Another knob-noob question here. I just posted this in the TH500 mega-thread, but I'll try here as well since this page is getting more attention than I give it credit for. Good links will suffice for answers too...
1. What is the mid-frquency at noon? Aggy lists the knob's range as "Mid Frequency: 180Hz 1 kHz" but not its positions across the spectrum.
2. Coming from an Ampeg world, I always seemed to favor position "3" a la Ampeg's signature 5-position sweepable mids. Which knob position get's be closest to that stock "3," which I believe is 800htz? This will just be a starting point to further refine my tone.
Thanks again!
Semi-parametric EQ usually increase evenly by octaves (i.e., doubling the center frequency at equal intervals on the knob). My ear suggests the Aguilar circuit follows this general rule.
Therefore, 360hz should be at roughly 11 o'clock, and 720 at roughly 3 o'clock, with the maximum 1K at the full 5 o'clock setting. Given what sounds like a pretty wide Q (full octave) to my ear, setting an exact center point is not really that important, so my estimates should be 'close enough'.
So, 800 hz should be close to 4 o'clock or so on the freq knob.
