I'm still working on my finger technique but sometimes I hit the low E string so hard that it rattles against the pickup making a nasty pop sound. Also sometimes I accidentally press my thumb against that E string to the point that it hits the pickup. I'm wondering if this is purely my poor technique or is it something to do with my bass. I have an Ibanez SoundGear SR370E. Do I need a $1,000 Fender instead?
