Warm Audio announced the Tube Squealer and Throne of Tone overdrive pedals on October 8, 2025, according to Gearnews¹. Guitar.com reported the two pedals as homages to "some of the most iconic overdrive circuits in guitar history"².

The Tube Squealer is Warm Audio's take on the Tube Screamer, with three selectable voicings: 808, TS9 and TS10². It adds a Mix knob to blend clean signal with the overdrive, a pickup-voicing selector for single-coil or humbucker guitars, and an external voltage booster for headroom². Inside are JRC4558 op-amps, discrete transistors, diodes and JFETs, with asymmetrical clipping². MusicRadar reported that all three modes use the JRC4558 op-amp for the tone stage, the TS9 drive stage uses a JRC4580, and the TS10 adds an extra resistor³. MusicRadar also reported a switch between true and buffered bypass³. The Tube Squealer is $149 and is sold exclusively at Guitar Center in the US and through authorized retailers worldwide².

The Throne of Tone is a dual-sided overdrive inspired by the Marshall Bluesbreaker and the boutique pedals that followed it². Each side has Volume, Gain, Tone and Presence controls, a King or Blues voicing switch, a Boost, Overdrive or Distortion mode switch, and a high or low gain switch⁴³. Each side's Presence control is adjustable from 500Hz to 2.3kHz². There is a channel order switch, a rear-panel send/return loop for placing pedals between the two sides, and a voltage doubler running internally at 9V or 18V²⁴. Warm Audio lists 24 diodes and JRC4580 and TL072 op-amps across two fully analog circuits². Guitar Pedal X gave dimensions of 127mm W x 171mm H x 67mm D⁴. The Throne of Tone is $229²⁴¹.

Warm Audio founder and president Bryce Young said of the Throne of Tone:

Guitar Pedal X described the Throne of Tone as leaning "a little more into the KOT versus the BluesBreaker" and called it "not necessarily the most pedalboard-friendly unit"⁴.
