Hi guys! I have a Vintage V4 P bass style bass guitar. It has ghs boomers 45-105 and the bass has about 4-5 dead spots. Mostly from fret 1-6. Unfortunatnely on the places which i usually play. I tried compressor,sustainer, capo on the head. But nothing changed. I still clearly hear the dead spots on the guitar played plugged or acousticly. Is there any advice how to remove them? Would changing to Flats help? Another question. Do you guys also hear open strings sound bad and sound much low volume than fretted notes or is it just for me? And if if i play with pick it is worse. Sometimes it is unavoidable to play open notes. For example the E and G string. And what can i do with it? Thanks.
