Ibanez has a long history of producing great distortion pedals with the Tube Screamer series.
But the TS range were solid-state pedals designed to get the most out of valve amplifiers – the new Tube King is a very different beast.
We're always a bit sceptical of pedals with built-in valves. We're not engineers so we don't know just how much the valve contributes to the sound.
That being said, the Tube King made our solid-state amp sound like a valve amp and that alone must justify the humble outlay.
