Description

Erica Synths BBD Delay/Flanger is one of the few bucket brigade delay chip based DIY modules. The module has been designed to provide variety of effects from flanger to delays with adjustable flavours and plenty of modulation possibilities. There is a built in LFO with selectable shape as well as a dedicated LFO output. The BBD also features CV over delay time with on-board attenuator, selectable feedback overdrive and feedback Send-Return connectors, so you can apply external effects on feedback signal. Maximums feedback settings put the module in self oscillation, so it can be used as an experimental sound source as well.
