The Mod Electronics Reverb Tanks are high quality upgrade units. Some of the major differences between the Mod®s and other reverb tanks are that the Transducers are wired directly to their respective RCA jacks as opposed to current production tanks where Transducers are connected by a detachable plug to their respective RCA jacks. This makes the tanks less receptive to any outside interference. The original Hammond Accutronics tanks from the 1960s were also wired directly to their respective RCA jacks. In addition, very close attention has been paid to the spacing and size of the lamination of the Transducers resulting in a more vintage like tone.

My reverb was not sounding very good so I bought this. I installed it and had screeching feedback when I turned it up past five. I guess that is just a problem you can have. Amplified Parts responded to my problem and said a return could be arranged. I removed the reverb from the cabinet. Fortunately the cables were long enough to connect it outside the cabinet and it sounds much, much better than my old reverb. It’s not an ideal situation but one I can live with.
I haven't used this tank yet but the last one I bought worked great so I am sure there will be no problems with this one. I will continue to purchase parts from AmplifiedParts.
I placed this order on the 4th of December and it arrived in New Zealand 2 weeks later - I'm very impressed with this delivery time. I'm using this reverb spring to build a stand-alone tube reverb unit inside a Fender 15G combo box - no photo's yet sorry. I recommend the parts and service from Amplified Parts and will be shopping again soon.
