I had a small one one in a car late 80s , it used lots of power, but that could ave been the inbuilt amplifier. I also had a boom box with a 5 band graphic equaliser buit in.

how portable do you need?

You want to build or buy? If you're up to building one, there are all sorts of simple (and some not-so-simple) tone cone control circuits. A good one is the Baxendall tone control circuit. It can be made as either a passive or active circuit. There are also parametric equalizer circuits. Or you could build something based on the Phillips TDA-1524A or the Sanyo LA3600.

How about reusing the 6month 'much to old' smartphone kids are selling for 30$ ?
