The Abstrakt Avalon was built to perfectly replicate a vintage Roland TB-303, then go further — an extra mod envelope, deeper controls, real metal build quality. It was also rare, expensive on the secondary market, and hard to find; some people waited half a decade for delivery. This recreation gives you everything the hardware did, then keeps going: more programming modes, tweakable slide/glide and resonance, Devil Fish mods, every filter cartridge (even your own), four colored skins, and the should-be-patentable EZ buttons. db-cell technology underneath adds the non-repeating analog noise that makes vintage circuits sound the way they do.
