Woof dude this turned out real good. I especially like the basstone now, it's real damn good.

I would like to echo the sentiments of Renard in your determination. It certainly comes across in how hard you worked on this piece. And sonically it shows, especially if compared to some of your previously submitted tracks. This seems like one of your most developed and versatile tracks.

I can't wait to see what else you cook up :D

At the very least you deserve recognition for how determined you are to improve. Congrats on your persistance. Keep it up like this and you'll be going places fast.
This track is 100x better than the original you showed me back at the start. The guitar is much fuller sounding. You're using some more realistic sounding parts now, too.

Sampled guitars, to me, will never match a recorded guitar. The main reason is that they're too perfect and remain on pitch whereas a real guitar string changes pitch over time, higher when you hit it and lower as the vibrations slow, and the pitch can change depending how hard you're pressing the string, too! So if you're excited and playing energetically, you tend to sound a bit sharp.

Having said that, this track has a good sounding bass and a decent drum sound and you've made it enjoyable to listen to. Maybe in future you could try adding some strings or a string pad to fill in the silence and help hide some imperfections in your virtual instruments?

You asked specifically about the shredding part and I'd say that's the most realistic part of the track. Approved! Hehe

Good work on this one, keep it up!
