Product Information

Full details

The EHX Memory Boy is an analog delay effects pedal designed for musicians seeking warm, classic delay and modulation sounds at an accessible price. It builds upon the heritage of the Deluxe Memory Man, offering up to 550ms of analog delay, switchable chorus or vibrato modulation, and the unique ability to control delay time or modulation rate with an external expression pedal. While it delivers rich, musical tones, users should be aware that it does not feature digital pristine delay sounds and requires a compatible power supply.

Extended Product Information

FAQs

What is the maximum delay time on the Memory Boy?

The Memory Boy offers up to 550 milliseconds (0.55 seconds) of analog delay time.

Can I use the Memory Boy with bass guitar?

Yes, the Memory Boy is suitable for bass guitar, providing warm analog delays and modulation effects that can complement bass tones.

Does the Memory Boy have tap tempo?

No, the EHX Memory Boy does not feature a tap tempo function for setting delay times.

What type of modulation effects are available?

You can select between Chorus and Vibrato modulation effects. Additionally, you can choose between triangle and square waveforms for these modulations.

Can I power the Memory Boy with a standard 9V center-negative power supply?

While it requires 9V DC and a center-negative plug, the Memory Boy specifically needs a 9.6V power supply with at least 100mA. It's best to use the included EHX power adapter or a compatible replacement to avoid damage.

What does the Expression Pedal input do?

The EXP PEDAL input allows you to connect an external expression pedal to control either the Delay Time or the Modulation Rate in real-time, offering dynamic sound manipulation.

Is the Memory Boy a digital or analog delay pedal?

The EHX Memory Boy is an all-analog delay pedal, designed to produce warm, vintage-style delay tones.

Troubleshooting

No sound or weak signal

Check all cable connections (instrument in, output out). Ensure the pedal is powered on and the correct power supply is used. Verify the effect is engaged (LED is lit).

Hum or excessive noise

Ensure you are using the correct, EHX-provided power supply. Try plugging the power supply into a different outlet. Check for noisy cables or other pedals in your signal chain that might be causing interference.

Modulation effect is not working

Ensure the 'MOD' knob is turned up and the 'CHORUS/VIBRATO' switch is set to your desired mode. Check the 'WAVEFORM' switch. If using an expression pedal, ensure it's correctly connected and configured to control modulation if intended.

Expression pedal is not controlling the effect

Verify the expression pedal is compatible and correctly connected with a stereo cable. Check the internal DIP switch setting to ensure it's set to control either Delay Time or Modulation Rate as desired.

Pros and Cons

Pros

  • Authentic warm analog delay tone.
  • Versatile modulation options (Chorus/Vibrato).
  • External expression pedal control for dynamic sound shaping.
  • Affordable entry into classic analog delay sounds.
  • Durable construction suitable for stage use.

Cons

  • Delay repeats can degrade in tone with heavy feedback settings, characteristic of analog delays.
  • Maximum delay time (550ms) may be limiting for very long ambient delays.
  • Requires a specific power supply (included), not compatible with all standard pedalboard power bricks.
  • No tap tempo functionality.
  • Modulation can be quite noticeable and may not suit all musical styles.

Setup, Compatibility & Care

Setup:

  1. Connect your instrument (guitar, bass, etc.) to the INPUT jack using a standard 1/4" instrument cable.
  2. Connect the OUTPUT jack to your amplifier or the next pedal in your signal chain using another 1/4" instrument cable.
  3. Connect the included power adapter to the DC power input on the pedal and to a suitable power outlet.
  4. For expression pedal control, connect a compatible expression pedal (e.g., EHX Expression Pedal) to the EXP PEDAL jack using a stereo 1/4" cable. Use the internal DIP switch to select control over Delay Time or Modulation Rate.

Compatibility:

  • Power: The Memory Boy requires a 9.6-Volt DC power supply with a minimum current of 100mA. The center conductor must be negative. Using an incorrect power supply may damage the unit. The included EHX9.6DC-200 power adapter is recommended.
  • Expression Pedal: Compatible with standard expression pedals that send a variable resistance signal.
  • Instruments: Suitable for electric guitar, bass guitar, keyboards, and other line-level instruments.

Care:

  • Keep the pedal clean and dry. Wipe with a soft, dry cloth. Avoid abrasive cleaners.
  • Protect from extreme temperatures and moisture.
  • Ensure cables are securely plugged in but do not yank them forcefully.
  • Avoid placing heavy objects on the pedal.
