I have built a couple of cbg's now acoustic with piezo pick ups, through neck with cut outs.
Was thinking of going the next step and building one with a "humbucker" or some form of magnetic pick ups as in "normal" guitars.
Now do i make it semi acoustic with pick ups or make the 'box" more solid type with more bracing?
Does any one have pics of internals during build? And any building tips.whats best seal box? or leave it to close with latches? does this effect sound on these type of builds?
Thanks in advance for your comments

I learned a few things from you post ,,,,,,,, again,,,,,,,,,,
http://www.cigarboxnation.com/video/comparing-cbg-pickups To wire up I find the Seymour Duncan schematics the easiest to follow - you just substitute a piezo for one of the magnetic pups. This and other diagrams are are linked here
http://www.cigarboxnation.com/group/cbgwiringelectronics/forum/topi... I cannot find the link but previously another member used a blend pot to link the magnetic and piezo pups to add more tonal control. inside of the box is here (it is a 35mm photoslide box because it is hard to find cigar boxes in the UK)
To fix the lid down I use decorative hinges because even with 8 gauge electric strings the tension starts to bow the lid a bit and this way it is easy to open the lid later if needed. Regarding bracing the group smokehouse guitars has a section on it with regard to 6 string guitars http://www.cigarboxnation.com/group/smokehouseguitars/forum/topics/... It also has a series of tutorials on how to build from scratch which are well worth a read through. I have yet to make a 3 or 4 string instrument yet so I don't know what bracing you need for these. Kind regards, David
This is true in CBGs.... a piezo equiped CBG will have a more acoustic sounding tone when amped, than a similarly build CBG that is equipped with a wound (elelctromagnetic) pickup. This is because of the difference in the way the different pickups work. A piezo pup works by transforming a actual vibration of the surface to which they are attached into a minute current that is amplified. So the acoustic sound of the vibrating top is picked up directly by the peizo and is then amplified. An electro/magnetic pup works by being "excited" by the changes in the magnetic field caused by the vibrating strings. This excitation produces a minute current that is then amplified. So..... the differences in an electro/magnetic pup equipped guitar is only influenced in minor ways by chamber/hollow/solid body design differences.... This differences have huuuuuuuge implications when the only pup is a piez0....
What does all this mean to a CBG builder? know what sound you are after and design and build your CBG toward that sound. If you don't know, don't worrry about it all... just build, learn and build some more... I have 200 builds under my belt and I'm still exploring possibilites and learning with each build...
hope this helped,

SAM,
so what make a CBG sound different to a "normal" guitar if you make it solid or fully braced and run humbuckers etc? please excuse my ignorance as only new to all this musical qualitys of guitars etc.
Can understand the acoustic of the "box" with a peizo pick up ok. So is it more about the Style for "full electrics set ups"?
Once you commit to such a heavy pup as a humbucker, you effectively kill the acoustic volume and tone of the top, therefore it really doesn't make much difference whether you float the top or make it as a solid body... I like access to the box insides and never glue top and bottom together....
My early CBGs using wound pups were "open tops" I recessed the neck enough to accomodate the thickness of the pup. This required that I add extra thickness to the underside of the neck to strengthen the neck with the recessing is.
I've moved on to "solid body" construction, were the top is essentially the "pick guard" with pups, pots and jack mounted on it. The box is filled with wood with routed recesses for pups, etc. and a pocket for neck attachment...
hope this rambleing helps,,,

You can leave off sound holes, which may cause feedback at higher volumes (at least they do on regular guitars).
