has been extremely helpful in creating this plugin. [1] [2]
It's implemented with free tools such as DPF and Faust.

It is not considered complete, as some sections of Solina circuitry are
not part of the model, such as bass and formant sections.

(if someone contributes some electronic expertise to help on this part,
it's very appreciated)

means a faithful reproduction.

It's composed of 3 filters which are individually adjustable, and
switchable between 4 available modes.

Overdriving the input is originally able to saturate the filter.
For this reason, my version of digital filters include non-linear
saturation in the feedback.

The saturation is manipulated by gain sliders per-band, and by the
global pre-gain control.

This fuzz effect can process saturation over 4 distinct bands of signal.
The goal is to reduce the non-harmonic distortion amount, known as

This digital implementation is from the web-based project Pizzicato.js
[2], the plugin is a DPF conversion of this model, and it also provides
the oversampling feature.
