I commissioned a 1/2 size 5-string bass from a Hungarian luthier on FB, Bango Istvan- it is fully carved,handmade, rounndback, and made to my specs in terms of body shape, color, D neck, and other variables. I think it is a great instrument as does my local NYC luthier, Paul Biase. he said it was well built, with excellent wood choices, and a great timbre. I agree. I paid $3,200 SHIPPED from Hungary. I am quite pleased with the bass, and I’m sure I couldn’t get a bass of this quality commissioned anywhere else at this price. I am sure he would be happy to build you an instrument with similar dimensions to the Contrabassetto, at 1/2 the price.
