About a week ago, I sent my MIJ P-Bass to the local bass shop to be set up, and I requested that a set of DR Lo Riders be put on. When the bass came out of the shop, the strings sounded really awesome, I could hear the brightness and the 'zing' coming out with every slap or play, i was impressed. One of the reasons I chose DR was due to many claims by other players that they last way longer than other strings. After a week of conservative playing which ended with a gig with loud music (where you don't hear or feel the 'zing'), the strings sound pretty dead to me already. It was very frustrating, there were 2 possibilities to this: 1) the guys at the shop could've put on some crap/cheap strings that don't last at all. could anyone describe the external features of DR Lo Riders to identify them? 2) 'lasting long' as described on the DR website doesn't mean keeping the 'zing' brightness new strings have. maybe it means not breaking? Plz help me out!!!
