Going by the Pedalpcb Mammal Build Docs,
For Blue Note:
1. Change gain pot to 50kA
2. Change R6 (470R) to 1.2k
3. Change R101 & R102 (47k) to 470k
For #1, you could use any size between 50 and 500 to set the desired max gain. Technically the animal can get the low gain sounds if the Blue Note, it’s just harder to dial in that range. For #2, this only effects the voicing in the hot mode. #3 will have very little effect on the sound, as it’s just a voltage divider to set the Vref
