At rehearsal I noticed that a borrowed P bass I was playing wasn't cutting through at the low E and F. I wouldn't call it a dead spot as the note is definitely there and is "big" but it's lacking definition. The other notes higher on the string are fine so I don't think its a string issue. It's a great bass otherwise so I'm not sure what's going on with it. I have P basses where this isn't an issue but have run into this on other P basses I've encountered. It's the opposite of what I usually hear from a Jazz bass where the low E is very prominent and volume tends to fall off higher up. I'm wondering if this is something inherent in the P pickup design or pickup placement or the wood. Is there a fix for it?
