Dear Folk, I've released the Verb GOLD.
I think that some explanation on how it works could be interesting for all, first there is a very bad picture of its design here

I think that COMB filters and ALL pass Filters tanks are both worth. They do not give the same result.
The GoldVerb do not uses any CombFilters. But AllPass needs to be encapsuled in a Feedback delay network otherwise you loose too much of you original signal dynamics.
The goal of the FDN is to keep the signal and re-inject it as much as possible in order to have the best density.
In the Verb GOld I've used 3 FND in parallel.
- one with 2 delays (use the Del1 & del2 button to play with them)
- one with the Vtube + a Waveshaper (the preset "Distorsion" boots the waveshaper for fun.
- one with several filters (Filter button) and a panning effect.
When I was studying the Lexicon (I've sampled almost all their presets), I've came to thses conclusions :
- they use a panning effect at the end of the chain.
- they use a flanger that they sync with the delay length to obtain this kind of doppler effect.
- they boost the bass and the treble.
- they use a waveshaper on the bass and on the treble to give the bass a "fire burning" like sound and to the treble the smooth that is not naturaly included in the original sound.
Even if I've not the same sound in the Verb Gold (it is not a copy and it was not the idea), the results can be very similar.
The difficulty with a FND is the feedback loop.
To have a very warm sound, you must maximize the feedback and stay at the limit of larsen. That's why each preset must be tunned internaly carefully.
Several other effects must be included in order to create more harmonics and more effects, flanger, and chorus are in play.
Finaly a Reverb is very close to a multi effect included in a feedback loop
