Hello. I bought an ESP Ltd. BE-5 about seven years ago, which has passive pickups and a 3-band eq active onboard preamp. Shortly after I bought it, I put EMG passive soapbars in it and I honestly did not notice a huge difference. The bass sounds good but it is a little bit quieter and less bassy than my friends' basses (unless I boost the bass). I'm thinking about switching the stock preamp with the EMG BQS System. Do you think I should expect to hear an improvement in overall tone quality compared to the stock preamp, or would I mostly just be paying for the concentric stacked sweepable mid? Thanks.
