Introducing the COMP-2 Compulator Pro. This high quality optical compressor gives you the magical sound of LA-2A type compression in a compact but powerful package. Using the same circuitry as our Compulator pedal, the Compulator Pro adds attack & release controls, which can be tweaked to modify the onset & sustain of the compressor. You can finely tune your compressed tone to mimic almost any type of compressor (with the controls set at their fastest setting you have the same setting as our classic Compulator). We have also included a adjustable gain boost when you want deep compression at the flip of a switch or if you need to set up for two different instruments. Hand made in the U.S.A. using the highest quality components.

COMP-2 Compulator Pro

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).

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.

BEQ-PB Bass EQ Üreamp

Introducing the FZO-1 Fuzzy Octavulator. Get the classic octave tone of the sixties without the noise and instability. Our octave up is coupled with the killer tones of our Fuzzulator pedal, giving you a combination that guarantees some totally amazing sounds. Using a completely new analog circuit to generate the octave sound we have eliminated the problems found in the older designs of our competitors. It delivers a smooth, musical and usable sound through a much greater harmonic range. Like all Demeter pedals we take classic pedal concepts and redesign them to make them perfect. The unit has controls for Fuzz, Volume and Tone, as well as a Tight and Loose switch. Both the Fuzz and Octave effects can be used either in combination or independently of each other
