    Hi everybody,

    I’m looking to do a fun project and try to create a hybrid between a bass and guitar by using a Gretsch G2220 Electromatic Junior Jet II (red finish) and modifying it.

    First, I am deciding between using light-gauge short scale strings or piccolo strings. Since piccolo strings are an octave higher, they would do the job well, but D’Addario only makes a set for long-scale basses. Would these long-scale strings sound good (or even work well) on a short-scale bass without messing up the neck too much?

    Second, I was looking to coil-split it, so I could have the “Les Paul vs. Strat” effect. I’ve heard that the default Gretsch mini humbuckers aren’t too good, so I was thinking of upgrading them to humbuckers that could fit in the bass well without much drilling and be coil-split. Is this at all possible, or are there no pickups that would fit into the mini humbucker cavity? Also, any recommendations on good cheap (<$150) pickups would be greatly appreciated.

    Finally, with the lighter sound/strings, I thought about adding a Bigsby B5 to the bass. I know I’d have to replace the normal Fender-style bridge for a rolling one or a tune-o-matic one, but would a Bigsby be able to handle this kind of general setup since I’m not using super-heavy strings?

    Thanks so much for the help!

  3. Not sure where to check the wound length of guitar strings, maybe the manufacturer web site but I’d bet there are at least some guitar strings long enough to work on a short scale bass as piccolo strings.

    If you do go with a tune-o-matic type bridge you will need to shim the neck to get a good string height. If you look around, Bigsby has a shim for Telecasters. Don’t know if it would fit the Gretsch but it will give you an idea and they’re not too difficult to make. I’ve made a couple of full length shims like that.

    The only difference between piccolo bass strings and guitar strings is the length.

    Are you converting the Gretsh from six strings to four?

    If that’s the worst I need to do to modify the guitar, then that’s not bad at all! They’re probably super cheap to make too!

    The Gretsch is already only 4 strings, so that’s why I was looking at piccolo strings vs. guitar strings. Are piccolo strings thicker than guitar strings?

    Oh, ok, I thought you were converting a guitar, not making a bass into a piccolo bass. Got it.

    They're both available in different gauges. What gauge you use depends on the feel you want.
    Generally you start with about half the gauge of standard tuned strings for an octave up at the same tension.
    If guitar strings fit in terms of length there's no reason not to use them.
