I used to have one just like yours and the stock pickups were very weak... They were marked 'Jackson', not clear form the pics if yours is too. I'm not surprised the QP is overpowering it!

Interestingly, I've recently snagged a 575 (may well be my actual bass that I bought new in the 80's) and I was shocked when I compared the output to my Warwicks. I suppose it shouldn't be such a shock and it's like comparing apples and oranges!
I'm not going to change the electronics, I'll just need to get used to boosting the amp input.
