Pirastro Evah Pirazzi Slap Strings Set

The bass strings sound great and they play fantastic at first but they deaden off really quickly when slapping and fraying is a big issue with the D and G being only gut.
If you?re playing rockabilly which these strings are advertised as being for, I would advise against them if you play a lot of live gigs as they need frequent tuning but they?re ok for recording if you can afford to keep them just for that purpose as they?re quite expensive.
