For sale: Shadow Hills Dual Vandergraph. This is a stereo compressor in the API 500 series format. I purchased it used last year and have been using it in a non-smoking, pet-free recording studio. It has not been taken outside the studio. I have confirmed that all functions are working for this sale. There is some wear and tear, and some rust on the screws, but it is still in good working condition. Please note that I have not performed any precise measurements. The only item included is the main unit; there are no other accessories. Please be aware that this item is also listed on other sites, and may be removed from sale without notice. Thank you for your understanding.
