Jeff Roberts Locazite (TM) prototype slide...
Jeff Roberts is a studio and guitar technician for Leo Kottke.
A friend of mine, owns and runs a recording studio here in Viana do Castelo, Portugal, the AMPStudio http://ampstudio.eu/ , so I went to see him and show him my latest buildings. He told me about Jeff Roberts Locazite (TM) slide and showed it to me, one black, the other in brass... while I was trying to play play with the Locazite (TM) slide, he made some recordings with his mobile phone.
