Apogee Jam+

I use it to rehearse at home with an iPad (with Bias FX).
Very compact, very good quality.
Sound is OK for the size, price and use case.
The controls are a bit awkward, but one gets used to it.
What I don't like is the location of the ports - headphone and instrument are on the opposite sites and they should go in the same direction - to me! Effectively I am always pulling the one then the other side and it falls of the table. I am planning to buy a short audio angled male to female, just to solve this.

Easy to use, good quality interface. I could not hear a difference to an UA Apollo - x, although i don't use the headphone monitoring directly on the JAM+
The BiasFX package that is included takes a bit getting used to, but it works perfectly fine with Garage band or any other DAW of your choice.

This is simply the best single channel audio interface ever made.
Built like a tank, very simple to use, and with the best pre-amplifier on the market.
It works perfectly on Mac, PC and iOS devices without the need for additional external power supplies.
If you need a single channel sound card, you can't find better.

P.S. It is MADE IN USA.
