ISP Technologies To Debut Beta Bass Preamp Pedal at NAMM
ISP Technologies will be unveiling a new pedal version of their popular bass preamp at the Winter NAMM Show this month. The Beta Bass Preamp Pedal is powered by an external 9-volt AC adaptor that is then internally multiplied to provide plus or minus 15-volt power supply for a “full 30 volt signal swing.”

Its EQ section includes a bass and treble boost/cut knobs as well as two semi-parametric mids with separate sweepable frequency and boost/cut controls. ISP also loaded the pedal with their Time-Vector based compression, a phase manipulation exciter, and split-band distortion circuit, and a Decimator noise reduction control. Finally, an XLR direct output allows for easy connection to a mixer.
The ISP Technologies Beta Bass Preamp Pedal is made in the USA. It will debut at the NAMM show later this month and will carry a retail price between $429 and $449.
