I really like this pedal, but I'm selling it because I bought a compact tape echo effect. The included accessories are the box and the instruction manual. Thank you. The DTE-1 recreates the sound of the legendary Echoplex tape echo used in the 1950s. However, it doesn't require the maintenance of tapes and heads like the original. The Warble switch simulates pitch fluctuations caused by motor speed variations and tape stretching. The Tone switch allows you to select between a sharp sound simulating a solid-state circuit and a warm sound simulating a vacuum tube circuit. It also features a sound-on-sound function, allowing you to create multi-layered performances with the echo sound as a backing track! It has a maximum delay time of 1.5 seconds and a sound-on-sound function. This is a versatile and fun-to-use effect pedal with a wide range of sound control. 【Controls】 From the top left: MIX Adjusts the mix between the delay sound and the direct sound. Turning it fully to the left results in only the direct sound. Turning it fully to the right results in only the delay sound. At the 12 o'clock position, the delay sound and direct sound are equal. Lo-Fi Adjusts the high frequencies of the delay sound by turning the knob. The high frequencies decrease as the delay repeats. REPEATS Adjusts the number of repeats of the delay. TONE A switch to select between solid-state and vacuum tube simulation. WARBL An ON/OFF switch for the modulation effect. SPEED RANGE Adjusts the delay time using the slider. The delay time is from 0 to 1.5 seconds. SOUND ON SOUND (Footswitch) Allows for 1.5 seconds of recording. The jewel lamp on the left lights up during operation. ECHO (Footswitch) An ON/OFF switch. The jewel lamp on the right lights up in time with the delay time during operation. Top Side, Jacks DC 9V The INPUT for a DC 9V AC adapter. Stereo Out (Dry) Dry OUT for use with two amplifiers. Main Out MIX sound OUT for use with one amplifier, DELAY sound OUT for use with two amplifiers.
