I would class myself as a beginner guitarist - I've been learning for about 9 months. I've always wanted to play blues guitar and although I've had regular guitar lessons I haven't tried any DVD-based lessons, so I thought I'd try this.
It started off pretty easy with the E minor pentatonic and blues scales, then moved onto a few licks. These however needed quite a bit more practice until I became proficient, but I found the lessons valuable - in fact I'm going to other the other discs in the series :)
Just one complaint about the lessons. Steve Trovato plays each scale or lick at either a slow pace or against a backing track (included on the DVD). However, there is no use of a metronome which would allow you to progress steadily up to full speed - for me, this would have been a major improvement. I also have to say that for me there wasn't a full week's worth of material here - perhaps the later discs will prove more challenging.
For now, I'll give week 1 of this series 3/5 stars.
