Penn-Elcom M1500 Double 1/4 Jack Plate

Works great. I installed it in the back of a Fender Mustang 2 amp. One hole is for a 1/4 inch output to another speaker box (dual stack with 12-inch crate speaker and 12 subwoofer speaker) and the other hole has an on/off toggle switch to turn the Fender Mustang 9 inch speaker on or off.

this was a good quality piece, very useful although slightly smaller than i thought...but it worked out nicely, and the price was right. being plastic, it simplifies wiring a 4x12 guitar cabinet as either mono or stereo, or different impedances. highly reccomended, but make sure you measure before buying...like i didn't....the three inch i thought i needed was actually a four inch, which meant i had to glue it on, instead of using screws. still, worth the price!!

Worked perfect for a cabinet build and parallel wiring of 2 inputs. Good quality and easy fit.

does exactly what you need it to. its Small sturdy and recessed. Worked great for a custom guitar cab build

Simply put its a great product for the money. Not a lot I can say about this other than it was perfect for what I needed.

Holes are much larger than 1/4" jack. Sturdy plastic but requires large hole cutout to fit. Not sure I like it but I can make it work. Good price though.

I ordered two of these for some guitar cabinets I'm building, and the holes are a half inch in diameter. I don't know why you would drill a half inch hole for a quarter inch jack, because none of the quarter inch jacks laying around here fit in the hole properly. I'll probably use a spare piece of plastic to cover the holes from the back, and drill my own holes to make it work. I just think it's stupid that it doesn't seem to be sized appropriately to what it advertises. I'll give a second star just because the actual quality is not bad

Works fine, but didn't like the round circle on back it was in the way when I mounted it. I ended up removing it so it had a smooth flat surface on back

Poor quality returned
