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.


One thought on “Impulse! Complete 1st Pressing Label Reference Set: Mono (1961-8)

  1. 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.
