ISP Technologies introduces the 400-watt Theta Combo. Continuing the ISP tradition of innovation, the Theta guitar amp offers a unique approach to the combo amplifier, putting the performance of the amazing Theta guitar system and the world-renowned Vector active guitar subwoofer technology in a single, lightweight combo package. With 100 watts RMS driving the Celestion speaker and 300 watts available to deliver the thunderous low end the Theta Combo really delivers on sound.
The Theta Combo provides 2 selectable input pre-distort preamplifiers. Using the Theta Amp is like having 2 low-noise, extremely high quality preamp pedals at the input of the amplifier. Each front-end pre-amp has gain, bass, mid level and mid sweep 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 has greater than 150db of gain and you can control it and make it useable because of the included dual independent full-featured Decimator Noise Reduction systems. The Theta Combo incorporates "Dynamic Saturation Modulation"™, which delivers the actual feel of a saturated tube power amplifier. The Theta Combo also packs a huge punch; the internal D-CAT power amplifier delivers 100 watts RMS into a 12-inch Celestion guitar speaker and 300 watts into a second 12-inch, high excursion woofer. Derek Bowers, renowned IC design engineer from Analog Devices and Buck Waller of ISP Technologies, developed the patented 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 fantastic transient response and punch.
