The ever-popular question - what E and A goes well with guts? My current situation - a bluegrass / country / occasional slap player - no arco. Have a '38 American Standard with EP Slaps with gut. The tone, volume, and balance works well for that bass. Also have a carved roundback that only sees fair weather and indoor situations. Currently has EP Slap gut set on it as well, which hasn't been a bad way to go, but willing to take a leap if the reward is worth the investment. Love the old school gut sound - Jr. Huskey, Bob Moore, Roy Jr., Dennis Crouch. Yes, technique has about another 40 years or so to go... Otherwise, considering Oliv, Chorda, Eudoxa, etc. with Gamut heavy Lyon G and medium Pistoy D. It's a better bass than I deserve, and want to make the most of it.
