Smooth Delay SD-1 is a classic delay with applied MAX ANALOG technology. Analog voice circuit (adjustable attenuation of the high and low frequencies) and SMOOTH function enable SD-1 emulate the effect of classic analog and tape echoes. Backlighted foot knobs and TAP TEMPO function enable easy control on the stage. SD-1 can be also controlled via MIDI.

SD-1 is a professional delay type effect with a clickless True Bypass and with possibility to match the effect to the signal level. Input gain signal level regulation avoids distortions and hums, especially at the amp effect loop, where are different signal levels. When the overdriven amp channel is in use connecting SD-1 to amp effect loop brings the best tone. SD-1 can be connected to the serial or parallel effect loop (using KILL DRY function).

SD-1 features two modes of SWITCHING OFF the effect. In HARD mode the switching off is immediate with muting of repeats. In SOFT mode the repeats of previously played tones will resound to the end.

Two ranges of delay TIME setting: from 50 ms to 640 ms and from 100 ms to 1280 ms.
