Let me start by saying I don't know what sets the TV apart from other juniors. I do know that the junior was created with budget in mind, hence no binding, single pickups, etc. In most cases, it came with a P-90 and was found to be a real players guitar in its own right.
Any of this I know only from browsing Les Paul forums. I'm seriously thinking about jumping on a new Les Paul Jr Lite double cutaway. Perhaps as early as tomorrow.
