Look up onEffectrode Tube Drive From Effectrode:The Tube Drive contains three dual triode tubes biased to produce extremely symmetrical signal clipping across 6 cascaded gain stages0In practice this means the pedal responds empathically to pick attack with a smooth and graceful breakup characteristic on low drive settings, producing an expressive warm blues tone.Increasing the drive introduces rich and musical harmonic overtones that pack serious punch for a larger-than-life, hot-rodded amp tone.The Tube Drive won't mask the natural sound of your guitar and amplifier and sounds distinctly different to pushing an amp with a solid-state diode clipping (or even hybrid opamp/tube) overdrive pedal.
