Hi,
everything sounds splendid, thanks for your work!
Albeit, I am sorry to report loud random pops with Herbie ch3. Normally I have a low cut in the input eq at about 120hz and cathode follower compression at about 66%, but I didn't change anything after loading this firmware. Random loud pops appear while playing, I perceive more popps while palm muting, but also after letting a chord ring. The popps sound very "digital", for lack of a better word and detached from the actual guitar sound, like a layer of it's own.
Preset attached, custom IRs though. Please let me know if you need more information if it turns out to be a bug and no user error (all other amps sound glorious so far).
Chris
