot (an audio tapered pot) and 1/4" audio jack. The only real problem I ran into was that the wood was actually TOO THICK to use the nuts and washers that came with the pot and jack. So I wound up super gluing those into place, too. (I love me some Gorilla Super Glue.) The knobs I bought from Guitar Center didn't fit the volume pot either, so I've still gotta find a knob for the CBG. :(
Once I had the electrics wired up, I tested it before stringing it up. I purchased a Danelectro "Honeytone" mini amp and plugged the guitar into it. As soon as I started tapping the top of the box and got the "stompbox" sound from the amp, a big smile ran across my face. :)
I quickly finished up the re-build and re-strung the CBG. As soon as I plugged it back into the amp I knew it was gonna ROCK, because it was already picking up every little vibration of the strings. Wasn't even in tune, but I happily plucked the strings and ran the glass slide up and down the strings. Much to the chagrin of my wife. LOL! I was simply AMAZED at how well the piezo worked as a pickup! Whoever came up with that idea was a f**king genius! ;)
As soon as I get it in "tune" and have had the chance to play around with it some, I'll make a short video to show it off and post it.
