Carefully unpack the BOSS ME-90, ensuring all components are present: the unit itself, an AC adapter, and potentially a product registration card. Before connecting, visually inspect for any shipping damage. Connect the included AC adapter to the DC IN jack on the rear panel and a suitable power outlet.

Initially, connect your guitar to the INPUT jack and your amplifier or interface to the OUTPUT jack. Ensure all connections are secure. The ME-90 is now ready for basic operation and further setup through the manual or BOSS Tone Studio.

Powering On and Basic Operation

To power on the BOSS ME-90, press the POWER button located on the rear panel. The unit will initialize, displaying the BOSS logo. Use the footswitches to navigate through preset patches in Memory mode. Holding the MEMORY/MANUAL footswitch activates the built-in tuner.

Adjust the volume using the master volume knob. Experiment with the pedal effects by engaging and disengaging them with the dedicated footswitches. Explore the initial sounds and familiarize yourself with the basic layout.

Understanding the Foot Switches

The BOSS ME-90 features multiple foot switches for versatile control. The MEMORY/MANUAL switch toggles between preset recall and direct effect control. Dedicated footswitches activate/deactivate each effect category – Pedal FX, Modulation, Delay, and Ambience.

These allow instant on/off access to sounds. The expression pedal controls parameters like wah or volume. Utilize these switches to seamlessly transition between patches and sculpt your tone in real-time during performance.

ME-90 Panel Overview

The ME-90’s panel organizes effects into sections: Pedal FX, Modulation, Delay, Ambience, Compressor/Limiter, and Booster.
Input/Output jacks and controls manage signal flow and connectivity for diverse setups.

Pedal FX Section

The Pedal FX section houses core guitar effects like overdrive, distortion, fuzz, and boost.
These effects emulate classic stompboxes, offering a wide range of tonal shaping options.
Adjust parameters like Drive, Level, and Tone to sculpt your sound.

The section features a virtual pedalboard layout, allowing you to chain effects for complex tones.
The PEDAL FX knob controls the selected effect’s intensity, and the expression pedal can be assigned for real-time control.
Experiment with different combinations to discover unique sounds.

Modulation Section

The Modulation section provides essential effects like chorus, flanger, phaser, tremolo, and rotary. These effects add movement and texture to your guitar signal, enhancing its depth and character. Each effect offers adjustable parameters such as Rate, Depth, and Feedback.

Experiment with subtle chorus for thickening or dramatic flanging for swirling sounds. The ME-90’s modulation section allows for creative sound design, offering a versatile palette for diverse musical styles.

Delay Section

The Delay section within the ME-90 offers a wide range of delay types, including Standard, Analog, Tape, and Modulation delay. These effects create echoes and repetitions, adding space and dimension to your sound. Key parameters include Time, Feedback, and Level, allowing precise control over the delay characteristics.

Adjust parameters like Rate, Depth, and Feedback to sculpt the ambience to your liking. Create subtle shimmering choruses or swirling, psychedelic phasers with ease.

Compressor/Limiter Section

The Compressor/Limiter section on the ME-90 offers dynamic control, essential for evening out volume levels and adding sustain. Compression reduces the dynamic range, making quiet signals louder and loud signals quieter, resulting in a more consistent output.

The limiter prevents signals from exceeding a set threshold, protecting your amplifier and ensuring a clean, distortion-free sound. Adjust Sustain, Attack, and Level to tailor the compression to your playing style.

Booster Section

The Booster section provides a clean volume boost, ideal for solos or adding punch to your overall sound. It’s a simple yet effective tool for increasing your signal level without altering the tonal characteristics of your guitar or effects chain.

Adjust the Level knob to control the amount of boost applied. This section can be used subtly to enhance your existing tone or aggressively for a significant volume jump. Experiment to find the sweet spot for your needs!

Input/Output Jacks and Controls

The ME-90 features a standard ¼-inch Input jack for connecting your guitar, and dual ¼-inch Output jacks for stereo operation or connecting to an amplifier and a mixer. An Aux Input allows for playing along with external audio sources.

The Control knobs adjust various parameters, while the Expression Pedal jack enables real-time control over effects. Carefully review the panel layout for precise functionality and optimal signal routing.
