Hi there. I am investigating reel to reel recorders to master an album I have recorded digitally, as I wish to add the warm analogue sound. I am keen to get a valve model for maximum warmth, and of course since it's for mastering, the wider the tape with the least number of tracks, the better. I have found an Akai 1710 for sale for a good price - is this suitable? I am aware it is a 4 track machine, but is it also possible to use the whole width of the tape for just 2 tracks? Otherwise, what other decent options are there?
