Versatile Gain Control
Experience seamless transitions between Clean Boost for transparent signal enhancement and Overdrive for rich, harmonic saturation, perfect for diverse playing styles and genres.
The API Select TranZformer LLX is a compact bass EQ and boost pedal designed for professional-grade tone shaping, integrating API’s iconic 3-band EQ circuit with a robust gain stage and transformer-coupled output. This unit delivers ±15dB of cut or boost across three bass-focused frequencies, offering precise control over low-end dynamics, midrange definition, and upper harmonic content.
Gain and EQ Capabilities
The LLX features a selectable gain stage that switches between Clean Boost and Overdrive, allowing players to choose between transparent signal amplification and harmonically rich saturation by driving the input OpAmp. The three-band EQ is tailored specifically for bass guitar, with each band offering a ±15dB range to adjust low, mid, and high-frequency content with precision. For the upper frequency band, the user can select between a peak or shelving EQ curve, providing additional versatility in tonal sculpting.
Connectivity and Power
Engineered to operate on standard 9V or 18V DC power supplies, the LLX adapts easily to existing pedalboard setups. The higher voltage option increases headroom, making it ideal for more dynamic or aggressive playing styles. A buffered bypass ensures signal integrity across long cable runs, while a -20dB output pad allows direct interfacing with line-level gear or studio equipment without signal overload.
Output Stage and Build Quality
The inclusion of a transformer-balanced output imparts the classic API warmth and depth, maintaining clarity and punch while enhancing harmonic complexity. Constructed with premium components and a durable chassis, the LLX maintains API’s high standards of reliability and sonic excellence in a stompbox format, making it a powerful addition to any professional bassist’s signal chain.
