• Ebony “butterbean” chin rest 
• Modern equivalent of silk and silver strings (e.g. Vision Stark, Zyex, ProArte) with a loop end period appropriate e-string
• Bridge and nut adjusted for fiddle playing according to customer specs
• Modern keyhole type tailpiece, secured by a real gut cord (in use until the invention of the Sacconi adjuster in the 1950s)
• Hill type fine tuner for the e-string, if desired

Note about bridge and nut adjustment: 

This process is more involved and time consuming than it sounds. With fiddle setup, we are often trying to achieve the sweet spot between a low string height and buzzing that can occur if the strings are set too low. We go through iterations of bridge triming in approximately 1mm increments. We have done so many setups that we can tell when the point has been reached when one more milimeter will make the strings too low.
