DESIGNED BY SYNTH PIONEER TOM OBERHEIM

The Maestro FSH-1, also known as the Filter Sample/Hold, was an innovative pedal released in the late 1960s. This pedal produced unpredictable filter sweeps and sample/hold effects, making it ideal for experimental and psychedelic guitarists. Its scarcity and unique sound have made it highly sought-after among collectors and sonic explorers.

The sample/hold settings allow players to add rhythmic patterns to their playing far beyond the typical vibrato and tremolo. The filter is classic low pass and sounds incredibly smooth. Controls allow you to tweak the rate of the sample/hold as well as the frequency of the filter. This is truly a fantastic pedal.

 

The controls

Filter Range: Probably the width of range in which the filter moves. Could also be a fixed width with knob controlling the center frequency (high/low) of that range.

 

Filter/Sample/Hold: Switches the effect to envelope filter or sample/hold.

 

S/H Speed: Controls the speed of the sample/hold effect.

 

The controls consist of knobs for range (depth) and sample/hold speed. A switch that engages either the sample/hold random filter effect or an envelope follower for a unique auto wah sound.

The Maestro Invader Distortion is a high-gain, all-analog modern distortion pedal with a heavy, aggressive, dominant sonic character and loads of rich harmonics. With the Maestro Invader Distortion, users can generate a wide range of distorted sounds. The 3-knob control layout gives users intuitive control over Gain (distortion amount), Tone, and output Level, with more than enough volume on tap to easily exceed unity gain when you want to. Users can also engage a built-in noise gate with the top panel toggle switch. An internal trim pot mounted on the circuit board inside the pedal allows the user to adjust the level of the noise gate's Threshold.

Das Maestro Discoverer Delay ist ein modernes Analog-Delay-Pedal, das die legendäre analoge Bucket-Brigade-Technologie (BBD) nutzt, um klassische, warme und ansprechende Delay-Sounds zu erzeugen. Die intuitive Bedienung mit drei Reglern ermöglicht es dem Benutzer, die Delay-Zeit (von 20 ms bis 600 ms), die Anzahl der Wiederholungen (Sustain) und den Pegel des Delays im Mix schnell einzustellen. Ein Kippschalter aktiviert die integrierte Modulation, die dem verzögerten Signal Effekte von einem leicht gesättigten, bandähnlichen Wow- und Flutter-Effekt bis hin zu einem stark tonhöhenverschobenen Modulationseffekt hinzufügt. Zwei interne Trimmpotis ermöglichen die Einstellung der Rate (Geschwindigkeit) und der Breite (Sweep-Bereich) der Modulation. Der True-Bypass-Fußschalter aktiviert die LED-Leuchten in den Trompeten des Maestro-Logos, sodass Sie immer wissen, wann der Effekt aktiv ist.

The Maestro Discoverer Delay is a modern analog delay pedal that proudly utilizes legendary analog bucket brigade device (BBD) technology to deliver classic, warm, and inviting delay sounds. The intuitive 3-knob control layout lets users quickly dial up the length of the Delay time (with a range from 20 ms to 600 ms), the amount of Sustain (delay repeats), and adjust the level of the delays in the Mix. A toggle switch engages built-in modulation that applies anything from a slightly saturated, tape-like wow and flutter effect to a heavily pitch-shifted modulation effect to the delayed signal. Two internal trim pots allow the user to adjust the Rate (speed) and Width (sweep range) of the modulation. The true bypass footswitch triggers the LED lights in the bugles in the Maestro logo when it’s on, so you’ll always know when the effect is active.

The Maestro Ring Modulator RM-1A is a pioneering guitar effects pedal designed by Tom Oberheim in 1972, renowned for its unique sound-shaping capabilities. It produces complex, dissonant tones by mathematically combining input signals, resulting in metallic, robotic, and sci-fi-like sounds that are not harmonically related to the original input. The RM-1A was one of the first effects pedals aimed at keyboardists and gained popularity among innovative musicians of the era, including Herbie Hancock and Joe Zawinul. Its versatility allows for a wide range of effects, from clangy robot noises to swirly tremolo and even extreme distortion. The pedal's historical significance lies in its role in shaping the experimental sound of late 1960s and early 1970s music, marking an important development in electronic music and effects processing.
