Hmm..I never had trouble or spent a lot of time setting up equipment, mainly because I only had boomboxes back in the day.
No disrespect Restocat.
In my case I had both back in the dayz boomboxes and DJ equipment. When recording on a DJ equipment especially on a high end tape deck its about calibrating so you can have a nice well recorded tape. Back then I had your usual Technics 1200 turntables, Rane Mojo mixer, Crown amp, and a BBE for playback, but heres where the fun is: Rane Compressor, Rane EQ,Tascam DAT, and then the one and only AIWA XK-S9000 tape deck.
Thats where I say there is an art on recording and mixing is not just drop the cassette in and lets record. I have recorded on boomboxes but is not the same.
