Always pay close attention to the series of letters and numbers associated with each reverb tank. In this case 4AB3C1B. If these numbers match your existing tank then this replacement will be compatible. Please refer to our tech corner article explaining reverb tanks for a full explanation of what these numbers signify in terms of compatibility with your amp.

Replaced the stock tank in my B-52 AT-100 which was dead. This one worked great out of the box and fit exactly in the stock location.
