Sansamp BDDI, good shape with some scratches. Works perfectly. This is an amazing product. It sounds just like their RB-1 rackmount pre-amp. I know because I owned both. You can dial in most any tone you want. It does a great job for that "SVT" tone. My only reason to sell is that I just don't use it any more. I am trying to simplify may life these days. My Ampeg SVP pre-amp/power amp rig handles all my large gigs and the Mesa Walkabout does the rest. I will also include a downloaded copy of the owners manual. Asking $120.00 shipped in conus. I am having trouble getting the pics loaded in the forum so email for pics: firstname.lastname@example.org Paypal preferred.
