Query: Decent performance, Terrible engineering.

Does it's job, but is put together in a very cheap and shoddy fashion, broke after 3 months of use, im not going to bother re-soldering this thing.Furthermore the layout of the plug creates a nasty mess of wires when you connect your output device to it (i.e. headphones or speakers), and having all that additional weight of the plug and your headphone wires can cause it to fall right out of your guitar when playing.Oh and heres the icing on the cake, unless you remember to register your product you will get 0 customer support, they won't talk to you.All in all total failure.
