I really like the Epiphone Jack Cassady and the Yamaha BEX basses. I however find faults in both especially the price. I have seen similar modifications before as far as a person taking a 6 string and fitting a bass neck with a bass bridge to create a custom bass. Would this be possible with semi hollow guitar like the yamaha aex? I'd most likely use yamaha bass neck (or maybe fender) and whatever bridge that will work. Are there kits available to build a hollow body that I could fit a bass neck and bridge to? Any suggestions or web site referals are welcome.
