Page 2: Power Requirements
Decimator II G-String noise reduction system. The THETA Preamp Pedal can be used as a dual channel preamplifier with both a clean preamp and distortion channel or with the front end preamp overdriving the distortion for massive high gain. - Page 3 The rear panel has 4 ¼ inch phone jacks with one for the guitar input, one for the final output signal and two remote jacks which allow the THETA preamp pedal to be switched remotely by switch closure (pull to ground) or with relay functions under MIDI control.

+/- 15 volt DC power supply. This allows a 30 volt internal signal swing required for proper headroom and professional level performance. The THETA pedal will only operate on a 9VAC power source, do not use any other power adaptor or damage may result. - Page 5 THETA pedal. This means you can switch from the clean PREAMP to low gain and even high gain plus ultimate gain with both the PREAMP and DISTORT circuit in use and still eliminate all of the noise at the output and all with one threshold setting.

Page 6: Treble Control
BASS This control adjusts the amount of boost or cut in the low frequency portion of the spectrum of PREAMP. The available BASS boost and cut range is +/-15 decibels. Note: the Bass control is flat when the control is centered at 12:00. MIDRANGE BOOST/CUT CONTROL This control works in conjunction with the SWEEP frequency control. - Page 7 DECIMATOR CONTROL NOISE REDUCTION CONTROL The DECIMATOR control adjusts the THRESHOLD of the Decimator G-String II. The Decimator works with both the Clean PREAMP and the DISTORT circuit and will switch completely out of the signal path when both the PREAMP and DISTORT circuits are switched off.
- Page 8 DISTORT CIRCUIT DISTORT ON LED This led located above the DISTORT FOOTSWITCH and indicates when the DISTORT Circuit is active and in the signal path. GAIN 1 / GAIN 2 CONTROLS This control adjusts the amount of gain in the DISTORT CHANNEL. The maximum amount of gain will be determined by the setting of the Active GAIN control selected by the GAIN FOOTSWITCH.

Page 9: Getting Started
SETTING THE THETA CONTROLS GETTING STARTED It’s best to start with a flat response and adjust from that starting point. The THETA can be used for virtually any sound you are looking for but it will be easiest to dial in your sound with the controls set flat. - Page 10 For clean tones use the clean PREAMP and adjust the bass and treble for the desired tone and then adjust the mid and mid-sweep settings. For a more forward sound try boosting the midrange above 12:00 and sweeping the mid between 10:00 and 2:00. For a more scooped or hollow tone pull the midrange back below 12:00 and adjust the sweep for the preferred frequency.
- Page 11 In this setting use GAIN1 or GAIN 2, PREAMP OFF, DISTORT ON and adjust to find that classic 80 tone based on your specific guitar, power amplifier and speakers used. THETA SPECIFICATIONS Input Impedance 500k ohms...
