Compressor Guitar Pedal Source Comp by QSS27

Description

Product Overview

The Source Comp is a compact, analog compression pedal designed for electric guitarists who demand studio‑level dynamic control on stage and in the studio. Housed in a rugged metal enclosure measuring 3.94 x 2.36 x 2.36 inches and weighing just 8.8 ounces, the unit fits comfortably on any pedalboard. It features a 3.5mm audio jack for seamless integration with standard guitar rigs and operates on a 9‑18V center‑negative DC power supply (power supply not included). The pedal’s front panel includes three richly textured knobs—Threshold, Ratio, and Attack/Release—that allow fine‑tuned adjustment of compression depth, response speed, and overall feel. A multicolor LED ring provides real‑time visual feedback, changing hue as the compression engages, which helps players monitor effect intensity at a glance. The model number QSS‑27 and the distinctive “Compressor” color scheme make it easy to identify among other accessories.

Usage

Whether you are recording in a professional studio, performing live in a small club, or rehearsing at home, the Source Comp adapts to a wide range of musical contexts. Its transparent analog compression preserves the natural character of your guitar tone while smoothing peaks, making it perfect for clean arpeggios, nuanced fingerstyle passages, and high‑gain solos alike. The pedal shines in genres that rely on dynamic expression, such as blues, jazz, progressive rock, and ambient soundscapes. Because it runs on a standard 9‑18V DC supply, it can be powered from a dedicated pedal power unit or a battery pack for mobile setups. The LED feedback is especially useful on dimly lit stages, allowing you to see at a glance whether the compressor is active and how much gain reduction is occurring.

Why Choose Us

Our commitment to quality begins with the selection of premium components. The compression circuit is built around low‑noise op‑amps and precision resistors, ensuring minimal hiss and consistent performance across temperature variations. The metal chassis provides durability against the rigors of touring, while the compact footprint saves valuable pedalboard real estate. Each unit undergoes rigorous testing for signal integrity, power stability, and LED accuracy before leaving the factory. Additionally, the Source Comp is backed by a one‑year limited warranty and responsive customer support, giving you peace of mind that your investment is protected.

FAQ

Can I use the Source Comp with a battery?

Yes, the pedal accepts a 9‑18V center‑negative DC source, so a 9V battery or a portable power pack can be used, though a dedicated power supply provides more stable voltage for extended use.

Is the LED feedback adjustable?

The LED ring automatically reflects the amount of gain reduction; its color transition cannot be manually set, but the intensity changes proportionally with the compression amount you dial in.

Will this pedal affect my guitar’s tone when the compression is set to zero?

When the Threshold is set to its maximum (no compression) the pedal operates as a true bypass, preserving the original signal without coloration.

What is the recommended power supply?

We recommend a regulated 9‑12V DC center‑negative power supply with at least 500mA current capacity to ensure clean operation and avoid noise.

Is the pedal compatible with other effects loops?

Yes, the 3.5mm input and output can be placed anywhere in your signal chain, including before or after other time‑based or modulation effects, allowing flexible routing.
