I plugged it in and it works.  I am not sure of any technical readings but looks to be complete, original, unmodified, very lightly used and well cared for condition. 

Box has quite a bit of wear in comparison.

Please ask questions and make offers.

The Vintage DeArmond Rhythm Chief Jazz Pickup is a classic piece of musical equipment known for its superior sound quality and durability. Made in the United States by the reputable brand DeArmond.  This pickup is a sought-after choice for musicians looking to elevate their sound with a touch of nostalgia and authenticity.

Not really sure of the value here. Basing it on what I could find. Couldn’t find one in better condition either. Any info is welcomed. Thanks!
