Waterford, MI (December 19, 2012) The ISP Technologies Theta Preamp PEDAL brings the full performance of the High Gain section of the Theta
amplifier and Theta Rack-mount Preamp down to a foot pedal based Preamplifier pedal.
The Theta Preamp
pedal includes a full Preamplifier, Theta High Gain Distortion Stage and to keep things quiet, a full
implementation of the award winning Decimator G-string II circuit. The Preamplifier section includes controls for
Gain, Bass, Midrange boost/cut Level and Midrange Sweep from 300 to 3KHz, Treble and Preamp Level.
Preamp section can be used stand-alone for clean tone shaping and/or used to overdrive the front of the Theta
High Gain distortion stage. The Distortion controls include footswichable Gain 1 and Gain 2 for selection of a
crunch and over the top gain, Bass Midrange boost/cut Level, Midrange Sweep from 300 to 3KHz, Treble and
output level. The Decimator G-String II circuit has a Decimator Threshold control and provides the full Time
Vector Processing circuit with the latest Decimator improvements of Linearized release response, which
improves the smoothness of the release response of the Decimator. Another incredible feature we added is
Dynamic Saturation Modulation, which emulates the spongy modulated dynamics of a full throttle tube amplifier
with a vintage tube rectifier power section. While subtle, this adds yet another dimension to the Theta
The trademark sound of the Theta amplifier series is over the top gain and sustain with over
160db of gain on tap and incredible tone shaping flexibility. The front end Preamplifier can be used to over-drive
the input section of the Theta distortion circuit with mind blowing amounts of gain and pre-distort tone
shaping. The only way we can provide this level of gain is due to the inclusion of the on-board Decimator G-String
II circuit, which tracks the envelope of the input signal and provides greater than 80db of noise reduction.
Theta Preamp pedal is a true professional guitar Preamplifier with an internal +/-15 volt power supply
providing more than 3 times the headroom of a typical 9 volt pedal. This amount of headroom is required for
proper tone shaping and a higher level of performance than would otherwise be possible with a standard 9 volt
power supply. Add to all of these features dual remote control jacks, which allow all of the Theta Preamp
pedal switch functions to be controlled via MIDI control functions or simple switch closure, and you have one
powerhouse Guitar Preamplifier. The Theta distortion circuit is in a class of its own with better sensitivity,
response and tone than any other guitar Preamplifier. The discerning player knows how much better you can play
when the response between their fingers and their ears becomes magic. That is the definable level of
performance that the Theta provides.
