Re: Ultra Phonix mod for Bandmaster

Taylor, Can you verify that the gain voicing is different from "La Tostada" ? I've done the La Tostada a few times. Great rock tones from whats essentially a JCM800 based preamp. Sent from my moto g(6) using Tapatalk I don’t have any info on that preamp. I’d like to know the Mega Plex, Winterland, ...

Re: Did I get this right, I wonder?
