I'm starting to plan-out an Ovation Breadwinner “Tribute” build. I’m not going to replicate the on-board electronics, but build a modernized version using contemporary components. Overall, it’s pretty straight-forward, but I’m not sure what the parameters on the mid-scoop/notch filter should be: center frequency, bandwidth & Q-factor. I’ve dug through all the Breadwinner fan pages I can find, but haven’t been able to find the specs. Also, since this is a “tribute” and not a reproduction, I’d like to pick parameters that are “contemporarily useful” vs just duplicating what was done. I remember some folks thinking the notch was too deep. That said, even if I get exact specs, I’ll still likely build the notch filter with trim pots so I can fine adjust the response.
