The previous Maxell test run was done using a Sony TC-WE305 cassette deck and a Type 1 cassette. This one was done using an Akai MG614 (4 track recorder).
All of the samples were lifted off of 45s (vinyl/records). Hence the " Colt 45 ", emphasis on the 45.
I had a great time frequenting record shops, book stores, second hand shops, etc searching for 45s.
