1974 Music Man HD-130 Reverb Black, Very Good, $600.00

This c1974 Music Man HD-130 amp head serial number B000535 is in very good condition. There are some “scuffs and nicks” in the black tolex covering, a little corrosion on the chassis straps, overall nice shape. These amplifiers are becoming harder to find as they have always had and are continuing to develop a following. They are rugged powerful roadworthy units that were the first designs to incorporate a hybrid of tube and solid-state technology.

The preamps used solid state integrated circuits, while the power amps featured a tube driven output stage utilizing 4- EL34s. The preamp in the Music Man amps, unlike the corresponding Fender amps, can really overdrive and this early design uses a 12AX7 inverter tube. Another unusual feature of this amp is the tremolo circuit, in addition to tremolo speed, the “tremolo intensity control provides a double function. At settings from zero to five, modulation varies from zero to 100% respectively. At settings above five, a second modulation pulse is added giving a Doppler effect that simulates a rotating speaker."

The reverb sounds quite good and this is one of the earliest designs to offer both Master Volume and a power reduction switch. These amps are quite loud, work really well with pedals and offer good headroom with bright “highs”, strong “mids” and “lows”, lots of punch!

Music Man amps were Eric Clapton's main amp for years, and Johnny Winter used them to the end.

These are great amps, ad one to your collection!
