I'm trying to see how many people have changed out the stock pickup's on an Essex bass. I have one of the basic P-Bass Essex's and I am getting a really full sound with any note played on the E string...however any note played on the A, D, or G string is lacking volume/tone in a huge way. I have adjusted the compression on my rig in every way possible but nothing helps. I suspect it's got to be the pickup's. For the total price I paid for this bass I assume the pickup's probably need to be changed to correct this and I was wondering what pickup's would give me a really full sound on all strings. It's a standard passive P-Bass pickup.
