There must be major differences between your test setup and a real shifter
because I have used frequency shifters and with normal music running through
them any artifacts are very difficult (if not impossible) to hear in fact
inaudible to me, certainly a long long way from your 'Completely
unlistenable' as far as feedback killers are concerned I have found
frequency shifters to work very well even better than the Sabines.
I am almost willing to bet that the guitar is unlikely to be tuned
