Happy Birthday Overdrive


In stock

SKU: 010 Categories: ,


The Happy Birthday Overdrive uses a Single Op-Amp for the distortion section and a JFet transistor for a makeup gain after a very unique tone section, which also affects the drive at the output. It’s a great light to medium overdrive with slightly fuzz like overtones.
