PreSonus DP Blue Tube Microphone Instrument Preamp

Up for auction is a PreSonus DP BlueTube Microphone/Instrument Preamp,
Which is in Excellent Condition.
Selling for my son who is very meticulous about his equipment.
He is selling only because he upgraded to an Art tube preamp.
Complete with original box, manual, registration card and power supply.
