The Gibson Ukulele Banjo is endowed with the same high standards of quality made famous by the Gibson 'Mastertone' instruments and is offered in a range of models and prices to suit your pocket. Power and beauty of tone - accuracy- and dependability almost unbelievable in such an instrument'.So said the catalogue of the pre-thirties and it is still true today although the prices have escalated a little! Gibson made five styles of Ukulele Banjo :- Style UB-1 More of a fun instrument with only a six inch rim but packing a powerful punch for a small instrument. Style UB-2 and STYLE UB-2 De Luxe Generally finished in a light (or dark mahogany) - an excellent instrument powerful and pleasing - often called the 'Baby' Gibson. Style UB-3 Some confusion here - See page from catalogue below, the instrument has a flat back but on the right the UB-3 shown has a flange resonator fitted.Style UB-4 Again below is when the UB-4 had just been released. Style UB-5 The gold plated version of the UB-4 - only $55 in 1930 - now valued at $5000 - wow!!
