How do I connect the amplifier to a speaker cabinet?
Use a speaker cable (not an instrument cable) to connect the amplifier's speaker output to your cabinet. Match the impedance selector (4, 8, or 16 ohms) to your cabinet's impedance. Never operate without a load.
What is the power output of the Classic 20 Mini Head?
It delivers 20 watts of all-tube power, suitable for small to medium venues or home practice.
Does this amplifier have an effects loop?
Yes, it includes a series effects loop with Send and Return jacks for connecting external effects processors.
How do I replace the tubes?
Turn off and unplug the amplifier. Let it cool for 15 minutes. Remove the tube cage, gently pull out old tubes, and insert new ones of the same type. Re-bias if necessary (recommended by a technician).
What cleaning methods are safe for the amplifier?
Use a dry, soft cloth to wipe the exterior. Avoid water, solvents, or abrasive cleaners. For grilles, use a vacuum with a brush attachment.
Can I use the amplifier with a different voltage?
Yes, the power supply is voltage selectable (120V or 240V) via a switch on the back panel. Ensure the voltage matches your local mains before powering on.
Does the Classic 20 Mini Head have a built-in reverb?
Yes, it features a spring reverb with a dedicated Reverb control knob.
What is the Boost function?
The Boost switch adds extra gain and volume, pushing the amplifier into higher saturation for lead solos or heavier tones.
How should I store the amplifier when not in use?
Store in a dry, cool place away from direct sunlight and extreme temperatures. Cover to protect from dust. Remove the power cord if storing for long periods.
