This instrument, usually know as The Beast, was one of my better finds and is often admired for both looks and sound.
I discovered it a few years back at a local flea market and got it for a very small price.
It came to me as an unfinished home made project with neither bridge, saddles or frets although everything else was there including the highly decorative tailpiece. I set about to make bridge and saddles and started to price fret-wire, as the fret slots had been cut, then realised that this would be the perfect project to try as  fretless. With the slots being cut it provided markers for fingering so all I had to do was dress the edges of the cuts and it was good to go.
This is a full size acoustic bass with a 33 ½ inch scale and a 5 inch deep body. I include a picture of it alongside a standard dreadnought body acoustic guitar, for comparison.
The back, sides and neck are solid mahogany with a rosewood fingerboard. The top is solid wood, no laminates, but I really don’t know what timber it is.
Strung with standard bass guitar strings it gives a very pleasant natural tone and substantial volume. I usually record it with the Se-x1 medium diaphragm condenser microphone at close proximity (6 – 8 inches) and process the resulting signal with only a slight EQ setting to eliminate any background hum and roll off the treble end.
