Effectrode Tube-Vibe Chorus/Vive All Tube: Circuitry for the ultimate in audiophile performance  low backgound noise and stacks of headroom for a rich and musical Vibe tone. The fundamental tone and drive of the Tube-Vibe can be further tweaked by swapping the 12AU7 tube with other 9-pin varieties, such as 12AY7, 12AX7, etc to boost and push your favourite vintage/boutique tube amp into overdrive for some seriously thick/sustaining tones. Dual LFOs: In Classic mode the Tube-Vibe authentically sculpts the deep, swampy Uni-Vibe throb and in Smooth mode it reproduces dreamy, ethereal chorus voicings. Additionally, the LFO can be halted (frozen) so it can work as a sweepable notch filter to create hollow sounding scooped textures. Chorus/Vibrato Switch: Selects between the classic Hendrix/Trower Uni-Vibe chorus and de-tuning pitch-bend vibrato. Additionally, the internal Blend trimmer allows further fine-tuning of the vibe throb. True Bypass Switching: With Effectrodes unique anti-pop or thump footswitching circuitry utilising sealed, gold-contact relay to eliminate the possibility of dirty contacts degrading the sound and minimial internal audio path.
