I used this to replace a broken "high" input on my Aria Pro II AB-50 Bass Amp, which coincidentally uses the same form of jack as this genuine Fender part. It fit and works perfectly, as expected. At the end of the day, this is simply a new mono socket jack for an amplifier.
The part came in a plastic bag alongside all the fittings necessary for the majority of amps that would use such a format of mono socket. I have no complaints with the quality of it either. It is absolutely a huge improvement from the original "dengkai" sockets originally on the amp I was replacing.
My only complaint is that the price is rather steep for such a part, but that's more down to Fender than anything else. I would recommend this in general however.
