Sounds pretty damn close to my original, vintage 1965 Super Reverb tank.

I purchased this tank after pulling my old Accutronics tank out of my 1981 Princeton Reverb amp and ID'ing the serial number, etc. to insure that I bought the correct tank. I'm not an electrician or even a hobbyist, but I purchased a multimeter first (Klein Tools unit) and lent my hand at determining if the input/output jacks and transducers were bad on the old tank (I saw this on YouTube videos). After monkeying around and getting readings all over the place each time I tried, I said the heck with it and just purchased the new tank. On the advice of my son, I added new RCA cables to the purchase. Glad I did. When I installed the new tank, I plugged into the old cables. Nada. Zip. Muerto. So I plugged it up with the new cables and that sweet little amp pushed tone out comparable to me playing it in Winchester Cathedral! Word of advice, you'll need the cardboard base plate from the old tank so don't throw that away. This replacement comes with an open bottom. Also, as another reviewer wrote earlier, don't pay attention to the color of the input and output jacks on the new tank. Be sure you plug amp input to tank input and amp output to tank output, regardless of the jack colors on the tank. You will see input and output stamped on the side of the tank. PS, this new tank was stamped with both Accutronics and Belton. I give it four stars because I only played through the tank a few times so far. I'll likely revisit the review in a year. PSS I plugged up the old tank with the new cables and it worked! Comparably, to me the new tank has more depth and reverb tone per dial setting than the old tank. I cleaned up the inside of the amp, Armor-all'ed the tank bag and installed the new tank. I put the old tank in storage. Rock on, Garth.

I bought this to replace the crappy, short, 3 spring box that was stock in my 1980 Princeton Reverb ii (that I gutted rewired into a BF deluxe reverb). The quality is outstanding - nice solid RCA jacks - excellent BF tone.

These are the tanks for many old Fender tube amps where the pan is mounted on the bottom of your combo cabinet.Be aware that you'll see Belton for sale, and Accutronics for sale... the are the same pan! Accutronics is priced about $7-10 more, but you'll get the same product. The tag says Accutronics Belton. Whichever you buy, you'll get the same. Might want to go with the identical product for less money.

Very impressed with the quality of the tank. Don't know if it is, sound wise, better or worse than others but it sounds good to me. It was used to replace a broken tank in a Fender amp.
