Featuring a "4C Hammond Reverb tank." Huh.

I suppose it’s fitting that an amp with so many knobs and sliders has an ad with this many bullet points. Now, here’s some Carvin trivia straight outta Wikipedia:

The company was founded in Southern California in 1946 as the L. C. Kiesel Company. As of 1947, the company was manufacturing steel guitars in Gothenburg, Nebraska. Around 1948, it returned to Southern California where the company name was changed to Carvin, from Kiesel’s two eldest sons, Carson and Gavin.

Steel guitars? Gothenburg, Nebraska? Wow.
