Well, as I said, it was an acoustic band, and AFAIK Alan didn't try to 'jazz it up' in any way, just a direct mic feed. Alan aims for as 'natural' a sound as possible with his recordings. Monitoring during the recording was done on headphones.

Pink Floyd certainly experimented with electronics, that's true. But they used plenty of 'real' instruments, too. You can hear them quite easily on a decent system.
