This is the best Synergy module yet!!! JVM level gain and then some!! I have to make myself pull out my other modules and use them lol this one gets more use than any of the other others. I have actual Marshall heads Jcm 800, 2555x, JCM 2000, etc so I can compare this to the real Marshall stuff. It is spot on. I use an Origin 50 head to run my Syn-1 dock into because the origin has post loop master volume & presence knobs that are fully functional when slaving the Synergy into and it’s fantastic because that makes balancing levels easier. The JVM module just get one and thank me later
