Quick Specs
- True bypass
- Variable rate control allows slow and smooth to rapid edge frequency sweeps
- Color switch adds Q and thins the moving comb filters - Tough and compact die-cast chassis - 9-volt battery included

The Small Stone was first manufactured back in the early 70s making
it one of the first compact phase shifters on the market. To this day,
the Small Stone is still the pedal to use when musicians want a fat,
warm analog phase shifter.


Connect your instrument to the INPUT jack. Connect your amplifier to the
AMP jack. Please note that whenever a plug is inserted into the INPUT
jack, the Nano Stone is ON and it is draining current from the battery.

The STATUS LED will light up when the Nano Stone is in effect mode.
When in True Bypass mode, the LED will be off. Use the FOOTSWITCH to
toggle between effect and True Bypass mode.

The RATE control adjusts the speed of the phasing sweep, turn RATE clockwise for a faster sweep.

The COLOR Switch changes the sound of the phase shift between a full
and robust phase shift in the DOWN position to a more pronounced
instance phase shift in the UP position. When in the UP position, notice
how the Nano Stone carves into the frequency spectrum hollowing out the
sound. Fundamentals and harmonics glide in and out for an extremely
pronounced shifting effect. Return the COLOR switch to the down position
and notice the fullness.


Power from the internal 9-volt battery is activated by plugging into the
INPUT jack. The input cable should be removed when the unit is not in
use to avoid running down the battery. If a battery eliminator is used,
the Nano Stone will be powered up as long as a wall-wart is plugged into
the wall.

The barrel connector on the front of the Nano Stone is for a 9-volt
battery eliminator capable of delivering 100 mA of current. The inner
ring of the 9-volt battery eliminator must be negative, the outer ring
positive. The units battery may be left in or taken out when the
eliminator is in use.

To change the 9-volt battery, you must remove the 4 screws on the
bottom of the Nano Stone. Once the screws are removed, you can take off
the bottom plate and change the battery. Please do not touch the circuit
board while the bottom plate is off or you risk damaging a component.

The input impedance presented at the Input Jack is 100 k-ohms. The output impedance at the Output Jack is 15 k-ohms.
