Due to its low input impedance, the location of this versatile preamp on the effects chain is crucial to get the desired functionality. Here are some practical examples that will help you find the best setup for your Windmiller Preamp.
Townshend Setup
The Windmiller Preamp receives the signal directly from the guitar output jack.
The result is the same as Townshend’s rig: tone colouring; the gain knob turns up the amp’s preamp to increase saturation.
Preamp with Tone Colouring
You get the 636 tone colouring, but the signal boost can overload the pedals that follow before the amp.
This can be interesting for getting new textures from overdrive pedals.
Preamp with No Colouring
The Windmiller Preamp pedal gets the signal from a buffered pedal to create a transparent preamp. Use it to add gain to the overdrive pedals that follow but without the "colouring" to the tone.
It will be a louder version of the bypassed signal. Use the EQ controls to shape and fine-tune your tone.
Transparent and Linear Boost
The Windmiller at the end of the effects chain will act as a regular booster: louder signal with the least tone colouration possible.
If a buffer or effect circuit is placed before the Windmiller Preamp, isolating the pickups and, at the end, converting the signal to low impedance, then the Windmiller Preamp will react as a transparent booster without adding colour.
This set up is ideal for solo parts or to recover some signal lost in a long signal chain.
