Ok, so disclaimer up front. I was not sure which forum to post this in so, I took my best shot. When playing live, I often find that I have difficulty hearing bass at the expense of vocals, guitars, and drums. So, I was toying with the idea of an in ear monitor system but, the cost about made me pass out. In thinking through this a little further, I have a headphone out on the preamp on my board and was wondering if anyone uses an in ear piece that wireless which just comes off their preamp. It seems too obvious so, there must be a reason this is not such a good idea. But, it seems to me the price would much lower than going with a full blown in ear monitor system. I'd love to hear some thoughts on this and ways that others have addressed the issue. ...thanks in advance.
