Hi there,
I have a Salvation Mods Mashall+ module in pristine condition.
I also have a mint Synergy BE module (dual Channel) but and its not that heavy but it has that Friedman L.A sound, more of JCM800 style and not so much plexi.
Lastly, i have the Synergy BMAN, not a plexi but Marshall started out their JTM amps based on the Fender Baseman so it has that old school JTM Marshall sound and this BMAN gets heavy as well for an overdrive preamp. Dual channels and each channel is voiced differently with EQ switches.
All modules are in like-new condition.
You can contact Matt Fig and ask about my reputation on this forum, i go back 7 years now.
Let me know if anything interests you.
