A-1 to A-25 : Orange/black ring label, Am Par Record Corp


A-26 to A-50 Transition from Am Par to ABC-Paramount Records Inc.



A-76 to A-100

At A-79, introduction of A/B suffix to catalogue number (except A-80):  A-##-A / A-##-B format.  Any title A-1 to A-78 with A/B suffix (e.g. A-33-A) is a later pressing, not original.



A-9126 to A-9150 Transition from ABC Paramount to ABC Records Inc. Mono increasingly found only on white label destined for radio play/ promo; commercial releases are stereo



Thereafter, AS-9166 and higher, the Impulse imprint became Stereo-only.

A few titles in the run up to A-9165 are not found in mono. The final run of mono releases may only have been white-label promotional copies destined for radio play.

This Guide relates to US pressing. European pressings, which were mastered locally from copy tape ( see ♪), may have continued with mono format for some time, insufficient information has been collected at this time.

Note – exceptionally, a European edition of an Impulse title has been seen bearing  Van Gelder stamp, indicating use of original US metalware . The title in question, Oliver Nelson Blues and The Abstract Truth, may be unique of possible one of a number of Italian Impulse pressed in this way. It was common practice between Prestige and UK Esquire in the late ’50s/ early ’60s so there is a precedent, but it is otherwise a rare form of overseas distribution.


Update: September 10, 2017

Eagle-eyed reader Rob G spotted this late series mono title, A-9152,  on orange/black label, among a hoard of white  promo label Impulse LPs, no doubt collection of a disk jockey or radio station.

Possbly a rare example of a promo issued on a regular label, but not a commercial mono release.

  1. If you can fill in any gaps, that would be more than welcome, email me. It is sensible to separate out promos from commercial releases, though that would leave large gaps in each series. I mixed them up but gave priority to promos as they are useful in corroborating “early/first pressing” detail, but with Impulse in transition from a mono and stereo label to all-stereo bar some promos, this is a mighty task.

    Right now I’m wrestling with a series on Jazzland/ Riverside, which has long been a gap in my label guides, but it’s a pig, the quality of ebay auction pictorial and written seller material is simply dreadful, some of the worst I’ve seen. Lower value items don’t get the attention given to Blue Notes. Onward onward.

  2. For what it’s worth I can verify the existence of orange label mono pressings of the following CAT #s which are not pictured in orange: 9137, 9144, 9145, 9146, 9149, 9150, 9155, 9157 & 9158. I can provide photos of most upon request. Despite the confirmed existence of orange label stereo counterparts I cannot verify the existence of orange label mono pressings of the following CAT #s: 9133, 9139, 9140, 9147, 9151, 9152, 9153, 9159, 9163 & 9164. If anyone has any evidence of orange label mono pressings of any of these 10 releases I would definitely like to see them.
