Japanese heatwave.
Everyone's chased the perfect Tube Screamer. Wasabi hands you three of them: faithful TS808, TS9, and TS10 circuits on a single dial. Then it does what the originals never did: brings the lost low end roaring back and reshapes the clipping to taste. Three circuits, three bass voicings, three clipping modes add up to 27 distinct shades of overdrive, from a polite mid-forward push to a wide-open, asymmetric snarl.
It's the green box you already know, with the bite left up to you.

Evolution of the Tube Screamer.
The Tube Screamer family has earned its place as one of the most important overdrive circuits ever made. From the smooth, vocal midrange of the original TS808, to the brighter push of the TS9, to the cult-favorite TS10, each version has its own feel, response, and place in guitar history.
The TS808, introduced in 1979, is often considered the original Tube Screamer sound: smooth, compressed, mid-focused overdrive with a natural ability to tighten an amp and push leads forward. It became a favorite among blues and rock guitarists and helped define what an overdrive pedal could be.
The TS9 followed in the early 1980s with a very similar circuit, but a slightly brighter, more aggressive voice. It carried the Tube Screamer sound into a new era and became a pedalboard staple for players looking for more cut, bite, and presence.
The TS10 arrived in the mid-1980s as part of Ibanez’s Power Series. Long overlooked compared to the TS808 and TS9, it later developed a cult following for its slightly different response, focused midrange, and association with players like Stevie Ray Vaughan and John Mayer. Original made-in-Japan TS10s have become increasingly collectible, with prices often climbing into vintage-pedal territory.
Harby Wasabi brings all three classic Tube Screamers together, fully analog circuitry, in one pedal: TS808, TS9, and TS10. Each mode is carefully recreated with attention to the values, tolerances, and subtle component differences that give these circuits their individual personalities.
Built by our small team in the United States using high-quality components, Wasabi gives you the three most iconic Tube Screamer flavors in one compact, reliable, stage-ready pedal.
27 switch combinations
Circuit.
The TS808, TS9, and TS10 each defined a generation of overdrive. Wasabi puts all three circuits under one rotary switch, so you can pick your era at the turn of a knob.
Voicing.
Tube Screamers are famous for their mid hump, and for trimming your low end. Wasabi's voicing toggle lets you keep it Stock or restore the bass with Bass+ and Bass++, so your amp stays full at any gain setting.
Clipping.
The TS's symmetrical diode clipping is the heart of its smooth, compressed drive. Keep it Stock, switch to Asymmetric for a more open, harmonically rich breakup, or Lift the diodes entirely for a louder, amp-pushing boost.
Tube overdrive
Drive low ~2, Tone just past center toward +, Volume ~4. This is the lightest setting in these three examples: the pedal is barely breaking up, mimicking a tube amp pushed to the very edge of its clean headroom. You get a gentle, transparent grit that responds to your touch - dig in and it growls slightly, back off your picking or guitar volume and it cleans up. The slight bump toward + on the tone restores a bit of the top end that naturally rolls off at low gain, keeping it from sounding dull.
Mild rhythm overdrive
Drive at noon ~5, Tone flat at 0, Volume around 4. This is the balanced all-rounder. There's enough gain to give chords body, bite, and a little sustain, but not so much that strummed voicings turn to mush — individual notes within a chord stay defined. Keeping tone dead center leaves the EQ neutral and amp-like, so the pedal flatters whatever you've already dialed in rather than coloring it. It's the classic rhythm-crunch position.
Lead overdrive
Drive maxed ~10, Tone up ~+3, Volume at noon ~5. This is the singing-lead setting: full saturation for maximum sustain and a thick, compressed feel under your fingers. Backing the tone off toward the minus side tames the fizz and high-end harshness that come with high gain, fattening up single notes. The raised output level lets the pedal cut through a band mix and hit the amp's front end harder, which adds even more sustain and feel for solos.
