Original vintage Sunn Concert Bass amplifier head from the early-mid 1970s. This amp was owned by my grandfather, a bass player, and has remained in the family since presumably new. It has been in long-term storage.
Made in the USA by Sunn Musical Equipment Co., the Concert Bass is known for its massive clean headroom, reliability, and classic Sunn tone. Features include bright/normal inputs, treble boost switch, full EQ section, preamp out / power amp in, and original Sunn branding throughout.
The amplifier shows honest vintage wear consistent with age and use, including cosmetic wear, oxidation, and dust. It has not been tested, as I wanted to leave it exactly as it was found and avoid any risk of damage after long-term storage. The amp has not been modified or altered to my knowledge.
Includes the original Sunn dust cover, which is rarely found.
This amp is being sold as-is / untested and would be an excellent candidate for servicing, restoration, studio or stage use, or for collectors seeking an original Sunn bass head with provenance.
