Curious, I just purchased a Rickenbacker 4001 V63, immediately slapped on a set of Rotosound Round Wound 66DL ranging from 45 to 105 (big fan of Chris Squire) and wow the A, D, G sound phenomenal and the bass plays beautifully, but the E is just dead. I was like what the **** so I just bought a set of DL Hi-Lights that I will try tonight. But has anyone run into trouble with the bass itself giving this result versus the string on a Rickenbacker? I want all the strings to be alive with ringing sustain, why else would you buy a Rick. Curious to know what others think and if they run into this even after trying different strings what do you do to the bass to get rid of the "DEAD ZONE"?
