I have one of those Ibanez SR3000e Prestige 4 string basses that come stock with custom Bartolini pickups and Ibanez's 3 band vari mid hi-fi EQ. I really like the bass.....both the look and the feel. However, I'm having a little trouble with the Vari Mid Hi-Fi EQ. I can't seem to tweak it to my liking. It might actually be too much preamp for me. So, I'm thinking of taking a Bartolini NTBT 2 band EQ (HR 4.5 harness) out of one of my other basses and putting it in the Ibanez. I figure the Bart pickups should work well with a Bart preamp. What do you guys think? Should a preamp swap make a difference? Any advice? Thanks!!!
