About This Video

In this video I put the Synergy VH4 module up against the real Diezel VH4 and tried to answer the big question: can the module actually hang with the real amp, or is it just “VH4-ish”? The cool part is Peter Diezel designed the module, so it’s not some random clone attempt—his fingerprints are all over it, and the voicing is very accurate. I ran both amps into my KHE amp switcher so I could flip back and forth fast, and I used my Tokai with Sheptone BK PAFs straight in—no boost—into a Splawn cab with a V30, mic’d with an SM57 and an MD421. I dialed the real VH4 the way I like it, then matched the Synergy to that (not the other way around). The takeaway is pretty simple: the Synergy nails a lot of the VH4 voice, especially channel 3, and for the price gap it’s a hard deal to pass up if that’s what you’re chasing. But the real VH4 is capable of a huge extended low end and a strong top end that stays smooth—this massive spectrum and feel is something the EL84-based Syn20 IR power section just can’t fully reproduce. In a full mix, though, that “difference” can matter less than you’d think.
