Pure Tone Buffer : A big sound from a little box

After plenty of research, I decided I'd need a buffer for my pedalboard. With that much cabling and so many effects some of your signal is lost, and not all of the clarity of your playing comes through. This relatively inexpensive and small (I mean really tiny) box at the start or end of your effects chain solves those problems. As a bass player, this is just fantastic, especially in a live situation, where you want to hold down the groove but still hear all your notes clearly. I can't recommend this enough, and it takes up very little real estate on your board.

Only downside is that it takes a DC 9V, but you can't tell if it's working. An LED would help, but it's all about the tone so it's not essential I guess :)
