hi! i just brought a warwick fortress one bass, and i really really like it, can get it out of my hands. this is the only complaint i have. i have also a 77 jazz bass. wich i also like a lot! when i use the bidge pup only, and cut the tone to zero, the jazz gives me that funky sound rich of mids that i use a lot. the warwick has those mids and that growl too, but when i cut the treble in the warwick pre amp, those mods seem to go away with the treble...... so, i wonder what is the frequency that the jazz bass cuts, and which is the one that the warwick cuts..... and also if i can do any mod to change that freq! is there a web site with this technicall info? or someone here can helpo me out? thancks in advance!
