Got EQ? Analog that is….

Quick google says these are the actual frequencies/Q factors of the Mesa graphic EQ:

80Hz -> R=470 / L=1H / C=3.3uF ---> Real F=87.61Hz / Q=1.171
240Hz -> R=470 / L=0.39H / C=0.47uF ---> Real F=371.7Hz / Q=1.938
750Hz -> R=470 / L=0.22H / C=0.22uF ---> Real F=723.4Hz / Q=2.128
2200Hz -> R=1K / L=0.068H / C=0.15uF ---> Real F=1576Hz / Q=0.6733
6600Hz -> R=1K / L=0.033H / C=0.033uF ---> Real F=4823Hz / Q=1.000

Without a frequency analyzer it might be hard to find the exact frequency and Q values, but the range is there for all but the "240 Hz" which is apparently actually 371 Hz and the Ibanez maxes out at 360 Hz.

But you can probably get away with just using that, or even just matching them to the labels on the front panel.

Range of the sliders might also be different. Finally the behavior of the sliders are likely to be different so you can't just copy Mesa EQ settings and call it a day. Apparently the Mesa graphic EQ is pretty terrible at this where the middle of the range barely does anything and then there's a lot of effect at the extremes.

@FractalAudio made a great post here.
Yeah I compared to Ibby to the Mesa 5 band pedal pic. The thought of trying to be exacting in the maths checks out in your response and as such, not an activity (or pedal replacement) I am going to seek out in my spare time :LOL:

Yeah but realistically, if you want a Mesa 5-band style EQ then the Ibanez would be a good option. Just wing the knobs to a ballpark and call it a day. Probably works well enough. If it doesn't...well, there's a lot of other frequencies to explore.

Yep. Or just use the FAS 5 band and use what I own. AKA where's the fun :grin
