I just ordered an Audix D2 and a Heil PR20.
They both start boosting at 1kHz and start rolling off at 5kHz.
Flat by 10kHz.
They also boost 150Hz 2 or 3dB.
I'm hoping these will capture the mids that I feel I've been missing.
This matches up well to the frequency response of my V30 speakers.
I only use standard tuning and Drop D from time to time.
I also use passive, vintage output humbuckers.
I can't wait to try them. I have a feeling that I'm on to something here.
