The magical combination of tremolo and reverb is the earliest example of a perfect guitar effects marriage. First pioneered within historic amplifiers of the 1960's, this amazing combination has made it’s way onto countless records and performances.
Flint gives you the soothing, pulsating, and hypnotic effects that were pioneered in vintage amplifier tremolo circuits, along with three classic and completely unique reverb algorithms. You get the sonically complex ’61 Harmonic Tremolo, the swampy and sultry ’63 Power Tube Tremolo, and the sharp and balanced ’65 Photocell Tremolo. You also get the classic ’60s Spring Tank Reverb, the inventive ’70s Electronic Plate Reverb, and the nostalgic ’80s Hall Rack Reverb.
’61 Harmonic Tremolo is somewhat rare due to its very short period of availability in tube amplifiers in the early 1960s. It gets its signature sound through a dual-band filtering effect that alternately emphasizes low and high frequencies. The end-result is a soothing pulse that has shades of a mild phaser effect combined with tremolo due to the nature of the frequency bands that are alternated.
’63 Power Tube Tremolo utilized the LFO signal to directly influence the power tube bias of the amplifier’s push-pull output stage. The power tubes are biased into lower and higher idle currents, creating the fluctuating gain that produces the tremolo effect. The effects of crossover distortion at low tremolo volumes, increased power tube harmonic distortion at maximum tremolo volumes, as well as the influence of power-supply sag, all add up to the boggy and dirty nature of this tremolo circuit.
’65 Photocell Tremolo is a faithful recreation of the classic photo-trem circuits found in mid-1960s American amplifiers. Those classic circuits used a light-dependent resistor to attenuate the input signal, coupled with a miniature neon bulb that is connected to the LFO. As the LFO oscillates, the bulb gets brighter and dimmer which in turn varies the resistance of the LDR. The varying resistance works with other circuit impedances to change the signal level, which produces a characteristically ‘hard’ sounding tremolo that moves between two levels, reminiscent of a square wave.
