Can a CA3130 IC be swapped out with an OP275 ( plug and play, no modifications)?
The reason I ask is because the BJF Honeybee (and YellowShark) uses the CA3130 whereas the Mad Professor Sweet Honey Overdrive. Although to my ears the pedals do sound different, they are supposed the be the similar.
If not, are there other IC's I can experiment with on the Yellowshark layout?
Sorry, I don't know jack about that circuit, but those IC's cannot be swapped interchangeably. The OP275 is a dual op-amp, and the CA3130 is a single op-amp. Check the data sheets for the pin-out differences.
Thanks for your reply. I am a DIY hack. I am really bad about understanding datasheets.
