Lightning Boy Audio 23Fe+

Iron-Core Instrument Transformer

The 23Fe+ is a 1:1 ratio high-impedance audio transformer designed for use in unbalanced electric musical instrument signal paths (ie. guitar, bass, synth, etc.) in order to add some coloration and subtle compression. It offers a different tone from the 2020S and 2020 while offering more color. It is highly recommended to experiment with driving the 23Fe+ with a boost pedal to achieve more color and compression. You can also place it after digital effects to smooth out the sound with a bit of analog mojo.
