The BEQ-PB Bass EQ Preamp Pedal is a pedal version of our famous on board Bass EQ. It has active equilization for treble, middle and bass. The treble and bass are both shelving controls with 14dB of boost and cut @ 6dB per octave. The middle control is a peak control with plus and minus 12dB of cut and boost @ 6dB per octave. A gentle slope of 6dB per octave was chosen because the amount of phase shift is greatly reduced and the resulting sound is both more cohesive and natural with very little of the comb filtering that would normally happen with a 12dB per octave approach. The unit also has a master volume control, internal gain trimmer (with up to 9dB of gain), a battery jack usable with any regulated supply (9 to 27 volts), a bypass footswitch and an indicator LED. The unit was first designed in 1981 and was fine tuned with the help of Alfonso Johnson, Bob Glaub and Leland Skylar.

The Uber Driveulator is a much cleaner drive circuit with more headroom and can operate in two modes the Loose mode is similar to the tight mode of the Standard Overdrive but with a bit more headroom and the tight mode which has even more clean headroom and much more output power. The unit has a Drive control that can turn up the gain of the drive circuit 100 times. A very wide range and musical sounding tone control and a volume control to keep the gain under control, can be used as a clean boost. Also included is a trim pot to set the output gain. This unit is True Bypass using an ALCO heavy duty Footswitch.

DRV-2 Uber Driveulator

A hybrid of vintage sound and state-of-the-art quality, the Demeter Tremulator is designed for years of trouble-free operation.Designed to emulate the classic Fender tremolo effect (or vibrato as it is often referred to), the Tremulator features “lopsided” amplitude modulation with a rounded off traingular modulant waveform. Suffice it to say, the Tremulator sounds like the classic effect found on many vintage amps, but with less noise and hum and a greater range of speeds and depths.

TRM-1 Tremulator

The sound of classic studio optical compression of the 60’s and 70’s at your feet! The first compressor pedal not to suck the life out of your tone. Operation is fairly straightforward. There are two inputs on the front side of the unit: a 1/4″ input jack on the right and a 1/4″ output jack on the left with a battery-ground switch on the input jack. There are two controls on the unit: compress and volume, plus a foot switch to bypass the effect, and an LED to indicate effect operation. On the side there is a trim pot to set the overall gain of the unit. Compress affects the amount of gain reduction (compression) of the input signal. Turning this clock wise will give you up to 30dB of gain reduction (depending on input gain).

OptoCompulator

By marrying the classic Fat Control/Midboost with our new Overdrive we have created the ultimate overdrive/distortion pedal. From fat crunch to extra fuzzy to over the top, this pedal does it all. The midboost goes from thin to ballsy, while the overdrive has the ability to go from edgy clean to filthy in germanium mode and edgy to dirty while in silicon mode.

Fat Control: Our classic circuit updated for this pedal. The tone ranges from flat buffer to 12dB of Fat Boost. It is like turning your strat pickup into a P90. The boost frequencies are set to produce maximum sustain.

Overdrive: Our new Overdrive features variable gain control from unity to over 100 times, that output drives our clip generators (silicon or germanium diodes, switchable) for the ultimate in overdrive sound variations. The overdrives controls are gain (drive), a very usable tone control, volume control, and loose/tight switch. Runs off a standard Boss type 9v power supply.
