Using the Peavey Invective MH Mini Amp Head is easy. First, connect your guitar to the input of the amp. If you're using pedals, connect them in the right order between your guitar and the amp. For a clean sound, use the clean channel and adjust the volume and tone knobs to your liking. When you want that high - gain hard - rock sound, switch to the high - gain channel. Remember to keep the amp in a dry and cool place to avoid any damage. Also, make sure to use the right power supply. Regularly check the cables for any signs of wear and tear. If you're not using the amp for a long time, unplug it to save energy and prevent potential electrical issues.
