For fx and MAYBE mixdown purposes I have gotten a otari mtr 12 1/4" 2 track. Its been near 5 years since I last worked at a studio with analog machines and it seems tape has changed a bit. I checked for 499 as I want to hit it plus 9, but no store seemed to want to carry Quantegy, who carries Ampex( thats how long I been away) they had some basf 900 and 911 or something. which one will handle +9 at 30 and 15 ips well? does basf still ruin tape heads?
