* Use a different autowah filter rangeChris Robinson2013-12-201-1/+1
| | | | Still just guesses, but this seems to avoid math problems with low peak gains.
* Redo the autowah effectChris Robinson2013-11-071-71/+71
| | | | | | | | It's now a low-pass filter with a cutoff that varies according to the input signal amplitude. There remains issues with apparent feedback in the resonant frequency with high resonance values. The actual cutoff range for the filter is also a guess.
