Rejuvenate Your Acoustic Tone with TUSQ Bridge Pins Are you looking for a simple and inexpensive way to extract maximum tone out of your acoustic guitar? Of course you are. We have three words for you: TUSQ bridge pins. Graph Tech TUSQ bridge pins will ensure that all the vibrational energy from your strings is getting to your guitar's body and top, giving you singing highs, powerful lows, and rich harmonic overtones. All that from a set of bridge pins, you ask? Yep. You see, bone and ivory pins, being organic, can have dead spots, which result in inconsistent transfer of this energy. Top guitar manufacturers use TUSQ bridge pins, nuts, and bridge saddles on their instruments. And if you, like Sweetwater players, are seeking maximum tone and output from your instrument, you should too.
