What is the difference between a Rams Head and a Violet Rams Head?
This has many answers and the generally agreed on answer is that the violet is a little brighter.
Much circuit difference is lost in the sweep of the pots where it's impossible to set two same pcb same parts specs pedals for the exact same sound because pots vary in full resistance as well as along the sweep.
I eliminate those variables the way I use muffs though, because I want full brightness.
So I start with sustain and tone knobs full up, then adjust volume for the same level.
It's important to first understand that the sustain knob is not like a distortion knob and doesn't get clearer sounds as you turn it down.
What turning the sustain knob down does is cut treble and boost bass.
To my ear turning down the sustain knob also delivers more scooped tone by boosting bass, and the least scoop is found with sustain up all the way. cutting the sustain just a little cuts some treble without bringing bass into dominance, but also there are mids in that treble content, like the mids on a Marshall mids knob. The extra mids of a Russian is more low mids.
Less treble and more bass actually sounds more distorted and less clear, where we generally expect less distorted and more clear when we turn down the gain knob on a dirt pedal.
So I have two Rams and three Violet Rams, and they all sound a little different.
I actually find the Vick Violet Ram is not as bright and clear as the two Chicago Stompworks Violet Rams, and the Vick is also more grainy where what I love about the Violet and a good basic Rams head is the ability to get totally pure grit free high notes.
The Chicago violet is really hard to tell from the Chicago Ram, I can get as much variation from pick attack as I can assign to circuit difference, and I run them through a dual loop pedal so one stomp switches between the two seamlessly.
Even switching in a held sustained note they are very close, but setting all knobs in the middle of their sweeps you simply cannot fairly state that one sounds brighter and the other sounds darker.
Even two identical muffs on a board can deliver two distinctly different sounds and it's IMO worth having several!
The Large Beaver Ram is a little less bright than the two Chicago violets and the Chicago Ram, but more like the Vick violet in brightness while a touch more grainy. This with the Vick and the Beaver set to stock mids.
I also have two Civil War era Russian circuits from SUF and Big knob, plus the SUF is the Civil Unrest with the added mids knob.
Interestingly the SUF is a little more grainy which seems to come with higher pricing.
I love the less grainy pure sounds more than the grainy sounding muffs, and we can easily add grain with pick attack but cannot remove the basic grain a given build has with softest pick attack.
The mids knob on the SUF is a masterful bit of circuitry and can even go past the scoop of the stock circuit, but that means you have to bring it up a little to get the stock amount of scoop.
All these Russians are a bit more grainy than any of the Rams.
Noise is a big issue with muffs and each sample has a slightly different noise level, which can be reduced by lowering the sustain knob which also cuts treble where some of that noise is generated.
