Springs features emulations from 8 types of spring reverbs...
We have used a combination of convolution and modelling..
I purchased it yesterday, sounds great!
Could you make it clear please: is it IRs from hardware or emulation algorithms?

I'm curious about how the mix of convolution and modeling works too.

The core is convolution, so we have captured clean IRs of each reverb (long sweep, denoised, deconvolved). Spring reverbs are, in theory, linear systems, that's why convolution works really well. In reality, some non-linearities are present, and that's where the algorithmic part kicks in (in HQ mode should be more evident).
Also, the input and drive stage change according to the selected spring reverb to match the right behavior. Some are cleaner, some are very dirty, and you can hear the differences if you push the input and drive.

Love the deep but relaxing vibe of the plugin, very musical with the right features.

Thank you! I'll think about it. Usually in hardware spring reverbs, the "time" or "decay" control is just an input/output volume control. Using the 'short' setting and lowering either the Input or the Wet signal might work for your needs.
First of all: a fantastic sounding plug in from Audiothing again! I just bought a license and directly wished a "Decay" knob would be there. Maybe it could be alternatively to the two settings - switchable. Some time ago I sampled a British Spring Reverb myself and used the IR several times in productions. Within my IR plug ins and in my convolution hardware (SREV1) I really enjoy and use the decay parameter a lot. Please implement a decay knob, even if it is not nice sounding for automations. Mostly I use static settings.

Spring reverbs do not have a decay setting. they just naturally decay and that's what you get. To try and emulate an accurate spring reverb means no decay settings. It's actually part of the beautiful sound of a spring reverb. If you absolutely need a decay parameter, then a spring reverb may not be the best tool for the job. It's not even a matter of diverging from the emulation - it's just not how spring reverbs work. I can't fathom how a decay parameter would be implemented on a spring reverb... :shrug: :phones:

A few hardware springs had decay time, like the AKG B20. There was an R20 remote that controlled decay time. Not sure how it worked, whether it was changing spring tension, length, or more likely, just dampening the spring, but some units pulled it off. Here's a tiny bit of info:

You can see it in the expired Reverb listing:

But yes, definitely the exception versus the rule.

This paternalism is awful - who do you think you're talking to?
And I made clear that it can be an option - as "faithful" is not always my thing but flexibility. I like spring reverb IRs, sampled them for myself and tweaked the decay to my liking. Now what? Better get the Authentic Spring Reverb Police ...

The B20 is a beast, I hope I can get my hands on one of them... :)
Anyway, this is from the manual (http://lcweb2.loc.gov/master/mbrs/recor ... 20Unit.pdf):
The spring is adjusted to the required output decay time by means of mechanical
damping. [...] additional dampers are inserted along the coil spring. Their primary effect is to influence low frequencies under 1 kHz, making it possible to
obtain the desired output reverberation frequency response, whose decay time is
6 seconds at 100 Hz, 4.5 seconds at 500 Hz and 2 seconds at 5 kHz. The damper
consists of a small disk mounted on an axle. [...]
So, a very complex system which basically uses dampers to obtain a shorter decay. Frequency response will be quite different I guess.

Anyway, I kept thinking about it, as many already requested a proper decay control. I think I can probably add an "edit" panel where you can fade/trim the IR to the desired decay time. It won't be an automatable parameter for obvious reasons, but it might please those users who really need to fine-tune the decay. I'll see what I can do and if it doesn't alter too much the original idea of the plugin of course.

UAD apparently has already done the AKG BX20:

Mix with the only licensed and endorsed AKG Acoustics BX 20 reverb plug-in
Not sure what this exactly means though. I assume you can still make a spring reverb model that's inspired by the original BX20.

If you use Nebula, Cupwise has the BX20 sampled in really nice package for $29! http://www.cupwise.com/fx/shop/cx20-spr ... 8d115eb4b3

As it [partially] uses IRs, would there be any way of ripping the code from the 'Pitch' module from your fantastic Fog Convolver plugin ?
