The MOEN Pretty Dolly Hybrid Analogue Delay features a maximum of 500ms of delay time and can be adjusted using the Time knob. The Blend knob adjusts the level of the delayed return and the Repeat knobs sets the number of repeats of delayed sound. This delay pedal is a hybrid design with analog circuitry to ensure that the frequency response match that of the old-school analog delays which means that you will get that nice warm tone from your delay to sound just like in the good old days. The Pretty Dolly is also a delay pedal with natural echo delay which provides the guitar player with the exact trailing effect of the age old analog delay circuits.
