Here is a demo of the incredible Schu-Tone Whirlpool Reverb that uses a real mini spring reverb tank to do its reverbing.
In this demo I am using a Eliasson Guitars Goldie into a Metro Amps JTM45 kit that I built and have the reverb running through the effects loop.
All of this gets mic'd up using the Royer 121 and SM 57 into Seventh Circle Audio Preamps into a Focusrite 18i20 interface.
