Best Custom built analog summing mixers

The Vintage Maker Summing Mixer made my mixes sound “wider” and “deeper”

and dare I say, there was a certain “sweetness” that in-the-box mixing does not give you.

So the colors available though analog summing did shine through in the end (although mine was more of a hybrid mixing process) and if you’ve spent substantial time and effort tweaking your mixes as I have, it might behoove you to visit a studio like Pughouse for what I’d like to call “post-processing” before your down mix. read more

Go with a vintage maker. Great guy with fantastic sounding summing mixers at a very reasonable cost. You can get an many channels and options you want.” Gearslutz

Paul makes some amazing high quality summing mixers,

I’ve owned the Dangerous 2 Buss and the Roll Folcrom

and this easily holds its own with those units. The real deal maker is that you can get a custom built one that suits your exact needs. The international shipping was very fast to the West Coast USA, and the build time was within a week for my specific custom needs.  I’m so glad I came across Paul’s stuff. Definitely a great choice!!

MIXARE IN ANALOGICO DIRETTAMENTE DALLA TUA DAW! l'idea è di controllare i livelli, i pan, eq e mandate effetti del tuo mix con la DAW e mandare 8-16-32-64 o più tracce o sub-mix al sommatore, così da gestire solo la somma nel dominio analogico.
