Offering complete tonal balance from top to bottom, this attack-sensitive and powerful 12 inch model was co-developed with veteran session and touring pro Paul Franklin. With headroom to spare, the PF-350?s tone transfers from low volume to very loud with warmth and clarity, making it ideal for pedal steelers and 6-stringers alike.
