BLUEY 500 compressor with 5 knobs and a VU meter. - Model Name: BLUEY 500 - Meter Type: VU meter - Number of Adjustment Knobs: 5 knobs - Ratio Settings: Up to 20:1 - Bypass Function: With bypass switch Thank you for viewing. Black Lion Audio Bluey 500 This is a bluey 1176 lunchbox (API500) module! I am selling it to free up a slot. Operation confirmed! Of course, it's great for vocal recording, but the attack is more delicate than a full-size 1176 model, so it can also be used in an opto-like way! Complete with box, thank you very much.
