The playing brief
For low tunings, spacious accompaniment or a voice between a standard guitar and bass. The tuning is the first decision; string gauges, scale lengths and the body follow from it.
No. 606 combines a large contrabass-style body with a 700-740 mm fan-fret layout. Its body name does not make it a nylon contrabass guitar.
The desired pitches and string set must be compatible with the scale and setup. The dimensions of No. 606 are an example, not a promise that every tuning will work on that specification.
Longer scales affect the reach of the fretting hand. We consider the neck-body joint, body depth and playing position as well as the low-register brief.
