In his newest model, Thomas Ochs combines the advantages of his model „Kasha“ (clarity, brilliance, fundamental bass, sustain, balance in all registers and chords) with the advantages of the so called “Double-Top” construction. Double-top, „sandwich-top“ or „composite-top construction means a special method in which the guitar’s top is laminated from several layers in order to obtain the lowest possible weight while at the same time having very good acoustic characteristics. The best-known method is the one developed by Matthias Dammann and Gernot Wagner in the 1990’s which is a laminate of two very thin (tone)wood layers with a middle layer of meta-aramid material (Nomex). Instruments in double-top construction is attested a higher sound intensity with easy playability and excellent response. So dynamic playing becomes a pleasure with a treble that has no equal.
