JHS Pedals Little Black Amp Box Passive Effects-Loop Volume Utility

Best for

A guitar amplifier with a series effects loop where the player wants lower output volume after driving the preamp section.

Watchouts

Use only at instrument/line level in a series effects loop. Never place it between an amplifier power output and speaker; it is not a load box or speaker attenuator.

Likely add-ons

• compatible power supply or battery
• instrument and patch cables

Verify before buying

• Does the amplifier have a series effects loop?
• Will it be connected only between effects send and return?
• Is a load box required instead for speaker-level attenuation?
