I have a set of MXY56, 5 string Pickups and Onboard Preamp
Controls vol, pan, bass, treble
 
$1100 New, these are in good shape & I would let them go for $450
 
I listed these before, but I recently sent them to Alembic who replaced one pickup that had a hairline crack on the screw mount (Now replaced) & the entire preamp was gone over to make sure it is in perfect working order. They even included a 1/4 input jack that was missing. Now it is ready to go!

Couple of pics for those who asked  

SOLD
 
Thanks
