Rockabilly slap - open strings ringing

[SICbass]

Hi All,

 

I am one of those electric bass players, who occasionally plays some rock'n'roll on upright bass. VERY occasionally, I need to slap a few bars.

When doing this, (eg. with a single slap) I struggle keeping the E and A strings from sympathetically resonanting when slapping the D and G strings - particularly when amplified.

I am playing the D and G strings cleanly, but can't mute with the right hand, as I'm raising it from the fingerboard between slaps.

 

Any experienced "slappers" out there who can offer some tips?

 

Cheers,

Paul

What? No one can offer me any advice?
