Product Description

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 Pre-Distort Preamplifier, Theta High Gain Distortion Stage and, to keep things quiet, a full implementation of the award winning Decimator G-string II circuit.

Features:

- Pre-Distort Preamp usable for overdrive of Distortion circuit or for clean tone shaping / overdrive
- Incredible tone shaping with Pre-Distort tone includes Bass, Mid Level, Mid sweep from 300 to 3KHz and Treble
- Theta Distortion circuit with post-distort Bass, Mid Level, Mid Sweep from 300 to 3KHz and Treble
- Highest gain Distortion available anywhere, greater than 160dB of gain using Distortion and Pre-Distort Preamp overdrive
- Decimator G-string II noise reduction built in for absolute silent operation and greater than 80dB NR
- Footswitch selectable dual Gain1 / Gain2 settings
- +/-15volt internal operation for professional headroom and sonic clarity
- Dynamic Saturation Modulation circuit emulates a saturated tube amp with tube rectifier
- Externally controllable switching of all footswitch functions for control via MIDI control function

The Preamplifier section includes controls for Gain, Bass, Midrange boost/cut Level, Midrange Sweep from 300 to 3KHz, Treble and Preamp Level. The 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 Decimator improvements of Linearized release response, which improves the smoothness of the release response of the Decimator.

Another incredible feature USP 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 performance. The trademark sound of the Theta amplifier series is over-the-top gain and sustain with over 160 dB 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. 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.

The Theta Preamp Pedal is a truly 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.

What The Pros Are Saying...

"The Decimator Products (ProRackG and Pedal) I have acquired are the most organic sounding noise suppressors I have encountered. You can dial each in to be as gentle or as tight as you wish without having any harshness when it engages." Josh Elmore, Cattle Decapitation

"Other than my guitar and amplifier, the ISP Decimator is the one piece of gear I value the most. It is the greatest noise suppressor on the market." - Mike Spreitzer, Devil Driver
"For me the ISP Decimator pedal is the enforcer of clean tone and signal without the loss of sustain. It Rocks!" - Johnny Hiland

"This ISP Decimator may be the most effective noise reduction pedal on the market today. Its operation is completely transparent -- and its operation is totally flawless. Once you turn it on, you'll never turn it off!" - Eric Kirkland, Guitar World Magazine

Customer Reviews
5 out of 5 (3 ratings) Rate and Review This Product
zZounds has verified that this customer bought this product from us. "Jaw Dropping Options and Sound"
Overall: Have you ever wanted to play and not have to worry about what you will have to carry to a GIG? Want something that works with everything? I purchased this stomp box from Zzounds last Thursday (SEPT 19, 2013) I asked that it be delivered overnight, it would be there when I arrived home early Friday, before lunch. Ok let us get started you have the run down. I opened the shipping box to find the pedal and a USER guide. I read this immediately as I had bought the pedal on a demo I saw on YOUTUBE from the ISP Site. After some reading I decided to put the pedal through its paces. First I used the front end (guitar jack) of a Fender Ultimate Chorus. I set the clean channel and the Reverb and Chorus, to use the functions from the amp as well, a little more versatility. It sounded like the amp was just screaming and at the limit. When I stopped playing the amp hissed like a den of vipers, but there is the ISP Noise Decimator built right in (one of the reasons to choose this Pedal) just turn until you hear nothing, and stop. I ran the rig full blast and on the edge of unimaginable gain, dead silent until you play your guitar. There is a preamp section that you can use if you choose or not, (you can use your clean and the preamp if you like) you will want to get all of your levels adjusted. I set the clean and the preamp up to sound close to the same volume with the preamp slightly lower than that of the amps clean. (Again more options) there are two gains below in the Gain and Overdrive section. They share the same EQ settings and of course there is more than enough gain to get you where you want to be I was amazed at how much Gain this pedal can provide. If you need more than this pedal can provide you will have to wait until someone creates one (this is it, I am telling you). I basically set this up to be a four channel affair. IT works like this I have two clean channels one louder than the other for boost, same for the Gain setup.. you can use the Overdrive this will let you select Gain 1 or Gain 2 , if you set the preamp volume correctly you can deselect the preamp section and get another boost for leads and such. READ the manual, it will tell you what I had to learn even after reading it. The Knobs ALL allow for Boost/Cut, yes that is right you cannot just adjust the tone sound wise but you can actually add and/or subtract volume within that range as a parametric EQ. Amp after Amp worked with this setup. Some will want to use the Effects loop; if you do you will lose some of the versatility...but none of the tone or usefulness. I recommend the front end of your amp, if you have two inputs move the cable form one to the other most amps allow for High input guitars or guitars with active pickups. I used this setup with solid state and tube amps, A fender Twin and a two different Mesaís Rectifier and a Mark V. I have a Marshall JCM 900 Lead Series. In each and every case this thing screamed as if it were about to blow the roof off of the place. I intentionally go for this sound and it requires a lot of attention to keep it reigned in and in control. I cannot say enough about the Decimator Noise Gate, IT is so simple and yet it allows you to run that gain to catastrophic heights. We are talking apocalyptic noise appreciation. Let your neighbors tell you how much better you sound or do what I did, I went our Saturday and for practice Sunday. The one thing after every song and break was, damn that sounds amazing, how much and how easy? I think Zzounds will sell many more. If you have not heard of ISP Technologies, you are not alone, they donít advertise because every person that uses or is exposed to their products is a client and an endorser. I wish you well and hope that my goal to assist you is successful. CJWII
