Guitar Player Editor's pick!

2-channel tube distortion pedal combines the natural warmth and harmonic generation of a 12AX7 tube with the control and saturation of Radial's unique multi-stage solid-state drive circuit. This combination provides incredible gain with tons of overtones and, when combined with their unique passive-interactive EQ, produces four generations of Marshall Plexi tones worthy of a Shakespearian Ode.

Designed to enhance onstage functionality, the Plexitube features two distinct distortion channels for on-the-fly transition between rhythm and lead settings. Channel-1 has been optimized for rhythm with chunk rhythm tones and scooped out mids for a thunderous wall-of-sound and complete world domination. Channel-2 is optimized to produce razor-sharp cut for solos and sustaining mids that are so smooth, they can make a grown man cry. This is augmented with an effects loop that can automatically turn your delay on for leads. No tap dancing!

When the Plexitube is off, true-bypass connectivity ensures the natural tone of your guitar goes directly to your amp without obstruction or a tone robbing load.

Plexitube Setup:
The Plexitube is your 'Plexi-in-a-box'! Just plug the Plexitube output into your amp to open up a world of tube driven British rock tones. The separate trim, drive, contour and EQ controls give you instant command of both rhythm and lead distortion settings as well as a true bypass mode that ensures that nothing gets in the way of your pure guitar-to-amp tone.

But that's just the beginning because you've also got a foot-switchable effects loop at your disposal that's there when you need it and out of your clean signal path when you don't.

You will be amazed at the breadth and scope of the sounds just waiting to be discovered in this truly versatile pedal!

12AX7 equipped tube distortion
Clean, rhythm and lead in one pedal
Insert loop on lead channel for effects
True bypass clean for natural tone
Huge chunky rhythm settings with scooped mids

The Radial Tonebone Plexitube takes metal guitar one step beyond anything you have experienced so far. God save the Queen!

Had it for two years

By Jesse J

Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

I tweaked it for hours through many of my guitars (Les Paul, Strats, Tele, SG) through a Fender Vibrolux and was always unsatisfied. This thing has a lot of gain, more than I needed. The chords tend to mush up with the gain and I could never EQ it like I wanted even though it offers a lot of knobs and switches. So much crunchy fizz to it. Not the kind of plexi tone I expected. I even rolled off the gain to try to clean it up, but then that just defeats the purpose of the pedal and would just weaken it's sound. I could get away with the tones if I played two strings at a time while power chording or rhythm, but a pedal this expensive... I expected much more. Channel two gets your guitar screaming for a great lead, but it is so noisy it's ridiculous! Who knows, maybe it'll work out for you, but it just wasn't my cup of tea.
It's got a lot of customizing options, and you get a variety of tones.
Is very durable and well built.

Finally, A Pedal That Does The Job

By rude335

from Undisclosed

Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

I play through a 65' Twin Reissue because cleans are very prominent in the style of music I play. Unfortunately, so is distortion. I couldn't get the cleans out of Marshalls, so I decided to use a pedal as a means of distortion. I went through EVERYTHING.All the pedals I tried either sounded extremely harsh or really thin.I was fed up with it but decided to take one more shot with the Plexitube. Let me tell you, totally worth it. This pedal is not only the most versatile and full I have ever used, it is also the quietest and does not effect your tone at all. Buy it. It won't disappoint.

Amazing Pedal

By CeryBertum

from NY

Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

I looked at about 10 different distortion pedals and I was disapointed. They all sounded digital and I have a very big problem with digital sounding pedals. I started looking at a the Tonebone plexitube Hot british distortion and I was amazing with the sound. This pedal is very optional. The Radial distortion can play anything from Stevie Ray to death Metal. I was Very impressed and I would recomand this pedal to anyone that loves realy tube tone.

The ONLY rock distortion!

By Michael N

from Shelbyville, TN

Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

I have searched for a versitile distortion that sounded full and clear to my ears for about two years now. Let me tell you, i search no more! I run this pedal from an ibanez EX (super distortion in the bridge position)to a peavey bandit combo amp. The amount of different sounds you can produce from the hot british distortion is absolutely unreal! It has two channels for lead and rythm, which is SO helpful. I gave a nine on value because it is very expensive, but it is worth every pennie! It has a hard metal casing, so it won't break on you. From that border-line blues crunch to high gain metal madness, the plexitube hot british distortion is the only rock distortion you will ever need.

Awesome Pedal

By VoodooChild-k7jdo

Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

You will not find a nicer distortion pedal with as little noise and this much body. It is very full, has plenty of variables for settings, and the 2nd channel is a giant plus. I did have to turn down the distortion for the second channel though, it was just too much. With the gain knob cranked it can become somewhat fuzzy, but any pedal is like that. This is very good for rock, and you can even pull a Tube-screamer sound for SRV too. I have owned and played quite a few pedals, and I am still impressed at the lack of hum and buzz. The sound is fabulous too, very full and real, not hollow and lifless like many others. I think the price was a little much, but other than that well worth it.

Master Of Plexitube!

By SnakeHead

from bakersfield, CA

Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

After playing guitar for 25 years and owning every distortion pedal on the planet, I can say that this pedal is the best I have ever owned. If you want gain, you have A LOT OF GAIN!. The same goes with treble, bass, mids, filters, ext. the flexibility is can go from an AC30 to Bogner Ubershall, and everything in-between. If you ever wanted a Bogner/Diesel/Soldano in a pedal, this is the ticket. The only other pedal in this class is the Hot British, but if you need two channels this is the way to go.


Best distortion Ive ever had

      Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

      I run all my pedals through a switcher into a clean amp. I have had lots of distortion pedals over the years trying to find something creamy like Eric Johnsons lead tone. Im not saying it sounds like EJ but its in the ballpark. Its sweet spot is more high gain than EJ but its my favorite pedal ever. It has a lil' something in the midrange that NO other pedals have that smooths the notes out. Ive had Boss stuff, Fulltone, MXR, Way Huge, and tried countless others in the stores. Anything that was close still does not compare side by side. Anybody who doesnt thing this pedal is 9 kinds of awesome is out of their mind.


      Marshall in a box!

      Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

      Pedal delivers Marshall goodness in spades. I have channel 1 set up for a classic rock Marshall crunch that responds to the volume knob just like the real thing. I tweaked the gain for channel 2 for a hard rock Marshall sound akin to what I can get from my JCM2000 TSL100. It just roars, and I love it.I take a point off on features for having the gain for channel 2 in a trim pot, even if it is externally accessible. The problem is, on a crowded pedalboard, you'll never be able to set it, so be sure you have it where you want it before you mount it on a board.The mid voicings are very useful for fine tuning it to your amp. The pedal can do anything from light, compressed, mid-heavy overdrive, to roaring, scooped (in a good way, not in the guitar-store-shred-kiddie way) full-blown distortion. More gain than you'll ever need. It is relatively noiseless, but at higher gain settings some can creep in, naturally, so be sure to have a gate or NR pedal somewhere.This pedal is on an analog board I built with a Full-Drive 2 MOSFET: the perfect compliment. I'm using it for praise & worship and classic/hard rock. Awesome pedal, awesome quality, awesome tone.


      Eh ... too much money I think

      Comments about Radial Engineering Tonebone Plexitube Distortion Pedal:

      Had it for a week or so now and I have to admit that, to me it's not worth the price. I'm struggling to get the plexi-ness out of her. Not sure why they called it plexi-tube, but I'm nowhere closer to that "plexi-tone".It's a versatile lil' pedal for the features it offers, the concept is great, however the effects loop strangled my sound/volume and I had to turn it up a little and it never really incorporated the effects into the sound? It was a good idea though. The effects loop is only available for Channel 2, not Channel 1 either.The knobs can be a little confusing at first, but upon reading their manual it'll give you a quick reference on how to operate her, etc. It even gives you a few ideas to start off with, which was cool. It helped, but never really satisfied me.Channel 1 is supposed to be a hot rodded Marshall type sound with minimal Gain invested in it. I could live with this channel if I had to.Channel 2 is supposed to be a lead channel but it was too rough and harsh, no tone and nothing pleasing about this one at all. I'm a metal head and this was the most disappointing channel of them both. It's supposed to be the higher gain channel.I'll try fiddling with the little drive pot in the casing and maybe switching out the tube in her ... but so far I'm very disappointed in it.I tried it in a tube amp and a solid state amp (both on the clean channels and straight into the return jack/power amp in). I turned the knobs for days, no luck.Maybe you'll have the luck. I'm not all that happy about shelling out this much money for what I got.
