The Warm Audio WA-TS Tube Squealer is an all-analog overdrive pedal that meticulously recreates the most iconic green drive circuit in guitar history. Delivering the signature smooth saturation and legendary mid-frequency push, this pedal is built around the authentic JRC4558D operational amplifier and premium through-hole components. Functioning seamlessly as a standalone blues drive or as an essential front-end boost for pushing high-gain tube amplifiers, the WA-TS acts as a cornerstone for any professional pedalboard or studio tracking rig.
The Iconic Mid-Hump and JRC4558D Chip
Cutting through a dense live mix or a heavy tracking session without raising the overall volume is a persistent challenge for guitarists. The WA-TS Tube Squealer addresses frequency masking directly by introducing a heavily optimized midrange bump. Driven by the authentic JRC4558D op-amp, the circuit provides asymmetrical clipping that mirrors the natural compression of driven preamp tubes. This specific EQ profile ensures that lead lines and complex chords sit perfectly in their own sonic pocket, standing out clearly between the bass guitar and cymbals without requiring aggressive post-EQ.
Tightening High-Gain Amplifiers
Tracking modern metal or heavy rock rhythm parts with extreme amp distortion frequently results in a muddy, uncontrolled low-end response. The WA-TS serves as an indispensable pre-gain tightening tool. By rolling the Drive knob completely back and maximizing the Level control, the pedal naturally shaves off muddy sub-frequencies while hitting the amplifier's input stage with a massive signal boost. An added TS9/TS808 toggle switch allows engineers to seamlessly transition between a slightly brighter, more aggressive attack and the warmer, rounded character of the earliest vintage iterations.
