Ampeg Mercury Model M-12 1×12 15W Tube Combo c.1957


1 in stock


For sale we have a 1957 Ampeg Mercury Model M-12 1×12 15W Tube Combo in very good condition. This is an early-production, all-American amp with outrageously detailed tone and elegant simplicity. Originally designed as an accordian and/or guitar amp with a 6v6 power tube section, 6SL7 preamp tube section and 15W of output. Two channels, each with volume and tone controls. Channel 1 is a bit darker and warmer with a more reserved gain sweep, probably intended for guitar. Channel 2 was intended as a mic/accordian input and has a nicer breakup when pushed (very tweed Deluxe-esque). Loaded with the original Jensen Concert DP Alnico 5/ P12R 12″ speaker in excellent shape – nicely broken in but not flubby. Speed and Intensity control for the built-in tremolo, which is incredible. Original wooden doorstop footswitch controls on/off for the trem.

This amp has been serviced by our master tech and is sounding excellent. New three-prong power cable, new Mojo Dijon caps, replacement handle, perhaps an unoriginal logo on the control plate?. Basic wear and tear in the thin tolex covering, otherwise very fresh condition for its age!
