Keeley Time Machine Boost.

The Keeley Time Machine Boost is a two-channel guitar preamp and booster effect pedal. It delivers a range of powerful guitar tones and is extremely effective for driving your tube amp into overdrive or saturation. The two channels are vintage and modern. The Vintage channel is inspired by the highly coveted and sought-after vintage germanium boost pedals favored by guitarists worldwide. The Modern channel gives you 23dB of pure, clean, transparent gain fueled by dual JFET transistors. The use of a special voltage-doubling IC gives the Time Machine lots of headroom. As with all Keeley-built electronics, this preamp and boost pedal incorporates top-of-the-line audiophile-quality parts like silver solder, teflon-coated wiring, and metal film caps and resistors.. ...details

Keeley Fuzz Head.

The Fuzz Head from Keeley is a unique lead boost that combines the best of fuzz and overdrive effects. Transparent, dynamic, and fully tweakable, with an NPN Germanium transistor at its heart but much more up its sleeve.With external Fuzz and Head controls, you can easily call up a number of dynamic fuzz and overdrive effects. The unique Si/Ge switch allows you to control a secondary clipping stage by adding a pair of diodes (one Germanium, one silicon) into the circuit for smoother clipping, more saturation, and loads of sustain.Pedal tweakers will love the internal gain control, which sets the overall range of the external Fuzz control, and the internal tone control or sharpening high-end or cutting it back. A small, flathead screwdriver is all that's needed to fine tune your tone. Three swappable capacitors are also included with the Fuzz Head, so that if you must change the low-end response of the pedal, you can.. ...details

Keeley Modded Boss SD-1 Stacked IC's and Clipping Switch Guitar Effects Pedal ¹.

The Keeley SD-1 has a great tone to start with, but now every component added is of the highest quality. Metal film capacitors are used to provide the smoothest midrange and high frequency components to your tone while increasing the bass response of the effect pedal. Metal film resistors are used in all of Keeley's changes to give the guitar pedal a consistent sound with extremely low-noise. In addition the BOSS switching has been improved making it even closer to true-bypass.Keeley stacks two TI4558P chips for much better distortion, articulation, and transparency, while generating less noise. These two TI chips work in parallel, mounted on top of each other and soldered together.Secondly, the Keeley Modded Boss SD-1 pedal includes a two-way gain switch that lets you select between two different diodes for the clipping/distortion section of the guitar pedal. The "down" position selects a germanium diode. The diode clips the signal more than a standard silicone diode, providing a more saturated, compressed, and smoother sound with more distortion available. The Keeley pedal's "up" position selects an LED for the clipping section, which clips less, allowing a clearer, more "open" sound, with less compression, more dynamic response, and more output available. Both are asymmetrical and both are an attempt to make the pedal more "tube-like," since tubes and transformers rarely produce symmetrical distortion. Some modifications simply take out one of the Keeley SD-1's stock diodes and call that sufficient. Keeley gives you a much wider range of professional tones.All of the stock the Keeley SD-1 Boss wah pedal settings are still possible throughout the midrange of the control. Plus, none of the singing sweet midrange tone is gone. But you will also notice that your Keeley Boss SD-1 pedal has an improved bass response due to careful changes in the pedals design. Again Keeley used metal film caps to ensure the best tone possible.A recommended starting point: All Controls set at 1 O'clock, toggle "down.": good biting drive and gain. Set the Level to 3 O'clock, Drive at 9 O'clock, and toggle switch "up," and the tone anywhere that sounds good to you. This is a good boost and great for distorting the input of a tube amp. Set the Level to 4 O'clock, Drive off, and toggle switch "up." This is an ideal clean boost. Set Drive to 4 O'clock and the Level to 12 O'clock and toggle switch "down." This is a super GE sustain setting. The Keeley Modded Boss SD-1 effect pedal is great for lead work that is very saturated while retaining the essence of your guitar!. ...details

Keeley Modded Boss DD-3 Analog Switch and Effects Loop Guitar Effects Pedal ¹.

There are two parts to Robert Keeley's mod of the Boss DD-3 digital delay pedal. First, he adds switchable analog feel to this industry-standard compact delay by incorporating two different smoothing capacitors. Use the small three-way switch to select between these caps or the original stock sound of the DD-3.The second mod takes the DD-3's direct out and turns it into an effects loop, allowing you to add any external effect just to the DD-3's repeats. Add slight chorus or phase to the signal to simulate tape effects, or experiment to find whatever your imagination wants!. ...details

Keeley 4-Knob Compressor Guitar Effects Pedal.

Keeley's most popular pedal, the Keeley compressor has become an industry standard for stomp box compression. The sound will inspire, and your music will flow freely—just plug the compressor pedal in and let your head, heart, and fingers fly. The sound quality of the Keeley compressor is rarely heard in the stompbox arena and is only seen in very expensive rackmount or tube equipment.It is a true audiophile and studio-grade compressor, with exotic rackmount-quality in a stomp box. The Keeley compressor pedal ships with the 9V DC jack at the top end of the guitar pedal and use the same type of power supply used by nearly all guitar effect manufacturers.Internal Attack Control The compressor pedal has an Internal Attack control, designed for bass players with high-output active pickups or active pedal boards with buffers. Sensitivity Control The Keeley compressor pedal also has an Input Sensitivity Control, meaning you can use this in your studio to run keyboards, drum machines, drum mics, even master recordings and other line-level uses. You'll raise your signal to a new level of sonic awesomeness. True bypass switching circuit True bypass means that when the effect is off your guitar tone will not be affected at all. The true bypass circuit makes sure you have absolutely no tone loss or signal reduction through the compressor pedal in the off/bypass mode.Triple-pole double-throw switch This switch makes sure you have absolutely no tone loss or signal reduction through the Keeley 4-knob compressor even in the off mode. Other compressors use a cheap switch and design that runs down your signal even when off or if the battery goes weak.The Sustain Control The 9 O'clock position should be barely noticeable. It will just take out really loud sudden peaks, this is great for protecting your speakers and the like. The 12 O'clock position provides the right presence for using the Keeley compressor pedal continuously while performing. The 3 O'clock position is great for solos. It really adds some cool effects to your playing dynamics. Only when really cranked do you get the pluck sound of your pick emphasized.Tone-tested components The Keeley compressor effect has nothing but tone-tested components and has true bypass switching. Effect switching incorporates a triple pole-double throw switch. You will have clean unaffected sound when in the bypass mode, with an LED for effect indication. Metal film resistors and capacitors ensure the cleanest compressor on the market. Hand matched transistors to less than 1% tolerance ensure you get a perfectly compressed signal, no chance for unwanted distortions. For those wanting a better tone than that of Trey Anastasio from Phish or David Gilmore of Pink Floyd or the Edge of U2 this is it. Power supply The DC jack is the standard type fitting just about every power supply out there. The Voodoo Labs Pedal Power, MXR DC Brick, Boss, Ibanez, etc. power supplies work perfectly with the compressor. ...details
