A classic piece of late-1970s American musical engineering, this Vintage Unicord Stage 720 (Model S720L) 4x10 Guitar Combo Amp comes straight from the corporate lineage of Univox. Manufactured for Unicord Incorporated in Westbury, New York—the parent company responsible for Univox guitars and legendary amplifiers—the Stage series was engineered alongside Univox products to provide professional gigging musicians with road-tough, high-headroom performance.
The amplifier features a versatile dual-channel preamp layout. Three front-panel inputs offer dedicated access to Channel 1, Channel 2, or an integrated 1+2 blend input that couples both channels simultaneously. Channel 1 delivers grit and bite via its onboard Clipping overdrive circuit and a Pull-Bright volume boost. Channel 2 is voiced for articulate clean articulation with dedicated Volume, Bass, Mid, and Treble EQ controls, all flowing through a lush internal spring reverb circuit and Master Volume.
Powered by a discrete analog solid-state output section, this combo pushes through a factory-original 4x10 open-back cabinet configuration. The four 10" speakers deliver punchy low-end firmness, quick transient response, and broad stage dispersion that easily cuts through a live band mix. The rear control panel provides connections for a 1/4" Line Out, footswitch jacks for both Reverb and Clipping engagement, and an integrated chassis fuse block. Showing honest vintage cosmetic character, the cabinet, tolex covering, and woven grille cloth remain structurally solid and ready for the stage, rehearsal space, or studio.
