How to build an effects pedal for overdrive.
The Thunderdrive Deluxe LTD is an overdrive pedal kit that will provide a strong clean signal boost in the
early gain settings and smooth distortion at maximum gain settings. Adjusting output and distortion controls
provides a wide variety of tones in spite of its simple construction. It is capable of overdriving the preamp
section of your guitar amp or adding its own layer of distortion at lower volume. This version is equipped
with a three position diode selector switch.
The switch offers three different settings and tones. The top position is the classic silicon clipping diodes
used in the original Thunderdrive. The middle position gives you the lifted diode “turbo” sound from the
Deluxe model. The bottom position is a new setting limited to this version using germanium diodes for a
warm vintage distortion.
