    Last fall during Covid, I bought a 5 watt amp kit from Parts Express for $9.00. I made a plywood cabinet for it and used an 8 inch speaker that came out of another amp. I adapted it to run on 8 D cell batteries. Wow! It works great as a low power guitar amp when playing with 3 or 4 other people.

    This spring I wanted to make a lightweight, battery powered bass amp.
    So, I bought another of the $9.00 amps. This time I used a reinforced cardboard box for the case. It has multiple layers of cardboard glued into the inside. That stiffened it up enough so it doesn't rattle and produces a nice tone. It has a supposed 12 inch bass speaker that I bought on eBay, and I also adapted it to run on 8 D cell batteries. IT ONLY WEIGHS 11 POUNDS! It works well with 3 or 4 acoustic musicians that I play with. The entire project cost me less than $50. I think it sounds as good as my Pignose Hog 30 amp that I paid much more than $50. for. 8D5FF33F-79AB-443E-BC27-C9059B401EEE.jpeg A7F5CA37-CCC1-468A-887B-FAA2F10FD08B.jpeg E9938CB3-F9C8-456C-B096-9B6F476D5A0B.jpeg

    Having played the Pignose at my local shop, I would tend to agree, even though I haven't heard your corrugated cab. It would be diffucult for it to sound worse.
