I have a Sterling by Musicman Ray34ca (an AWESOME bass, by the way) that I switched out pups for a Nordstrand MM4.2. I love All of the Aguilar tone that I've heard (TH500 through some aggies) and want to capture some of that. I bought this preamp to swap the stock with. Something I'm looking forward to is having stacked High/Low and a Mid with a push/pull frequency selector. I play through a Genz Benz GBE 1200 and an Aguilar GS 412 playing mostly funk rock type stuff. Think this is a good buy? I have never switched an onboard preamp before, and I'm a little nervous about it. I have a friend who does decent soldering jobs, but I'm still scared to mess up my baby. Any advice from those who have swabbed OBPs?
