I see that a lot of people put flatwounds on these. I've a nylon (nylong covered?) string on mine (was on it when I bought it). I'm looking to use it largely for country/blue grass. I'd love to have as close to a stand up bass sound as possible. Are flatwounds the way to go? If so, what are the recommendations? Since it's a somewhat short scale, I know true short scale strings won't work. I saw that someone uses custom strings. Any help would be appreciated. Thanks.
