Retro Instruments STA-Level - Tube Compression Amplifier

Retro Instruments STA-Level - Tube Compression Amplifier

The Retro Instruments Sta-Level is a replica of the radio standard 1956 Gates Sta-Level, which dominated the sound of radio through the 1960’s. The device performs with density and consistency while curtailing many common compressor side effects at up to 40db gain reduction.

The Retro Instruments incarnation contains modern revisions to the classic design. Two Sta-Levels can be paired together for stereo usage, the valves can switched between a single 6386 or a pair of 6BJ6s depending on user preference, side chain operation, XLR input, IEC power input and custom wound transformers.
