The Stinger Pro Bass series also includes five combos designed to give professional features in portable packages. The ST P150B is a 150-Watt combo version of the STP300HB head with a built in 15-inch driver and a piezo tweeter. Adding an external 8 Ohm speaker, this combo will put out 200 Watts RMS. The ST P75B is designed to be the ultimate in facilities for a mid-sized stage amp or studio amp. The compressor and equalizer are foot-switchable, there is a pre- or post EQ balanced output with a level control, an effect loop with input and output level controls, adjustable pre-shape and input gain controls…the works. In stand-alone operation it puts out 75 watts RMS to a 15-inch driver and, add an external 8 Ohm or 4 Ohm cabinet for 100-Watts RMS total output. The ST P50B has just enough power for recording studio and offers straightforward controls. It’s equipped with high and low gain inputs, pre-shape, a three-band EQ, and a presence booster. It’s deep cabinet gives it excellent low-end for a very portable combo. For rehearsals and home studios, we designed the ST P25B to give you all the body needed for small applications, with professional sound and construction. Theses combos are all housed in tuned, heavy-duty enclosures loaded with purpose-built speakers protected by sturdy, metal grills.
