The Little Sister boutique mid-frequency Boost to Push the Amp by Berserker Electronics

The Berserker Electronics Little Sister is a boutique mid-frequency boost pedal designed to help a guitar sit more clearly and prominently in a mix without drastically altering its core tone. Instead of simply increasing volume, it focuses on sculpting the midrange to add presence, punch, and definition, making it especially effective for cutting through dense band arrangements. A three-position frequency selector allows you to choose between 500Hz, 800Hz, and 1kHz, letting you tailor the emphasis from warm and thick to sharp and aggressive. With high headroom and a simple, intuitive layout, it can be used as an always-on tone shaper, an amp pusher, or a focused boost for solos and lead parts. The pedal is known for its ability to enhance clarity and “forwardness” without sounding harsh or overly processed.

Specs:

• Boutique mid-frequency boost / tone sculpting pedal
• Selectable frequency bands: 500Hz / 800Hz / 1kHz
• Designed to enhance presence, clarity, and mix cut
• High-headroom boost circuit for clean signal integrity
• Can push amps into natural breakup or tighten fuzz/overdrive
• Simple control layout (level/output + frequency selector)
• Transparent boost with targeted midrange emphasis
• Works well as an always-on tone enhancer or solo boost
• Compact handmade enclosure
• True bypass switching
• Mono operation
• 9V DC center-negative power supply
• Handmade by Berserker Electronics in the USA
