Ampex / Quantegy 456, SP, 7″ Reel Tape, 1200 ft, Baked & Ready for Use The 456 / 457 Series are THE tapes made famous for sticky shed syndrome, especially since for a long time they were the undisputed sales leader for professional studio analog recordings in the 1970s and 1980s. These tapes offered excellent performance with noticeably higher output than any competing brands at the time. A successor to the 356 / 357, the first type 5 (high output +6) tapes produced. The MOL is so high that most older machines will reach their electronic limits before the tape distorts, which means most of the older machines cannot use their incredible capabilities. The 499s went one step further with an additional 3 dB of output. UPDATE 9/2023: When baked, these tapes are usable for at least a year after baking, which is enough for most recording projects. We now sell baked 456/457s and 499s in our store (if available) with the callout. Notes:You can identify this formulation by its brown oxide and back coating.The 456 Series represents the SP (Standard Play) version and the 457 is the LP (Long Play) version with the same oxide coating. No DP or TP versions of this formulations were made to our knowledge. The 499 was only available in SP.These tapes were excellent in every measurable way when new, which is why they were so often used for professional studio recording and mastering.Unfortunately like many tapes of this period, the back coated versions suffer from Sticky Shed and cannot be played without baking. DO NOT PLAY OR WIND THESE TAPES BEFORE BAKING. Unless baked first, winding them can cause the oxide to be stripped from the polyester base material, essentially destroying them. In fact, many batches cannot even be WOUND without baking as the oxide can be stripped off and the tape permanently destroyed. We have encountered some tapes that are less sticky than others, but there is no way to tell as the sticky shed condition seems to be dependent on the humidity of the environment they were stored in…and it has been over 40 years. If there is any valuable program material, these tapes need to be baked first.Ampex was spun off to form Quantegy in 1995. According to anecdotal evidence the tape binder was reformulated to eliminate the sticky shed syndrome, so Quantegy branded tapes *should* perform properly. Update 2023: SAD NEWS: We have confirmed that the Quantegy versions of 456/457 and 499 ALSO require baking as they are starting to go sticky.IMPORTANT NOTE (9/2023): Too many people trashed these tapes thinking they were total junk. This is not the case. They can still be used after baking. It’s easy with a cheap food dehydrator, they are $60. Anyone into the hobby should get one to make the sticky tapes playable again. They are usable for at least a year after baking, maybe longer. I have baked hundreds if not thousands of tapes. THERE IS NO REASON TO TRASH THEM WHEN THE FIX IS SO CHEAP.Available Refurbished: We only sell Quantegy 456/457 tapes in our store that have been thoroughly checked and where no Sticky Shed was found. UPDATE 9/2023: Baked 456/457s and 499s will be available in the store. They can be used for at least a year after baking (research is ongoing to determine if they last longer). Quantegy branded tapes will also be baked. What are refurbished tapes? First, we only select tape formulas for refurbishment that have proven to withstand the test of time and will be reliable. Tape formula and length are verified to match the box type, so you know what you are getting. All tapes have been wound, cleaned, and checked to make sure the entire length of the tape is defect free (no folds, bends, tears, splices, stretches, or oxide shedding). All tapes are bulk erased, if Priority Mail is selected. To comply with the low cost Media Mail rate requirements, tapes will be sold as pre-recorded with the content on them. All tapes are free of mold, dirt, and water damage and in good condition. Reels are placed in a plastic bag and sealed with a label once it has passed our quality control check. The package is renewed – the box is either shrink-wrapped, the RR label is affixed to the box, or an insert is placed in the box. 30 day no fuss replacement guarantee – if you find a problem with the tapes or are not satisfied for any reason, we’ll send you a replacement tape. Buy with confidence!
