Demeter brought the new VTBP-M-800D head to NAMM. Based on the VTBP-201 preamp used by bass legend Lee Sklar for many, many years, the 800D uses a 280V power supply, an 800-watt, class D amp, and full-voiced preamp with input mode switch, bass and presence voicing toggles, DI and line outputs, and two Speakon speaker jacks. All in a 10.5-pound head with options starting at $1,359.
