Just out of curiosity, earlier today I was nerding out with Michael Manring playing and his use of the hyperbass. And that got me thinking, if one would like to take an approach similar to Mike's and install 4 de-tuners on a regular bass, are there any basses on the market that would support this? I know that the headstock needs to have particular dimensions to accomodate 4 de-tuners. I know that for instance a regular Fender headstock would not allow this. Do you have knowledge of any bass that would accomodate this without the need of going to a luthier to build it?
