About This Listing

1978 Music Man HD-130 head in very good condition

It features one clean channel with Volume, Bass, Middle and Treble controls and a Bright switch, and a second channel with Volume, Bass, Middle, Treble and Bright switch. Both channels go through a Master Volume and a Deep switch. Extraordinary clean Fender style tones, and stays clean almost all the way to Extra loud.. The amp has a low/high power switch (130/65 watts), which drops the plate voltage on the low power setting so the natural tube distortion happens earlier. Takes pedals gloriously.

The original Schumacher transformer date this amp to 1978 and the serial number is A000173. It’s had all of it’s electrolytic filter caps replaced with F&T Caps as well as all other electrolytic caps replaced with either F&T or Spragues. All transistors were tested and found to be good. A few drifted resistors were replaced. The tube sockets were all cleaned and re-tensioned. All of the pots were de-oxitized and are noise-free. The quad set of ELH84 Electroharmonix driver tubes all test strong and the classic 12AX7 GE splitter/PI tube was tested and is very strong. This is the very desirable 12AX7 driver tube, where later versions were transistorized. The amp can run 6CA7s or KT77(ELH 84) output tubes as well but must be re-biased.
The metal corner caps and hold-down straps show some pitting, tarnishing and scratches. The tolex has some flaws and nicks (see the pictures) but overall in good condition. The from panel is in excellent shape, no scratches with all text legible and all the original knobs in great shape. The back panel is also in great shape with all text legible and no scratches.

This is a great head portable and powerful enough for any gig. This amp has been completely restored and tested, sounds fantastic and will keep rocking for another 40 plus years. Please check out my 5 star reviews here on Reverb from my satisfied customers.
