Step Sister Frequency Boost (SOLD OUT)

Custom Little Sister Frequency Boost - Limited to 3 units

Step Sister takes the Little Sister concept and nudges the mids into a sweeter, more mix-friendly zone. Where Little Sister offers 500 / 800 / 1k Hz, Step Sister shifts the options to 600 / 700 / 800 Hz, trading sub-low thump for tighter punch (600 Hz), focused growl (700 Hz), and the familiar cut (800 Hz). Same transparent, low-noise boost engine with new center frequencies that sit beautifully with single-coils and humbuckers, especially into edge-of-breakup amps.

Highlights

• 3-way frequency switch: 600 / 700 / 800 Hz for quick, musical mid focus
• Controls: Boost (gain) and Volume (level)
• Circuit: True-bypass, 9VDC center-negative, low current draw
• Build: Hand-assembled with premium components, sparkle blue metallic finish
• Ultra-limited: Only 3 units, individually numbered

What it does: Tightens the low end, adds presence without icepick, and pops solos forward in a dense mix—without coloring the entire spectrum.

Perfect pairings: Strat or P-90 into a Princeton/AC-style clean, or humbuckers into a crunching solid-state/EL34 rig that needs articulate mids.
