Inside the VFZ

This pedal is an evolution of the standard vintage fuzzface circuit.

Every VFZ contains two vintage Germanium transistors that have been painstakingly hand-

selected and auditioned to give pure vintage tone. The transistors used in the VFZ are at least

20 years old, with some made as far back as the 1960's. We spend a lot of time, effort and

money to procure and select vintage transistors for the VFZ, sometimes sorting through and

discarding hundreds of vintage devices to find the very few that sound "right".

We have also sourced vintage "greencap" output capacitors for the VFZ. The output capacitor

is critical to the sound, and these capacitors are very sweet. Vintage specification resistors

(the old "carbon composition" type) are also used.

The specific transistors used in each VFZ give each pedal a unique personality with superb

tone and great dynamics.

The pedal has a set-point/bias control inside mounted on the circuit board. This control has

been set in the factory and we do not recommend adjusting it. Hard-copy instructions for

setting this control are provided with the pedal when purchased. Adjustments are, however,

made at your own risk and will void the warranty.

IMPORTANT NOTE ABOUT TEMPERATURE

Germanium transistors have always been sensitive to changes in temperature - it is one of

the reasons why the electronics industry moved from Germanium to Silicon.

What can you expect?

If the pedal is hot (e.g. left in direct sunlight or under stage lights for an extended period)

the tone will change, in extreme cases degenerating into a "broken transistor radio" sound.

This is completely normal for Germanium devices and, as long as the pedal has not been

damaged by excessive heat, it will return to normal once it has cooled down.

Trivia fact: in the 1960's and 1970's some studios would keep fuzz pedals in the

refrigerator until needed...

About your pedal

• The VFZ pedal is proper (3PDT) True Bypass. All True Bypass pedals may make a small

noise when switched – this is normal and does not indicate a fault in the pedal. Your

DingoTone pedal has been carefully designed to minimize this.

• Assuming the power switch is "on" (flicked up), inserting a lead into the INPUT jack turns

power on. Turn off the power switch or remove the input lead when not in use (be sure to

turn the amplifier off first!)

• Assuming the pedal is correctly powered and a lead is plugged into the input, the pedal is

in true-bypass when the LED is off. True-bypass will work even if power is lost (the LED

doesn't work if power is lost).

• The pedal will operate from an internal 9V battery only (please see warning below). For

best results, the battery should be a cheap carbon type. We have found "dollar store"

batteries to be the best.

• The battery can be accessed by removing the base-plate screws. If the pedal is not used

for an extended period, please remove the battery.
