Thomas Hafemann - Invidious

Thomas Hafemann

DIY pedals and amplifiers. Sound samples for small amplifier builds using subminiature tubes, miniature preamp tubes and old radio tubes.

Here you will find some miniature builds using SMPS (switched mode power supply).

The main goal is to find a good tone with low wattage for home practice.
