1981 Music Man HD-150 Reverb Amp Head Black

Offered for sale:

Used 1981 Music Man HD-150 Reverb Amp head with reverb serial number B013079.

This amp head is in very good condition, fully functional, cosmetically showing very slight tarnishing of the brightwork and the grille material sheds slightly when caressed. This is a very clean and intact HD-150 Reverb.

The HD-150 Reverb has 4 6L6GC power tubes, 150 watts RMS and two channels. Features include a two-band EQ on the first channel, a three-band EQ on the second channel as well as Bright and Deep switches, reverb and a Master Volume control. As with all Music Man amps it also has a Hi/Low power switch.

Additionally, exclusive to Music Man, the second channel features intensity and speed controls for - ready for this? - the ‘Phasor” circuit (the forerunner to the flanger and chorus). At the time Music Man thought the phase shifter would replace the decades old tremolo for the modulation effect. It really makes this amp stand out.

The push/pull SPEED knob/switch works in tandem with the adjacent INTENSITY knob.

By pulling the knob, you turn off the sweep and allow the phase point to be set manually by the knob. It is a little like setting a Wah-Wah at one point and leaving it there rather than working the pedal. This gives you and interesting tone variant you can control that will sound different than standard tone controls because it is phase dependent!

This design was considerably ahead of its time, a true hybrid, featuring a well-designed solid-state preamp circuit for clarity and headroom, and the output stage is where so much of the real tube-tone comes to life. The HD-150 runs its power tubes at very high voltages, upward of 700 volts DC on the plates. The half-power switch reduces output not by switching out two of the four tubes, but by reducing the B+ to drop the tubes’ efficiency.

The Music Man HD series was a favorite with luminaries like Eric Clapton and Johnny Winter. Johnny played live with his Music Mans right up to the end. Little known fact: It works amazingly well with Metal.

This is the most powerful amp Music Man ever produced. A great sounding workhorse and powerhouse in one!
