GHS Boomers are the longstanding and original "Power Strings". Using GHS' Dynamite Alloy these strings pack a bold, POWERful, bright punch while being flexible, soft, and smooth to play thanks to the round core. Halfway between an .010 set and .011 set. Perfect for the player that needs a bit more than the regular lights can offer. • MFSKU GB10.5 • UPC 737681030070
