Thanks all.
I've since EQ'd the drums and bass with the PSP Audio EQ bundle that I just purchased. Like the PSP Old Timer compressor (Which I love!), these plug-ins are really well written and even though they are 64-bit, you can put a serious bunch of them in your project with almost no degradation in performance. I haven't reposted this, but I will soon to see what you think of the PSP EQ treatment.
