I am sure Karn was an influence on Pino, no bad thing obviously, it's how most of us start out, listening to and emulating, to some extent, players who inspire us. I have maybe overstated my case because both Pino and Giblin are superb. I personally prefer Karn but that's down to all sorts of stuff to do with Japan and the times when I was listening to them. Karn seems (to my ears at least) to have developed a very unique style that I cannot hear in anything that precedes him (perfectly happy to be directed to anything that might be an influence on him, apart from Jaco, who I can't stand for more than thirty seconds).
