Mainly because the US versions of the G&L basses are customer built to order, so you don't see them hanging on walls waiting for someone to buy it. It's only the Tribute basses which are sold off the rack so to speak. G&L has their own special niche of the market.What do you guys think prevents the G&L from being as classic and widely used as the other 3? They're well regarded and praised often, yet, I rarely see them out in the wild.
