The ISP Technologies Theta preamplifier offers a unique approach to the guitarist, providing two selectable input pre-distort preamplifiers. Using the Theta preamp is like having two low-noise, extremely high-quality preamp pedals at the input of the amplifier. Each front end preamp has gain, bass, mid level, mid sweep and treble which provides amazing pre-distort tone shaping. The amplifier's "Clean" and "Distort" circuits have the same post-distort tone shaping.

The Clean channel has additional tone shaping with the inclusion of a Presence control providing more than 20dB of high frequency boost. You want gain? The Theta Preamp has over 160db of gain you can control and make usable only because we've included dual independent full-featured Decimator Noise Reduction systems. The Decimator defines a new standard for excellence in real time noise reduction performance. The Decimator was designed to provide the maximum possible performance in a noise reduction system designed specifically for extremely high gain guitar amplifiers.

The Thea Preamp Decimator is designed with dual channels of single ended noise reduction. Configured specifically for high gain guitar applications. The Theta preamp is the first to incorporate "Dynamic Saturation Modulation," which delivers the actual feel of a saturated tube power amplifier. Shipped with a 6 button footswitch to control all of the parameters of the Theta and comes with the interconnection cable.
