This is the kind of song that NEEDS a signature lick, a melodic hook..... something that repeats in places to grab the listener and make them want to listen. Think of Carlos Santana and Europa.
The tone on the guitar is smoking sweet!! Love that, but the song and the guitar just seems to wander aimlessly and as a result, since there is no hook to grab on and pull it all together, an the average listener will lose interest after a minute or two not hearing anything repeated as a hook.
Here is a link to a song I did using BB and it has a melodic hook in it.
