Reducing the footprint of my studio and selling some gear. This is the Manley Massive Passive. The EQ is passive. Tubes make up the gain the network loses. Four bands a side, and every band can be a bell or a shelf, boost or cut. The bands overlap, so you shape by ear. This is the standard version with continuous knobs, not the stepped mastering version. Smoke-free studio. Light rack wear. Everything works. 120V. Famous for a reason.
