Many of you will have seen this legendary video with Christian McBride and his trio a few years back on Fried Pies. It's a sublime video with showcasing the trio's dazzling virtuosity, while still sounding sincere and having an amazing feel to it. I've been transcribing McBride's bass solo. However, I've been unable to replicate a certain technique where he alternates between a C and Eb at about 3:47. Of course, this structurally simple line sounds very much like a line that originated on blues piano. Unfortunately, the video cuts away from McBride at the moment he plays the line. I've been trying to replicate the line myself to no avail. I have experimented with a few different hammer on and pull off approaches with my left hand, but nothing seems to get sufficient sustain to keep the line going. I might be wrong, but I'm pretty sure it is the left hand dictating the shape of the line. Would anyone know a technique that could get that sound at 3:47 out of my bass? It would be greatly appreciated!
