Electro-Harmonix Bad Stone Phase Shifter Pedal - Classic Phaser Tone

In this review of the Electro-Harmonix Bad Stone Phase Shifter Pedal, the bottom line is straightforward: players seeking authentic 1970s phaser tones in a compact, pedalboard-friendly package will find the Bad Stone delivers. The reviewer highlights that the faithful recreation of the original circuit and six-stage phasing gives a rich, chorus-like sweep that responds well to guitar dynamics, while the Manual Shift mode and variable feedback add useful creative control.

Key Features

• Six stages of phasing: Delivers classic, lush phaser textures that range from subtle modulation to pronounced swoops, useful for both rhythm and lead parts.
• Variable feedback: Lets players dial in anything from subtle color to intense resonance, expanding the range of usable sounds from the same pedal.
• Manual Shift mode: Freezes the phase for static tonal shifts or ambient textures, offering an immediate creative effect without extra gear.
• Compact, rugged package: The die-cast enclosure saves pedalboard space while protecting the circuit for regular gigging and rehearsal use.
• True bypass switching: Preserves guitar signal integrity when the effect is off, keeping tone transparent for players concerned about coloration.
• 9V battery included: Lets you play right away without needing an external power supply, convenient for quick setup and testing.

Who It's For

The Bad Stone is ideal for electric guitarists and pedalboard builders who want a faithful vintage phaser sound in a smaller footprint, especially players chasing the classic 1970s palette. Its combination of six-stage phasing and variable feedback suits those who like to sculpt both subtle modulation and more pronounced phase resonance.

Players who need silent switching or ultra-low noise rigs should be aware that customer feedback noted the stomp switch can be loud and some users reported noise level as a consideration; if quiet switching is essential, a different unit or an external true bypass looper with a quieter switch may be preferable.

Pros & Cons

Pros

• Authentic vintage phaser character thanks to the original circuit design and six stages.
• Variable feedback and Manual Shift mode increase sonic flexibility and creative options.
• Compact, durable die-cast case conserves pedalboard space and stands up to regular use.
• True bypass ensures the dry signal remains intact when the effect is disengaged.

Cons

• The stomp on/off switch is reported by some customers to be loud, which can be distracting in quiet settings.
