Unfortunately this fx pedal is discontinued as of now, so get your piece of history. Read why ...
The Ibanez NU Tube Screamer, the very first compact guitar effects pedals to incorporate a Nutube directly into its circuitry !
This pairing of Ibanez's Tube Screamer with KORG's Nutube technology, has produced an overdrive with exceptional dynamics, improved sensitivity and natural tube compression.
Nutube technology works like a 12AX7 tube, but is much smaller and more efficient. You will be amazed that this pedal reacts like an extra tube stage to your amplifier.
This thing will rocketeer your sound ! Any style !
The pedal works with 9v but has plenty of extra headroom with 18v !
