that's the thing, the jb3 is not a tank. it wasn't designed for taping. it's a consumer-level piece of equipment and you know it just by the feel. that said, i never got to use the one i bought, returned it, and picked up a d8 instead.
the incredible benefits of the jb3 cannot be overlooked - they're huge - but there certainly are some drawbacks.
i went with dat and would do it again.
