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 Pro Rack Noise Reduction Processor delivers a revolutionary breakthrough in noise reduction with an unparalleled level of performance. From the original inventors of the HUSH noise reduction comes the latest, most advanced, patent pending, state of the art technology in real time noise reduction. 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 both very short-term staccato notes and long slowly decaying signals. 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 Pro Rack uses both Dynamic filtering and low-level downward expansion. A Time Vector Processing circuit controls the release response of both the downward expander and dynamic filter. The input of the Decimator Pro Rack is TRS 1/4-inch balanced to eliminate any common mode noise. Both channels can be used at a –10 or +4dBU reference level. ISP Technologies has also designed the Decimator Pro Rack using high quality studio grade voltage controlled amplifiers for both the dynamic filer and downward expander. This provides dynamic range noise performance of greater than 118db. This translates into the most transparent noise reduction system you†ve ever heard. The Decimator Pro Rack is extremely easy to use; simply inset the Decimator at the end of your signal chain or, insert the Decimator Pro Rack 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 single space 19-inch rack, the Decimator Pro Rack offers the highest possible performance in a single ended noise reduction system, period. - 365.80

The Beta Bass Preamplifier offers the professional bassist the highest level of performance ISP Technologies can provide. By incorporating patented Time Vector Processing, the compression circuitry becomes the most adaptive to be used in a bass processor as it allows the Beta preamp to truly track the signal of the notes played. Add in the patented Decimator Noise Reduction Technology, and you have a bass processor with built-in noise protection! With two parametric bands (a low-mid and a high-mid), bass, treble, bright, and an exciter (for phase manipulation), the Beta lets you shape your sound to your own specifications. For absolutely unsurpassable performance, pair the Beta Bass Preamp with the ISP Technologies Bass Vector or Bass Vector Pro cabinets and get up to 4000 watts of bass depending on your choice of configuration! - 643.50

Tired of the limited performance of 4x10 bass cabinets? With the Bass Vector Pro, ISP Technologies has taken a different approach to the modern bass guitar system. Combining the low frequency extension that only an 18' driver can achieve with the natural, extended (but not brittle) highs of dual 8' drivers, the Bass Vector speaker cabinet achieves a balance of depth, impact, and definition that makes 4x10's sound lifeless by comparison. At low frequencies, a single Bass Vector exceeds the output of a typical 4x10 cabinet by 4dB or more at 40Hz. A single powered cabinet delivers 600 watts RMS to it's speakers. When an additional passive cabinet is connected, the amplifier delivers a total of 1000 watt RMS to the two cabinets. The total system power can be further increased by adding additional active and passive cabinets with a limit of 1 passive cabinet per active cab. The ISP Beta Bass Preamplifier is the ideal 'head' for the system, or the active cabinet can be used with other bass heads when driven from their line output, and the passive cabinet can be driven from virtually any powered bass head. The high performance 18' driver is complemented by an advanced speaker cabinet design featuring optimum volume and a large, deep tuned port. This helps to minimize the non-linear behavior and reduced low frequency output that small ports produce. The Bass Vector Pro is tour grade, with Baltic Birch plywood construction, dadoed joints, extremely durable rubberized polyurethane finish, metal handles, and casters. - 2,299.50

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.

The Fetish guitar effect pedal can be used as an overdrive, distortion, clean boost, or treble booster depending on settings. And with the addition of its variable 'fat' control, it provides body and depth to a variety of settings. Packaged in a rugged, beautifully polished smooth chrome chassis as the Decimator Pedal, the ISP Fetish will be an awesome addition to your pedal board! For Modern Rock, the Fetish can be used as a boost in the front end of the amp for extra sensitivity. For Classic Rock, there is enough gain to duplicate the gain of a classic stack. The gain structure has the ability to clean up with a flick of the volume control on the guitar. The guitar pedal can also be used as a boost for Blues oriented styles without changing the voicing of the amp. Also, as the ISP Fetish pedal is boosted in the clean setting as the level is increased, the signal pushes a final stage in the circuit to allow for a creamy overdrive effect. - 123.99
