The world's first steel-string guitar with patented Lens Resonance System® technology has arrived on the market! The Riento Acoustic D-Series line includes the DLT (Luthier Top) and DS (Standard) models. The DLT model features a soundboard handcrafted by Ville-Veikko Ponkiniemi in Tampere, and the instruments are built in the EU. The LRS system has over 25 years of experience in classical C-models, and its adapted version works exceptionally well on steel-string guitars too.
