4-Band EQ
The API Select SV14 EQ circuit design is rooted in API's history. Faithfully re-engineered from the highly sought-after APSI 562 EQ's which were distributed by API during the 1970's and 1980's, the SV14 provides parametric equalization at an affordable price point. The SV14 also features an EQ in/out switch, transformer balanced output, and dual concentric knobs which provide continuously variable control of boost/cut and frequency selection.
These merchants probably sell this module. Huh?
