The patents-pending Vector SL 600W Active Guitar Subwoofer Speaker was developed in collaboration with one of the most prolific guitarists of our era: Steve Lukather. Because of a long-standing relationship with Buck Waller of ISP Technologies, Lukather came to Buck with his desire to see a guitar subwoofer that would work with any guitar system. Based on specific inputs from Lukather, ISP engineers have designed the perfect complement for any guitar setup: the Vector SL Subwoofer. Years of experience in designing the highest performance Active Sound Reinforcement cabinets has allowed ISP Technologies engineers to develop the ultimate Active guitar subwoofer. The Vector SL incorporates ISP's patent pending D-CAT power amplifier technology with greater than 600 watts of RMS power. Connect the output of any guitar head to the Vector SL and plug in your favorite speaker cabinet and your supercharged Lukather Vector SL system is ready to ROCK. The subwoofer level is adjustable via the sub level control on the back of the Vector SL cabinet. The internal 600-WATT RMS Active 15-inch subwoofer delivers incredibly deep, low end. The Vector SL subwoofer extends your bottom end all the way down to 45Hz, delivering enough low-end bass to match the frequency response of any 7-string guitar. Tune down as far as you want and the Vector SL continues to perform. To all this performance, add three-way power amplifier protection and you have a supremely reliable active guitar subwoofer. The Vector SL's internal D-CAT amplifier has global thermal protection, thermal protection built in the power transformer, and an on board distortion limiter circuit to eliminate the possibility of feeding square waves to the woofer. This means that, as long and hard as you drive the Vector SL, even to its maximum limits, you never have to worry about failures. - 1,498.06

The ISP Technologies Decimator G String Noise Reduction Pedal delivers the performance of the Decimator Pro Rack G in a compact pedal. The Decimator G String provides a totally independent channel of Decimator noise reduction that can be inserted into a series effects loop or after a preamp section with the advantage of having the Decimator level detectors track the guitar signal directly. With the G String pedal you can set the threshold and no matter what level of noise the Decimator will track perfectly without any side effects. And the amazing thing is that you can switch from high gain to your clean channel and never have to switch the Decimator G String off due to the threshold being set too high. It†s simply transparent. As can be seen in the diagram, the G String noise reduction pedal has an input to connect a guitar directly and a buffered output signal to feed the front of a guitar rig directly while providing a separate audio channel of Decimator that can be inserted in the signal chain of any guitar rig. You can insert any other pedals between the output of the Decimator G String and the input of your guitar amplifier. This allows the Decimator G String pedal to remove any level of noise you may have even with overdrive pedals at the front end of the amp. - 219.95

The ISP Technologies Decimator Noise Reduction Pedal features the latest, most advanced, state of the art technology in real time noise reduction. The Decimator offers a revolutionary breakthrough in noise reduction processing with an unparalleled level of performance. The HUSH system, as well as all other noise reduction systems suffers from one major problem inherent in their design: The system cannot be immediately responsive to very short-term staccato notes. The typical downward expander noise reduction system suffers from a dead zone in the release response characteristic which causes a compromise in tracking both fast decaying notes and long sustained notes. The Decimator design offers a novel approach to tracking the envelope of the input signal called Time Vector Processing. Due to this novel approach in controlling the expander, the Decimator system will instantly respond to short staccato notes and, at the same time, will provide a very slow ripple free control of long sustained notes. This means that the Decimator noise reduction system is the most transparent and highest performance noise reduction system available. The Decimator Pedal is extremely easy to use; simply inset the Decimator at the end of your chain of existing pedals or, insert the Decimator Pedal in the effects loop of your amplifier to clean up the noise present at the amplifier input as well as the noise in the amplifiers pre-amp section. Packaged in a rugged, beautifully polished smooth chrome chassis, the Decimator pedal offers reliability, performance and beauty in one compact pedal. Audition the Decimator today and experience the highest level of performance available in a noise reduction system. - 129.95

The ISP Technologies Decimator Pro Rack G Noise Reduction Processor defines a new standard for excellence in real time noise reduction performance. The Decimator Pro Rack G is designed to provide the maximum possible performance in a rack mount dual channel noise reduction system designed specifically for extremely high gain guitar amplifiers. The Decimator Pro Rack G is the only system in the world designed with two channels of single ended noise reduction configured for high gain guitar applications allowing one channel to deliver noise reduction for the guitar directly and a second channel to eliminate amplifier gain noise. Channel one eliminates the 50 or 60 cycle hum, buzz, stage light noise and any other noise picked up directly by the instrument. The control circuit of the second channel detects and tracks the guitar signal directly while the signal processing audio chain is patched into the effects loop of the high gain guitar amplifier. Now you can quiet down even the most insane amounts of noise with any amplifier system incorporating a series effects loop. The Decimator Pro Rack G will also solve the typical high gain feedback or squealing problem that the high gain guitar player fights. You know how difficult this problem can be. You play staccato notes and in between each note you have a squeal or burst of feedback that's virtually impossible to control. Problem solved with the Decimator Pro Rack G. By proper setting of the threshold for channel one and channel two you can eliminate this problem for good. The Decimator Pro Rack G has dual processing channels incorporating both low-level downward expansion and dynamically controlled low-pass filtering in a very easy to use single rack space unit. Not only does the Decimator Pro Rack G deliver the most stunning noise reduction, it also solves the problem of needing to adjust the Threshold setting every time you change gain or switch channels. By using the input guitar signal to drive both channels' level detection circuitry, the Pro Rack G needs no other adjustments once the thresholds are set based on the guitar input. This will give you the correct threshold with clean, crunch and even monstrous amounts of gain and if you use pedals you can insert them in the loop between the output of the Decimator Channel 1 and the input of the guitar amplifier. The ISP Technologies Pro Rack G Stereo Noise Reduction Processor is the perfect solution for your noisy stereo guitar rig. The Stereo version provides an extra channel to provide noise reduction for two separate effects loops or stereo channels.
