Silver Birch

Silver Birch

The Silver Birch is an overdrive with distortion-capabilities that rose from the moonlight, inspired by a number of Model-T clones. From tip to bristle, this dual channel overdrive uses CMOs Hex Inverters to achieve a tube-like sound. Warm and round. Boomy and haunting. Rich and cutting. The options are limitless.

  • Channel Order Switch

    In Parallel mode, both Channel I and Channel II contribute equally to the pre-equalizer tone. Boosting Channel I gives more lows, and Channel II gives more high-mids and highs.

    In Series mode, Channel I is used as a pre-amp for Channel II. This means the Channel II gain setting controls how big and loud the Series mode sounds. With Channel II gain turned down, tone focused into a tight, muted sound --- with Channel II gain turned up, the Silver Birch opens into a mean, huge howl of distortion.
