Shift Line Twin #158154 by LongStrangeJam Thu Aug 31, 2017 7:48 am It's a blackface tube twin preamp. Looks pretty good, not as good as the SMS though. Was wondering if anyone has tried it? Looks small. Thanks http://shift-line.com/card.php?device=75 "Rock the boat, skin the goat!" Username LongStrangeJam Rank Rosebud Posts 44 Joined Tue Jun 30, 2015 9:58 am Location Front row.
