No, you either have LSD or you don't, if it's shitty that could just mean that hits just do not contain high doses and qualitatively speaking there might be impurities that cause more side-effect (the jury is still out on that phenomenon), but other than that LSD is LSD, it is a chemical that is universally the same. Molecules are identical, they are indistinguishable from each other, so a chemical is either that exact chemical, or simply something else altogether.
Low doses can effectively decrease potential for 'advanced' effects like synaesthesia but compensating by taking more hits would fix that. Synaesthesia just isn't that common, well a lot of people have experienced it as some point but I mean relatively you don't get it a lot of the time. I believe it is coupled with intensity but also novelty. My first time on mushrooms I had it, and also my first time on LSD. The more I started tripping the more generic the effects tended to get. But dosing higher brings things to another level and can be like a first time again i.e. the first time (in a long while) to trip that hard.
It's also likely IMO that some people are more sensitive to getting it than others.
A tip I can give is to use nitrous oxide with psychedelics. I've had really sick experiences with that and some of them scared me shitless so let that be a warning, but 2C-X plus nitrous makes for a very good recipe for a number of extra special effects like synaesthesia of a complete and consistent shift in color spectrum exactly like you get by playing with the "hue" option in photoshop.
For example I think it was on 2C-B and nitrous (maybe also bk-MDMA in that mix, not sure - cannabis was likely to be used as well) when I suddenly felt like the color red was drooping over one hemisphere of my brain. I don't mean "something that is red" but rather the pure concept of red-ness.
It's not typical synaesthesia which involves another kind of sensory input that is transformed but I am just giving an example of what kind of totally weird things can happen with nitrous and psychedelics.
