Sound Pure's Take

Condition: Used, Good

This analog pedal features controls for Tone, Gain, Level, and a toggle switch for Germanium or Silicon diode clipping options. It runs on standard 9V DC power and is perfect for adding responsive grit to any guitar setup. Compact, rugged, and handcrafted in the USA, it delivers classic drive tones with distinct vintage and modern versatility.

From Other (Miscellanous Used/Vintage/Consign)

The Speaker Cranker™ is a discrete, all-analog distortion enhancement device (i.e., not a booster), designed to give your signal some extra grit and a slight boost without drastically altering your tone. Think of it as sticking an extra preamp tube in your amplifier for more overdrive.

Single notes will blossom and bloom with rich harmonics and responsive, tube-like sag. Power chords will sound thicker and crunchier, a little more ragged around the edges. Complex chords will remain distinct and complex, as the Speaker Cranker is designed to preserve your tone’s integrity without muddying up the low-end, or “rounding out” the mids, or adding any top-end “shimmer,” or “sparkle,” or any of that other garbage. It’s your tone. Cranked. Ya got that?

Repeat after me: “The Speaker Cranker is an overdrive, not a boost.”

Switching

This device is true bypass and uses electronic relay-based switching. Audio will not pass without power.

Power

This device can be powered by a 9v battery or a standard 9-volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES!
