Timber is a very flexible wave shaping module that can produce rich timbres by adding harmonics to simple waveforms (triangles and sinewaves) or any other signal. It has 2 different unique wave shaping circuits, the WAVE DRIVER (I) and the WAVE FOLDER (II), and a voltage-controlled crossfader to fade between the specific circuits or between one of them and the clean input signal.
Novel take on the Serge style wave folding circuit & more...
Both circuits share the same control voltages: the SHAPE, which sets the input amplification before the wave shaping circuit, and the SYMMETRY control, which adds voltage offset to the input signal to provide various asymmetric overdrives or wave folding sounds. There is also voltage FBK CV jack, which, when provided with positive voltages, feeds a respective portion of the output signal back to the input, which results in chaotic and aggressive behaviors. It is calibrated to work well with 5V gate voltages.
The WAVE DRIVER (I) is an overdrive circuit with one folding stage, and it has 2 configuration 3-way switches (9 different configurations). The drive switch can set the overdrive character to SOFT or HARD or something in between. The FOLD switch can set the folding threshold to HI or LO, or it can turn the folding stage off in the NO position.
The WAVE FOLDER (II) is a novel take on the serge style wave folding circuit, which has specific behavior to abuse the high gain of the input amplification stage to provide rich high-frequency timbres with higher settings of the SHAPE parameter. It has a configuration switch that can either activate a clean 4 stage wave folding in the OK position or a highly asymmetric folding stage in the KO position that provides a strange metallic character. The NO position provides only the very last overdrive-folding stage.

You can build your own THT version of Timber with our TIMBER PCB. You will need, however, to source the components. Go through the complete assembly guide below and make sure that you understand all the steps. The assembly guide includes a BOM.
Please be aware that the THT DIY version of Timber has a slightly different sound color than the assembled version. It is caused by the nature of THT parts. The function remains identical.
