This is an Altec 1591A preamp compressor This preamp is in excellent condition. It's great with dynamic and ribbon microphones. This is one of two 1591a preamps for sale. Both of these have been recapped with carbon capacitors to keep that vintage sound.
The 1588b has also been recapped and sounds very clear with a lot of saturation. This microphone is amazing on acoustic guitar, strings and other acoustic instruments. Depending on the microphone you will want to use an attenuator with any really loud instruments such as drums or electric guitar. But this preamp sounds really great on all of the above.
