VINTAGE 1950'S GERMAN MADE HOPF  GUITAR PICKUP ASSEMBLY, RARE and WORKING and it looks like THIS RARE PICKUP ASSEMBLY IS MADE TO ADD ON YOUR VINTAGE ARCH-TOP  or HOLLOW BODY ACOUSTIC GUITAR !!!!!!!!!!I have listened to this pickup arrangement  on a practice amp and it sounds good using a finger nail across the front of the pickup , THE VOLUME CONTROL WORKS , THE SWITCH THAT CONTROLS one or TWO PICKUPS WORKS, AND THE THIRD SWITCH WORKS AS A TONE CONTROL . IT IS IN GOOD CONDITION , JUST A LITTLE DIRTY , I DON'T KNOW WHAT GUITAR IT IS FROM , AND COULD NOT FIND ANOTHER ON LINE ANYWHERE . there is a 1/4 inch  PHONO JACK IN THE UNIT TO CONNECT TO THE AMP , SEE THE PICTURES .THIS COULD GO WITH YOUR OTHER VINTAGE GUITAR  EQUIPMENT . Shipping in the states will be FREE, including insurance, other locations will be extra. I WILL SHIP WORLDWIDE and CHECKS are OK ,Local pickup is always preferred Any questions, please contact audion at roadrunner.com *******************************************good_luck******************************************
