If you are willing to share any tricks or suggestions on how to keep the drums and piano out of the mic without blocking the view of it from the audience please share.
I tried all the tricks for double bass on stage for over the last 15 years...
There's always and always, too much drums leakage on the Double Bass microphones.
Tried all the different polar patterns, positions...
The only thing that works is throwing a Lavalier microphone inside the Double bass through the F-Hole, I've used an Omni Lavalier but also a Cardioid both work well, don't care too much about position, just throw it inside.
A good Lavalier like the DPA 4060 helps, of course it will sound better than a cheaper miniature microphone.
Adding to this I also stick an AKG C411 inside the double bass also, this is a contact condenser omni microphone but you stick it to wood like you would do on a Piezo pickup. Goes through the F-Hole also, and I stick it in the inside wood.
I use a mix between 3 recorded tracks the Lavalier, the C411 and the Pickup/DI.
The pickup/DI track might go in the mixing stage through the UAD "Woodworks" plugin which does wonders, it brings back some "Wood" sound to Piezo tracks. I might also use TC Electronics "Bodyrez" pedal. Both Woodworks and Bodyrez improve the sound captured from Piezo pickups
