Well, i should soon be receiving my warmoth fretless 5-string bass, but haven't yet decided fully on the Pre. I'm thinking of getting bart 59CBJD L1/LN1 pickups. And am less certain, but most frequently settlign on a Bart NTMB preamp. The two things i am uncertain of are, firstly how many knobs to get. I'm leaning towards 5 knobs, voume, blend, and 3 band EQ, but don't know if i will regret having the 5 holes drilled if i decide at a later date to swap out the pre for something will elss knobs. can you fill in the holes? Also, are the EQ frequencies useful on the bart preamps, compared to the nordstrand for instance, the treble is very high (10Khz compared to 4 Khz), and the bass abit lower. I also worry if i will miss having a 500Hz mid frequency for boosting rather than to 250 & 800Hz on the mid selector. Any thoughts/experiecnes welcome. Maybe i'm just thinking to much.
