Harby Pedals Noble Tone Overdrive
Just Like the Original
The Noble Tone, like the Prince of Tone, has two internal DIP switches, which add some subtlety to the knob settings and modes. Our pedal also employs the internal treble trimpot to add high-end, as well as the JRC4580D IC (integrated circuit) New Japan Radio, Co., Ltd. chip.
The MA856 silicon through-hole clipping diodes found in the original Prince of Tone are no longer available or in production. So we use the closest diode currently available for the Noble Tone, the BAS33 silicon through-hole clipping diode. Like the MA856, the BAS33 clips at approximately 0.82v. After comparing the curves on a Peak DCA75—across the current test range—we can confirm that they are a close match to the MA856.
The default position of the internal treble trimpot is turned completely counter-clockwise, but as you turn it up, it will add high-end. The Internal Mids DIP switch will add low-mids to your signal by increasing the filter frequency of the first op-amp gain stage, while the Internal Gain DIP switch (the Turbo switch) will double the gain ratio of the second op-amp stage so that the diodes will clip more easily. The gain modes work just like they do on the Prince of Tone.
