This pre loved Ampeg PortaBass PB‑250 Head paired with the PB210H 2×10″ Cabinet, is a lightweight, gig‑ready bass rig from Ampeg’s early‑2000s PortaBass lineup and is in excellent condition.
Power & Tech: Delivers 250 watts RMS into 4 Ω using Ampeg’s Micro Dynamic Technology (MDT) amp circuitry—efficient and compact, avoiding heavy transformers or heat sinks.
Tone Controls: Four‑band rotary EQ with switchable ultra‑low and ultra‑high boosts and selectable mid‑shift frequencies for flexible tone shaping. Includes an Effects Loop with blend control and a transformer‑balanced XLR line output (pre/post EQ with ground‑lift).
Build: All-solid‑state housed in a compact, portable chassis; though lightweight compared to traditional amps, it doesn’t use Class‑D power and still retains modest weight.
Speaker Design: Dual 10″ drivers with neodymium magnets and a 1″ compression horn/tweeter. This approach reduces weight while delivering power and clarity.
Power Handling: Rated at 400 W RMS (600 W program) at 4 Ω, with a frequency response of 40 Hz–20 kHz and sensitivity around 93 dB.
Construction & Mobility: Crafted from lightweight Italian poplar plywood—strong and resonant—and features a removable telescoping dolly handle and casters for easy transport.
