Re-issue of 1967 API 550 EQ with an extra band
The API 550 EQ played a major part in the history of music recording in the USA during the 60's and 70's. Originally conceived for use in API's consoles, this latest 550 "B" version is a continuation of the original 1967 550, through the 550A, with one additional filter band and several new frequencies. Incorporating API's exclusive circuitry and proprietary components, (such as the legendary API 2520 op-amp), the 550B artfully blends the past with the present. So many hit records still depend on the unique 550 sound, that the 550B will be an invaluable tool you will turn to again and again. The API 550Bunlike any other you will ever use.
