Test of Prototype.

With SS

& Tube preamps.

Because they have the same board connectors pinouts, swapping was very easy.
Controls settings are the same for different preamps while recording.
Fet_vs_Tube
Archive contains mix & only guitar tracks.
Legend:
SX_Y
X - track number
Y - preamp number
SX_YG - only guitar without mix.
Try to estimate who is who.

Amazing stuff! My guess is preamp1 are the fets and preamp2 are the tubes.

That is awesome!  Are you going to be selling these online?  If so, how much?
