This one has eluded me for a while since it was a Q8-only release, but I finally received the tape today (White cart) and transferred it to DTS. Probably the most luck I've had with a used 8-track to date...new pad/spice and it actually started from the beginning.
Pretty good quad mix overall, with some cool four-corner discrete action in "Cisco Kid", though I was never a fan of putting the vocal in all four speakers and that does kind of spoil it a little. The sound quality wasn't bad compared to some other Q8s I've transferred recently (most Columbia ones I have sound awful, especially Chase), though I am curious about the gold cart version after reading through this thread.
I'd say it's an 8, but as with most quad mixes a high-resolution transfer from the master tapes would work wonders.
Could a Vocalion double SACD with this and "Deliver The Word" be possible??? This recent batch with the two Pure Prairie League albums makes me think anything can happen...
