Sometimes it takes more work to get the product you are looking for. But when you are deciding on a price, the first and foremost thing is "What is it worth to the customers?" If ZomBass can be bought cheaper and gives you more, then people are going to go with that, most likely. Just because you say you put more work into it, doesn't mean you can sell it at a higher price. Rule number 1, think of the customers, not yourself. Don't get me wrong, I don't mean disrespect in any way, just some constructive criticism ,and only to help guide you in the right direction, because as far as i know, you are pretty young and i would assume are probably newish to selling a product. However, the samples sound pretty good to me, I like the grindy tones, being a sucker for grindy bass. I also like that you sampled all the notes down to E1 (which as far as i know is an octave below E standard on a 4 string bass?). But me personally, I would rather buy Zombass considering your price tag. If I were to put the price tag on it, comparing it with the other product, I would pay 20 bucks for this. And that's only because it does in fact include the pre-processed tones, although I would not use them in my own mixes, maybe for jamming or just tracking. Also, I would consider redoing the demo on the site, as the way you present the tones comes off a little unprofessional. Anyways, best of luck with your product.
