Monstrous power you can shape any way you want.
The Theta Amp Head offers a unique approach to the guitar amplifier, providing two selectable input pre-distort preamplifiers. Using the Theta guitar amplifier head is like having two low-noise, extremely high quality preamp pedals at the input of the amplifier. Each front-end pre-amp 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. Tone beyond your wildest dreams! Extreme sonic flexibility. 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 amplifier head has greater than 140dB of gain and you can control and make it useable because of the included dual independent full-featured Decimator Noise Reduction systems.
The Theta incorporates Dynamic Saturation Modulation™, which delivers the actual feel of a saturated tube power amplifier. The Theta also packs a huge punch; the internal D-CAT power amplifier delivers more than 300 watts RMS into a 4-ohm load and 150 watts into an 8-ohm load. Derek Bowers, renowned IC design engineer from Analog Devices and Buck Waller of ISP Technologies, developed the patent pending D-CAT power amplifier technology. The D-CAT is a super high current power amplifier technology capable of driving a .5-ohm load. This means that the D-CAT amplifier delivers excellent transient response and punch.
