Hey, this is far from bad!
You’re basically a RDT DSX/DBX, very similar to what I do . So you should start with that:
Try doing a tremolo at medium-high speed and try to always internalize the same motion. This motion, which you feel flows better, smoother, and more consistently, should be your main one and occasionally your most confidence.
It doesn’t matter if your single-string tremolo has a single escape or trapped, what matters is that you need to apply this main motion whenever you want with the same consistency.
I don’t recommend practicing burst because it won’t give you the true sensation of playing fast and consistently.
Just because you have an RDT DSX/DBX form doesn’t mean you can’t do USX. Some of these licks you’re trying will work better if you just do a sequence of different escapes (USX), like the first lick and the other, which I think is Shawn Lane’s 5s at the end of the video.
This specific lick will work best if you do four USXs and one DSX, immediately returning to USX. Then just repeat the sequence, and you’ll notice that you only need to worry about one “complex” string change. Once you apply this at a slightly higher speed, this will decrease.
You could start with an upstroke to do most of the DSX, but the furthest string change would be inside. Although it’s easier than outside, the error rate is higher when it comes to stringskipping, especially with one note per string at the end of the lick. That’s why outside is a bit more reliable for medium and long stringskipping.
But to be honest, if you can do a TC with us, it will be even easier for us to answer your questions, and of course, we’ll be happy to help you in any way.
If you’re interested, just open one on the platform and we’ll take a look.
