At the top of the line of the Regal Studio Series Resophonic Guitars, the new and improved RD-40 has been redesigned from the inside out making it the best value when it comes to truly vintage-inspired, professional featured, resophonic instruments available. Using their many years of experience in the development and construction of traditional American acoustic instruments, Regal have also discovered ways to improve upon the most legendary designs from the past without pricing them out of the reach of any level player. Only the finest materials are used to create these new designs that reminisce of the past, while still meeting the demands of today’s modern players. The new body shape takes its cues from instruments of the past; while the real secret to the tone of these instruments lies within. It all starts with a combination of Regal exclusives such as the patented Power Reflex Tone Chamber for added volume, the patented DP-126 Die-cast spider for its bell like response, and a US-made, hand-spun aluminum cone. All together work in perfect harmony to assure the maximum, most articulate tone that can be heard in any playing situation.
