~1980 Sunn Beta Lead Black

Offered for sale:

Used c1980 Sunn Beta Lead amp head serial number A22384.

This head is in very good condition, fully functional. Cosmetically there are a few scratches on the front panel and one of the reverb controls has a broken shaft, but it still turns and functions.

Sunn Amplifiers made in the U.S.A., have been long associated with loud rock genres going back to Mountain and early Jeff Beck. More recently with punk, heavy metal, and doom metal and have been associated with such well-known musicians like Kurt Cobain of Nirvana and Buzz Osborne of the Melvins.

The Beta series utilized many advancements in solid state technology in 1979. Noted on the front of the amp is the label “DIGITAL C-MOS TECHNOLOGY”. C-MOS technology plays a large part in the overall sound of the Beta. C-MOS chips are constructed from a combination of MOSFETs to create logic gates, when they distort, they provide soft clipping, much like in tube amps. They can be found in many great pedals, including the Way Huge Red Llama and the Electro-Harmonix Hot Tubes Overdrive. The EQ in the Beta is also somewhat unusual, although it appears fairly normal, a 3 band Bass-Mid-Treble EQ. However, each control is actually an active boost control (centered at 20-400 Hz, 400-1400 Hz and 1400-20,000 Hz respectively) that goes from “Off” (no boost) to roughly 30 dB of boost. Add this EQ to a very powerful 100W solid state power amp and you get the aggressive and powerful sound of the Beta.

This is an exceptionally good sounding solid state head. It can get quite loud and the overdrive is rich and focused. Sunn has always had a big “cool factor.”
