Using your Bad Cat Black Cat 1x12 Extension Cabinet is easy. First, make sure your guitar amp is turned off. Then, connect your guitar amp to the cabinet using the appropriate cables. Once connected, you can turn on your amp and start playing. You'll notice an immediate improvement in your guitar's tone. When it comes to maintenance, keep the cabinet in a dry place to prevent any damage to the wood or the speaker. Avoid exposing it to extreme temperatures or humidity. If the cabinet gets dirty, you can gently wipe it with a soft, dry cloth. For the speaker, don't apply excessive force or let anything sharp come into contact with it. When moving the cabinet, always use the heavy - duty hand - stitched leather handle for a secure grip. That's all you need to know to get the most out of your Bad Cat Black Cat 1x12 Extension Cabinet.
