Youll find it hard to find an alternative to this must have distortion pedal! “The Tonebone Plexitube is the most versatile distortion pedal I own. Its also the quietest Ive ever used. I find all Radial products to be designed with sound quality easy operation and durability in mind.” – Daryl Stuermer (Genesis Phil Collins) Designed for Ultimate On-Stage Functionallity The Tonebone Plexitubes two distortion channels mean switching between rhythm and lead settings whilst performing couldnt be easier. Channel-1s scooped out mids provide the perfect thick tone for your chunky gut-shaking rhythm riffs and Channel-2 is optimised to offer all the face-melting sustained mids you need to cut through with razor sharp-solos. These are both augmented with individual contour controls and voicing allowing you the customisation to dial each tone to your preference. Also ultra-bright LEDs mean youll never be in the dark about your distortion even on the darkest of stages! True-Bypass Connectivity When the Plexitube 12AX7 isnt in use its true-bypass connections ensure your guitars original sound reaches the amp suffering no tone sucking on the way through. Photocell switching means activating the pedal is always smooth clean and pop-free even with high gain amps. The Plexitube even features an integrated effects loop on the lead channel which can automatically switch other pedals such as delay on and off for you when swapping channels saving you the frantic foot stomping!
