These things are highly regarded on HCAF (and elsewhere) and do seem to be increasingly rare. So the price is firm. PM "Elric" on HCAF for questions.
I already have two MP-1's and have pretty much found my sound with those preamps so I am letting the Piranha go to finance a power amp for one of the ADA's. That said, these things do kick ass and if I could justify keeping it while still buying the power amp, I would definitely keep it.
These things really are built like a tank, BTW. I mean it is physically HEAVY for a preamp and the metal housing is super robust.
This particular specimen is in really good cosmetic condition, it only has a very minimal amount of rack rash/scratches, and has been very well treated. It's in great working order and is loaded with a pair of hand selected high gain graded low hour tubes from Doug's Tubes: 1 Tung-Sol Reissue 12AX7 in the V1 slot and 1 Chinese Shuguang 9th Gen tube in the V2 position.
Not pictured but included will be the Power Cord and a double sided laser printed hard copy of the manual (I do not have the original). The manual is also downloadable from Rocktron's site, as well.
