A few days ago I bought a warwick corvette std. 5-string. The B-string is tight, that's a good thing. But the rest of the strings(E,A,D,G) are tight also, but they are too tight to decently make bend down's or vibratos with. The bass I had before this one was a Fender jazz(4-string) with the same string setup(exept for the G) But the Fender also had a floppy B-string and was well suited to make bend downs & vibratos with. The Warwick came with warwick black label(45-135) And I changed the A-D-G with rotosounds swingbass, 40-100's (3 strings) in order to loosen up the strings.. It helped a bit but not enough, what should I do?
