6 string acoustic basses are quite rare animals so it was great to get two orders to work on together. Both share many features (sitka spruce top, ebony fingerboard, flamed maple binding, RMC saddles and preamp, Schaller 2000 series gold machines with ebony buttons and carbon fibre reinforced maple and walnut laminated necks to name most of them.) But let's look at them individually.
Back and sides are of Irish walnut which is a very difficult wood to source. It is also used for the solid rosette and headstock veneer. There are 20 full width Fender bass type frets with a small 21st fret on the fingerboard extension which works for the top two strings. The RMC saddles and preamp coupled with Thomastik Acousticore strings give the best acoustic bass sound I have ever heard and this combination does not fail in the fretted situation. These strings have a nylon core with bronze windings and so have very low tension which does reduce the acoustic output compared to regular acoustic bronze strings but this sort of instrument would seldom be used in a purely acoustic situation anyway so this is not a disadvantage. Regular strings could be fitted if more volume was required.
The back is rather pretty and you can just see where the customer had his signature inlaid in ebony on the back of the headstock.
Sapele this time for the back, sides, rosette and headstock of the fretless. The fingerboard has 24 fret marks inlaid in maple on the upper edge so they are visible to the player but not on the face. RMC+Acousticore+ fretless = very realistic double bass sounds with plenty of growl if required. The subtle nature of the RMC tone control gives a wider tonal range than might be expected.
Another view which shows the warm colour and figuring of the sapele.
