I have a 200 watt 2x10 ampeg combo, and I really want some crunchy mid/highs. The combo has a very punchy, tight low end, but a rather un-defined high end. So I'm thinking, could I just run the highs into a cheap 1x10 guitar amp? I think this would be the best, cheapest way to distort my highs, too. What's a good combo for this? I'm thinking some random Fender or Crate guitar amp would do, unless there is something better for the price (I have about $50 to spend). Would it even be practical?
