Multi-band compression as last element in the signal chain.
One of the tricks I've tried for making the sound "pop out" more, to make a sound more meaty and less thin, more punch, or what have you... is to use a Multiband Comp as the last element in the chain. It helps a lot for clean sounds. To me, this emulates the sort of thing that happens in a recording/mastering process, but you can take advantage of it live. I've heard a lot of folks diss the use of compression, or recording engineers complain about how everything these days is red-lined to be loud with minimal dynamic range... but I think many people prefer that sound when you do an A/B comparison of the tone with and without the compression. You can make the effect stronger by turning up the level of each of the three frequency ranges. Also, for recordings where you listen to it mostly in a car, that compressed sound is actually easier to listen to that say a good classical recording with huge dynamic range, where you have to keep adjusting the volume for different sections of music.
Edit: Maybe people hesitate to post clips of sounds because they worry about being judged on the quality of their playing or the overall sound. This crowd does get defensive about the product and many people with feel like they are walking up to a firing squad to offer up clips after they presented a judgment about the product's shortcomings. But anyone who is saying something they want to be improved about the sound of a product should absolutely offer up a sound clip or else it's just an unsubstantiated complaint.
