I am adding the TBX into all my Strats as it’s magically useful to sharpen the middle pu and soften the bridge pu. The “5” spot is open & “No Load” giving it three uses for the price of one! It arrived in its usual lightning speed and it’s nice to have a place of this calibre in Canada. Very pleased.
