I have really enjoyed testing this new effect, I am fascinated with the modeling tech for this spring reverb effect, and I am appreciative of the explanations about how it works behind the face plate.
This effect does seem particularly prone to sounding muddy and congested, and it can seem like a struggle to get a rich effect while clearing out the lower mid range. Reducing the decay and density settings can be helpful. I have noticed that the low mid distortion seems internal to the dsp. In other words, even when the input and output levels are conservative, it seems easy to create a scenario where the intermediary stages are over driven, distorting, and creating a woofy, congested, muddy tonality that is unfamiliar, and perhaps undesirable.
This impression is promoted by the way the mix knob works to lower the dry signal while you add the wet. With many reverb effects you can stack on the wet while maintaining the brightness of the dry signal. With Twangstrom's Mix function, as you increase the wet you are rapidly decreasing the upper mid and high range output.
It seems, to me, that using this topology to achieve the 100% Wet capability, that enables Twangstrom to serve as a bus effect, diminishes the best use of this dsp as an instrument or track effect. Spring reverb is a very popular instrument or track effect. This is how I have been testing it, because this is how I intend to use it, but with the current Mix configuration it seems as if I will want to set up a parallel 100% wet signal so that I may adjust the level of effect without deprecating the bright dry signal. It seems unfortunate, because each instance of spring reverb is likely to be instrument specific, and unlikely to be shared.
It is admittedly possible to use the current Mix function to find a balance point that is suitable for any particular type of signal, but it requires very specific placement on the Mix knob's arc. IMHO If the wet was added to the dry signal, while the dry signal remained constant, the function would seem a lot more forgiving and there would seem to be a wider range of suitable sweet spot adjustment.
I have enjoyed the beta so much that I have crafted a custom skin for my personal use:

Thank you.
