2 ART Tube MP Project Series USBs. One of them has an issue with the power supply, but you may have to give it a wiggle for it to pass signal. The signal may be a little crunchy at times due to the damaged power supply. The other preamp will power on, but unfortunately not pass signal. Good for parts.
The Tube MP is the world's most popular external tube microphone preamp. Whether you're working with a digital, computer or analog recording system, the Tube MP's TEC Award-nominated design will allow you to obtain professional recording studio results at a fraction of the cost of comparable equipment.
