I have a Roccaforte Custom 80 coming and it most feedback I read states the master volume doesn't work well because of the linear taper pot. The builders description says "The master volume, if used, is for darkening the tone and adding a little dirt at lower volume settings." Seems like the MV doesn't work on the traditional sense. Will changing this pot to an audio taper make the master more usable and what affect might it have on the tone, if any? My Splawn works the same way in that the volume is tricky to set a decent level, something that he fixed on later models.
