I am in the process of building a Hotcake and I found with the LM741 that I am getting a lot of fizzy sounds at low gain. I was reading over at Madbean Forums that the Bluesberry mod was supposed to help this by smoothing out the decay notes. A member over at Madbean Forums (Timbo) gave some instructions on implementing this mod.

The “Bluesberry” mod, which puts a 1N914 from pin 2 (cathode) to pin 3 of the IC, and from pin 2(cathode) to ground (pin 4).

I am using a layout by BeeJive and will free float these diodes to test with and see if it solves my issues. If not, I will start to look at other ICs or other component values.

Edit: Still have the issues. Need to look more into it.
