We’ve been lucky enough to find an original unit from the 60’s in great shape so we used it as a reference to make the most accurate replica of its preamp yet. We traced the original circuit and made our own schematic to stay true to the original.
As part of the circuit’s adaptation to a pedal unit we have put an extra effort to make The Windmiller Preamp as quiet as possible, so you barely notice its inherent hiss when it’s on. In addition, we have made the circuit a bit brighter, so you have a greater frequency spectrum on higher frequencies.
To make The Windmiller Preamp more versatile we have included tone cut controls for high and low frequencies. They are extremely useful for use on different amps and any kind of guitar. It’s going to be so easy to match it with different kinds of pickups for live use!
Due to its low input impedance The Windmiller Preamp will react in different ways depending on the signal source you connect to it. Plug it straight to your guitar before any other device and you’ll be delighted by its unique coloring. Put it after a buffer and you’ll get a super clean and linear booster with the addition of the Lo Cut and Hi Cut controls!
We couldn’t resist this cool feature of the original Grampian 636 thus it will be very useful as a signal monitor!"
We have a fully equipped workshop with certified luthiers and electronic engineers, equipped to do any work you need carried out.
For ten years we've been repairing, modifying and maintaining guitars, basses and more - for everyone from hobbyists to major touring artists.
