Warm Audio - WA-TS Overdrive - Guitar Effect - 1 Piece

The WA-TS (Tube Squealer) is a solid-state overdrive pedal that combines three legendary "screamer" effects into one device. It offers an accurate reproduction of the original Japanese circuits from the late 70s to 80s – 808, TS9, and TS10 – along with modern features for versatile use on stage and in the studio.

Three independent modes provide authentic characteristics of the original circuits, complemented by features such as a mix knob for adjusting the balance between clean and distorted signals, a pickup voicing switch for optimal response with single-coil or humbucker guitars, a selectable voltage boost for greater dynamic range, and a switchable true/buffered bypass. The fully analogue circuit, featuring JRC4558 op-amps, discrete transistors, and JFETs, delivers natural dynamics, low noise, and faithful response.

Three legendary circuits in one pedal

The WA-TS faithfully reproduces three original Japanese overdrive circuits – 808, TS9, and TS10 – which have made their mark on the history of electric guitar. Each mode utilises specific circuitry, altering dynamics, frequency characteristics, and response to playing style.

Flexibility for any setup

The Mix control allows the blending of clean and distorted signals for precise tone shaping. The Pickup Voicing switch optimises frequency response for different pickup types.

Increased power and headroom

The built-in voltage doubler enables switching between 9 V and 18 V, increasing headroom and tone clarity at higher output levels – ideal for enhanced dynamics and responsiveness to player articulation.

Premium components and construction

The pedal uses JRC4558 op-amps, discrete transistors, JFETs, and diodes to ensure stable and authentic sound with minimal noise. Its durable metal chassis guarantees longevity in demanding environments.
