But I really don't like the idea of all the digital encoders and the workflow it all implies. The JVM for instance has 12 different modes, more or less 12 different Marshall classic sounds ... and it is really really easy to use. The VHX seems like it might be a ballache, and you always get at least one level of AD/DA conversion, as I understand it... even when not using any of the built in effects.
I've owned the JVM410.
I get the apprehension about the VHX. Diezel's UI (knob positions - even on their traditional amps) is a bit weird.
FWIW, I don't find the VXH any more difficult to use than the JVM.
To switch channels, you simply push the top control knob. Each push changes the channel (green, yellow, blue, red).
The second control knob: Turn to change Shape parameter or enable Bright switch (Yellow channel), push to change between the four voices (Vintage, Early, Classic, Modern).
The Tone-Stack, Presence/Deep, and Volume knobs all stay consistent (you can see the value of each numerically and graphically).
To enable the Boost, you just push the Volume knob.
I wish the onboard effects could be switched to parallel.
I don't notice any sound degradation.
The transient-response of the amp certainly isn't blurred. It's very tight.
Someone described the VHX as being a bit "stiff" compared to more vintage amps. I'd agree with that.
BAD is sharing tech between the various brands it distributing. IRX, Astro, and VHX all have similar features.
