I think it is important to add this note for those who have a Roland JC-120 or JC-77 and remember what their original tank sounded like before it stopped working. Though this reverb tank does work in JC-120s and JC-77s that were made in the 1980's, it does not sound as good as the original tanks. Since I use my 1987 JC-77 much more often than my 1985 JC-120 I put this Accutronics tank in my JC-120 then moved the original tank from my JC-120 to my JC-77. In the near future I will likely get an open side down MOD tank that matches the impedance (probably an 8AB2C1B) then relocate the tank to the bottom of the cabinet in my JC-77. This will require de-soldering the original short reverb tank cables and soldering in longer reverb tank cables that reach the bottom of the cabinet. Also note that you will likely need to fabricate a sort of shelf to mount this tank in place of the original tank. Please see the pic I provided showing the solution I came up with to mount this tank in a JC-77 without drilling into or modifying the amp chassis.
