The main sound determining elements / specials of the Mini are the 24db transistor ladder filter and the Moog Saw waveform - beside the side effects of all other components like the VCA etc.
You can obtain 3 band parametric equalizers for much less money. I looked ad the Moog 3 band equalizer prices / offers and the Moog 3 band equalizer schematics. Totally overpriced. And if you want the Minimoog sound buy a ladder filter clone.
I have a 3 band moog eq ( and many other eqâs) and i have to disagree with the last post . The moog eq is surely dfferent from he eqâs i use : t very well keeps the bass component, never thins out the sound and has when desired a nice drive/ little overdrive possibitiy . I use it with a t3 pedal and it gives me a whole pallete of soundpssiities no other eq could give . ( neither software eqâs) . So is it worth the nowadays marketprice : yes . Same btw for the other 19â vintage moog effects Like the graphic eq and the 12 band phaser, very good material that cannot be replaced as good by things with partly the same name machines when you use your ears.
The three band eq is a one of a kind eq in the field , makes my t3 rock , the prices are firm but fair .
Btw he sub37 is a nice but bit polished sound. If you want more roughness but canât pay for a vintage minimoog iâd suggest to try the grandmother or matriarch instead , i think soundwise itâll come much closer to your wish.
