I'm thinking about changing out the pre on my Ibanez SR 1805 to a Nordstrand 3 band pre. It has the Nordstrand big singles and has a good sound but I feel like it could be better. What is everyones opinion on this and does anyone know anything about the stock pre's on the Ibanez Premium basses? Would I be crazy to switch out and would it make much of a diffrence?
