AMSynths AM1035 Triple Modulator
22 Apr 2024 AMSynths
AMSynths launch the first of ten modules that recreate the "lost modules of the ARP 2500". Re-imagined 50+ years after Tonus created prototypes and ideas that take the 2500 into new sonic territory. The AM1035 is a Triple Modulator with three channels of warm transistor quadrant modulators. Each channel can be set up as a ring modulator, a mixer or a VCA. An incredibly versatile module that creates many different sounds.
