Presonus Eureka pre-amp / eq / compressor. It has been sitting for a couple of years at least with almost no use. I tested prior to boxing up to prepare for shipping and everything is fine with the unit. Since i have had it i had used to very little. I just don't have enough time / skill to justify keeping it. No smoking around the unit since i've had it. Please note this does not come with the adat digital option. You may still be able to purchase this add on.
