A few months ago, I’ve posted a note on an overdrive. The main issue of this kind of non-linear filter is aliasing, a process that adds digital acoustic content. The best way to solve the issue is to oversample the input before processing the signal.
There are some effects that are simpler than other. Digital ones are generally easier than analog ones, and purely digital filter are also easier than digitally-transformed analog ones. Linear filters such as passband, cutband, … are easy to digitally design, chorus can be achieved through some spectral computations, delay and reverbation are computationnally expensive but easy to code.
It said that analog devices have a unique sound that digital devices cannot achieve. In fact, much is due to the simplications that occur when digitizing an analog device. One of the most blatant examples is the overdrive, which I took from Simulanalog.

After last week review, I’ve decided to try another book from a much higher standard publisher, Springer. The price is also far higher, but it covers what I think are the current best supports for building automation.

I’ve recently burnt the tone circuit of my Cort GB-74, so I’ve changed it for a Seymour Duncan STC-2A. The basic wiring diagram does not include all the options I had on the original diagram, here are the (small, really small) modifications and some impressions on the STC.
