Can someone recommend an inexpensive pedal that will allow me to plug an iPod and headphones into it so that I can practice songs that I need to learn? I have a 6 month old son and even practicing with a small amp is often out of the question. Is there anything cheap that will allow me to sound like a bass, and still work on songs quietly? I just want a decent bass sound...I don't need cab options and different amp choices. I would prefer a small footprint too.
