1956 GATES STA-LEVEL # 4 Compressor AUDIO TEST # 3 Ashley Pearl 

1956 Gates Sta-Level compressor. Here's a video of my daughter singing one of her original songs on the piano and I'm playing the synth. The music was not mastered down with a compressor, so this test is to see how unprocessed audio works with the Sta-Level This Gates is one of the best examples found to date, super clean and well cared for. Look for it on Ebay soon!
