I recently installed a set of D'Addario Zyex Medium Tension strings (DX610 3/4M) on my Stagg EUB, and what an improvement over the factory strings that had been on it for several years (well .. at least when you play pizzicato). At the next rehearsal with my string band, I used the Stagg rather than my Sam Eastman upright (we had a gig the next day and it was still bagged from our last gig). Despite having the Stagg for several years and using it for many rehearsals, gigs and practice sessions, not once had I bowed it. During the rehearsal, as usual, I applied a lot of Pops Rosin to my bass bow, and when I bowed the bass ..... just a pathetic little squeak came out of the amp (a Markbass Little Mark Tube 800 and Ampeg 1x15 cabinet). The pizzicato volume was fine, but there was no "body" whatsoever to the sound when the bass was bowed. I was expecting to have to turn down the volume on the amp when I bowed the bass, not crank it to 11. Does anyone have any insight on why this might have happened? > The strings were steel and were new > The pizz sound was loud > The 9-volt in the bass was good (I swapped it out to make certain) > The amp settings were not adjusted to a lower volume > The bow was the typical tightness and had plenty of Pop's Rosin (which I reapplied and still got the same results) > D'Addario's web site says the strings "provid(e) a rich, complex tone with power and clarity ... for both pizzicato and bowing."
