Thank you for viewing. I purchased this item used, but it turned out to be too powerful for my small room in an apartment, so I am selling it to replace it. After purchasing it, I only used it to check if it powered on, and again for this listing. There are no issues with the power. I have not detected any crackling or noise, but please understand that this is based on my subjective assessment as an amateur. Please check the photos for the exterior condition. There is no original box or instruction manual. - Brand: Marshall - Model: MG10CD #Marshall #MG10CD #GuitarAmp I am selling this for a limited time due to a Mercari campaign with reduced shipping costs. If it doesn't sell, I plan to remove the listing.
