The PDI 03 JB Speaker Simulator is a professional passive DI box for guitar amps. Providing a frequency compensated, transformer balanced direct feed to mixing consoles or soundcards it connects between the amplifier output and loudspeaker or equivalent dummy load. The PDI 03 JB has been developed for live, studio and home recording applications to eliminate the need for time consuming mic placement and mic-related problems.

Designed to Joe Bonamassa's high standards for a huge but tightly focused tone the exclusive JB switch brings the output signal to the fore and takes it "right in your face." The PDI 03 JB's dual speaker simulation filters are carefully voiced to authentically replicate the frequency response of classic and contemporary loudspeakers and cabinets. The unit's input sensitivity is adjustable for amps up to 200 watts or line and instrument level equipment.

Delivering consistent guitar tone from show to show the PDI-03 JB can also be used to add realistic speaker flavours to preamps and dirt boxes in direct recording applications. The rugged powder coated steel enclosure features high quality Amphenol connectors and a ground lift to remove hum resulting from earth loops.

For amp DI WITHOUT speakers a dummy load with matching impedance must be connected. We recommend the Palmer Power Attenuator PDI06 and the Palmer Dual Load Box PLB2X8.
