This is the advice you are looking for. I am biased and love my MTD Kinsgton. But that aside, it has hit it's resale floor and it will be an easy way to get your money out again if 5 is not for you. I know we all dream that we will bond with THE ONE but the reality is that what we are looking for changes and not taking a huge 40% hit on money in an instrument is a very good thing.
Preamp yes or no? As soon as the drummer and guitarmageddon kick in, no one is going to be saying "dude, you tone was speaking to me. Your subtle lift at 2Khz let me see into your soul." More bass? Yes. More treble? Yes. Less of both? Yes. I am aware that this is a contentious opinion.
