Using this bundle is a breeze. First, connect your instrument to the input of the desired effect unit or amplifier. For the effects like the delay and reverb, you can adjust the knobs to change the intensity and time settings according to your preference. When using the compressor, set it to your desired compression ratio to get a smooth sound. The wah/filter can add a cool funky effect by moving the pedal. As for the amplifiers, make sure to set the gain and volume levels appropriately. When it comes to maintenance, keep the units in a dry and clean place. Wipe them gently with a soft cloth if they get dirty. Avoid exposing them to extreme temperatures or moisture. And always turn them off when not in use to save energy and prolong their lifespan.
