Check the listing for details. Black Lion Audio Bluey 500 FET Limiting Amplifier. Condition: New. Listed at 699.00 USD. Your Very Own Bluey Experienced recording engineers are familiar with the concept of “happy accidents” — those once-in-a-blue-moon moments that ignite spontaneous magic in your recordings. You can’t plan them — they’re organic, comprised of sheer randomness or even bone-headed mistakes. It’s the guitarist getting caught in the wrong key (“modal jazz!”); the wrong track patched into the sidechain (“Grammy-winning engineering!”); singers riffing when they thought it was just a run-through (“pure poetic brilliance!”). The same audio gods sometimes smile down upon a piece of vintage gear. Through decades of repair and maintenance, some units seem to improve with time.
