...tis a mystery... same drummer but only keys plus vocals this week (so not guitar) which certainly gave me more space in the mix. I have a Genzler Magellan preamp pedal that I bought specifically as it has two curve (EQ) presets that you can toggle between, meaning I can sweep them relatively quickly to find what works (perfect for the zero set up time at church). Three weeks ago "Curve A" at 3/4 sounded great, this morning "Curve B" at 3/4 which is a whole different profile seemed to work, along with cutting around 250Hz on my graphic EQ. But no rhyme or reason!
CURVE A (Blue): Provides a variable pre-shaped curve that boosts lows and highs while simultaneously cutting mids. The slopes are fairly gentle which keep the tone shaping very musical. This curve covers a wide range of sounds from flat to classic to modern depending on the position of the independent CURVE A control.
CURVE B (Amber): Provides a variable pre-shaped curve with attenuated high-mids and highs, a low-mid bump, and a slight roll-off of the lowest bass frequencies. Again, the slopes are fairly gentle which keep the tone shaping very musical. This curve is intended to provide sounds in the range of vintage amps and vintage cabinets that do not have tweeters. An independent CURVE B control is provided for this filter.
