What is Joe Satriani doing at 0:55 onwards in "Searching" from "Is There Love In Space" in order to achieve the sounds he is making?
My first instinct is that it sounds like a synth with a glissando 'lock' turned on, where one would hold a note and then tap other notes and the syth will glissando between the notes... Is that what is happening here or is Joe doing something awesome with the guitar to get the same effect?
