During that time the company changed hands and the model went through a variety of incarnations. Despite these several changes, the LA-2A has remained one of the most popular tools in the recording studio, beloved by engineers for its program-dependent compression and ease of use. Beautiful for vocals, bass, guitars, overheads, drums, etc. \u003c\/p\u003e\u003cp style=\"margin: 0px; padding: 0px; box-sizing: border-box; color: rgb(38, 38, 38); font-family: Arial, Helvetica, sans-serif; font-size: 13px; background-color: rgb(255, 255, 255);\"\u003eEssentially there are six different versions of the LA-2A, based on various design elements, parts, outward appearance, and parent companies. The six revisions can best be classified as: Revision 1 (the original); Revisions 2A, 2B and 2C (all inter-related in various ways); Reissue 1 and Reissue 2. The first four versions kept consecutive serial numbers, while the two reissues had their own numbering scheme.\u003c\/p\u003e\u003cp style=\"margin: 0px; padding: 0px; box-sizing: border-box; color: rgb(38, 38, 38);
