Arion Guitar Pedal Digital Delay DDM-1 (60-400ms, 9V DC)

Arion DDM-1 Digital Delay Guitar Effects Pedal (60–400 ms)

The compact Arion DDM-1 Digital Delay guitar effects pedal (a Japanese design by Ueno Kaihatsu Center Ltd.) is designed to create echo effects, lush spatial delay, rhythmic repeats (slapback), and extended sustain when playing electric guitar, bass guitar, or electro-acoustic instruments. The circuit is based on an ADM (Adaptive Delta Modulation) converter with a frequency range of 40 Hz to 7 kHz, giving the repeats a characteristic "warm" vintage color without harsh digital sterility. Delay time is smoothly adjustable from 60 to 400 ms using a two-position range switch (Short / Long) and three control potentiometers.

Key Features and Benefits:

• Two delay operating ranges (60–400 ms): The MODE switch allows you to instantly select between Short mode (60–200 ms — ideal for rockabilly slapback and doubling parts) or Long mode (120–400 ms — for solo parts and ambient soundscapes).
• Precise sound parameter adjustment: Three controls on the top panel allow for flexible adjustment of the dry/wet signal balance (LEVEL), the number of repeats up to self-oscillation (F.BACK), and the exact delay time within the selected range (D.TIME).
• Musical ADM converter (40 Hz – 7 kHz): Proprietary delta modulation gently smooths high frequencies in the delay tails, allowing repeats to sit organically in the mix without interfering with the main guitar part.
• Dual universal power supply (9V battery or power adapter): The pedal operates on either a standard 9-volt battery (6F22 / 006P) or a DC 9V power adapter (100–200 mA, standard 5.5×2.1 mm plug with center negative).
• Convenient indication and battery access: A bright red CHECK LED indicates effect activity and battery level, while the battery compartment cover opens with a press, requiring no screwdriver.

Compatibility and Applications:

The pedal is fully compatible with standard instrument chains and guitar pedalboards:

• Musical instruments: electric guitars, bass guitars, electro-acoustic guitars, synthesizers, and drum machines.
• Connection: standard instrument cables with 6.35 mm (1/4" TS mono) Jack connectors for IN and OUT (to an amplifier, combo amp, effects loop Send/Return, or the next pedal in the chain).
• Power compatibility: standard 9V DC guitar power supplies (Center Negative) such as Boss PSA, Dunlop, Mooer, Joyo, Caline.
