Up for sale, a 1968 Sunn 2000s vintage tube bass amplifier head in excellent condition and in perfect working order. The brainchild of Norm Sundholm, bass player for the Kingsmen, and his brother Conrad, the Sunn company was birthed out of the need for gear that reproduced powerful, rich clean tones that could compete on the world's largest stages (not the least of which was Woodstock, where Sunn supplied the backline). The Sunn 2000S led that charge in the bass world, and the hi-fi clarity and sweet warmth of this all tube bass head is oft-copied but rarely replicated. With absolutely massive transformers and a dual rectified four 6550 tube powered circuit, this 2000S head delivers incredible cleans with respectable headroom and some more aggressive, growly tones when you really open up the Volume knob. The list of Sunn bass amp users is prolific and includes Geddy Lee, John Paul Jones, John Entwistle, and Noel Redding.

This 2000s head has been recently serviced, with a complete and professional recap of the power supply, as well as a modern three-prong power cable. The power tubes are a fresh quad of Tung Sol 6550s which been properly biased for optimal headroom and life. The rest of the tube compliment consists of a pair of NOS 5V4 rectifiers and dual triodes from the likes of Amperex and General Electric. The original CTS pots and pair of chokes have date codes from early 1968, and both transformers are made by Dynaco. While the output transformer is the more conventional Dynaco style seen in Sunn amps, the power transformer is an arguably earlier example that could very well be original as well, although the cosmetic differences between the two transformers are notable. Regardless, the 2000s is designed to be powered by Dynaco iron, and these transformers sound incredible.

The head retains all of the original hardware along with the original set of witch hat knobs and Sunn badge on the grillcloth. The original tolex shows only light scuffs and nicks and moderate aging of the grillcloth.
