I have a mint condition Synergy SYN-2 rack mount preamp with original box and paper work. Works as it should with no issues. There is plenty of information on the internet about this preamp. I will add pictures tonight when I get home.
$650.00
I also have two modules for sale that are mint condition with original boxes and paper work.
Fortin Killer Kali - $350.00 (Modern High Gain)
Synergy DRECT Preamp Module - $350.00 (based on a Mesa Boogie Dual Rectifier)
If you want the SYN2 preamp with both modules I will sell for $1,200.00 for a package.
