The axe model defaults to 60, I'm not sure what specific vintage it's modeled after, and wanted to know what's the correct bright cap value for the JMI mid 60's TB.. Does anybody know?
One of the differences between older AC30's and the Korg RI is the bright cap (C8..) on the Brilliant channels vol pot. On the Korg the value is 120pF, in the original circuit the value was 100pF. The cap will increase brightness on lower vol settings, but as the vol is turned up the HF boost will gradually decrease and when reaching a certain level (50-60%, I think) the cap will have no effect.
