Friedman IR-X Dual Tube Preamp
Friedman · pedal
The Friedman IR-X is a dual-channel tube preamp pedal from Friedman Amplification featuring two 12AX7 vacuum tubes and built-in impulse response cabinet loading, allowing players to connect directly to a mixing desk, audio interface, or powered monitor without a traditional guitar speaker cabinet. The IR-X delivers genuine tube preamp saturation and power amplifier stage simulation with cabinet IR convolution, making it a complete amp-replacement solution for players who need Friedman quality tube tone for direct recording or in-ear monitor stage use. Guitar World reviewed it as a serious, premium solution for amp-free recording and performance.
