I have an idea for a fretless bass that will have piezo and magnetic pickups. I picture a two piece bass bridge, with a string anchor part, like a Warwick: ....going over some sort of saddles like this with the piezos mounted in it: Under the bridge would be hollow, with the hope that would create some nice tones. I'm thinking a mahogany body with possibly a spruce top. Any idea where I could get that anchor part like the Warwick? Or a wood saddle with piezo's already mounted in it?
