So this weekend after getting some really decent practice time in, I decided to nail a song that I had been trying for a while. Painkiller from Judas Priest. I love this song because it's fast and packs a lot of punch.
The section that I was struggling with was at about 1.22. I had the basics right, but I was NO WHERE near being close to the pace of the actual track. So I pulled out my trusty speed trainer and went to town. 2 hours later and I had it up to about 210 bpm and was making each note nice and clean.
I know it's not for all, but this has SERIOUSLY helped me and may help a few others...........they have a trial version that's free by the way.
Anyone in here use it?
