The Little Mark Tube gives the warmth and richness of a tube preamp, or the clean attack of a solid state preamp… or a mix of both! On the front panel there are also two inputs with separate gain controls: one 1/4” jack, and one combo jack that accepts either a XLR or 1/4” cable. Additional features include switchable 48V phantom power for the XLR input, solid-state/tube mix control, four bands of equalization, VLE and VPF filters, line out level control, pre-post EQ switch for the XLR out (on rear panel), and mute control (push-pull on the master knob).
