@tomic601, for years I too thought the Basement Tapes were recorded on a Revox A77 (perhaps because that is what is pictured on the front cover of the official LP release ;-). But in his book Testimony, Robbie Robertson lists the recording equipment Garth Hudson used in the basement of Big Pink all throughout 1967:
- A half dozen Norelco mics (dictation mics?!).
- A couple of "little" Altec mixers.
- An Ampex 2-channel/4-track stereo reel-to-reel recorder (consumer, not pro), running at either 7.5 or 3.75 ips.
- Two speakers for playback listening.
- Headphones on which Garth set mic levels.
Thank God for Garth Hudson!
