Radial Engineering Plexitube
12ax7 equipped tube distortion
clean, rhythm and lead in one pedal
insert loop for effects on lead channel
true bypass

This is the plexitube. Radial's take on what a marshall plexi sounds like.
Features are quite good. Although the controls are shared making it more like 1 and a half channels as opposed to 2 completely separate channels.

Individual controls: Level, Voicing, Contour, midboost switch.

Shared controls: Drive (although drive 2 is adjustable on the side), Low, High, Top end.


Most of the controls are active, meaning they are sensitive, even with the slightest turn, can make a huge amount of tonal changes and all controls interact with each other of course.

The FX loop is a cool one, just like the trimode, allows you to hook up effects to the lead channel like a delay for your solos so when you kick that channel in the delay will come in at the same time and there's your lead tone!

The mid switches are specific frequencies which are listed in the manual, so you'd have to refer to it to get more detail on exactly what's happening with the midrange.

I don't know why Radial keeps advertising this pedals as 3 channels with a clean. It's a distortion pedal and the clean is the bypass, so it's not the pedal giving you the clean channel.


First of all, this does not sound like a plexi to me whatsoever. It sounds just like a good distortion pedal with a sort of vintage vibe to it. Although most of the tone to me is still a bit too bite and harsh, and sometimes shrill. The highs, even when tweaked are still shrill. There is this annoying piercing high end that I keep hearing even with the highs rolled down and the EQ tweaked properly I can't seem to get rid of it. I believe it's just part of the sound of the pedal.

It's a tight sounding pedal however, very clear and the distortion is very stiff, too stiff. That tube amp sag and saturation that I'm used to hearing is definitely not there. The plexitube is definitely designed to go with a tube amp to try to compensate for the shrill high end that it has. Pair this up with a solidstate amp and you're in trouble!

So I feel bad to say that I'm not happy with the sounds of this pedal! It's falsely advertised and sounds nothing like a plexi, and it's got this annoying fizzy high end I can't get rid of either. The vintage amp sag is not there either.


Overall I'm not impressed with this one. I'm not sure if I got a lemon? But I doubt it, most radial stuff has always been great build quality-wise. But I guess I'm just not into this pedal as I originally thought I would be. It's definitely got enough gain to do metal but it doesn't sound like a plexi and is not 3 channels either. It's 1 and a half channels of marshall-esque distortion. I'm glad I sold this and would look elsewhere for a plexi sound in a box, so far nothing sounds as close to a plexi than a carl martin plexitone to my ears.

Distortion lamp two channels. Many réglges wholesale equalizer galore in the form of knobs and switches + Gain setting common to both channels + two independent volumes.

I feel that the channel 2 (lead) is not identical to the first hand is over medium-high. Loop particular effect it is a female jack stereo in which a split stereo cable is plugged into two monos used to create the effects loop by putting pedals in between.

Built like a Tank


It 'n there's no need for manual but easily found online.
Must spend time knobs have very reactive / effective as the switches, they interact with each other and with the volume.

Not simple but very flexible, this box will fit all rig.


This is simply excellent. It is clearly in the british and british hotroded. It is in Marshall, one can clearly evoke the plexi. Is this the sound of a non plexi, but the grain is in fact closer.

The foot knobs but is responsive to the limit set is:
-If you set the gain between 12h and 15h by lowering the volume of the guitar you will not get that nice crunch that goes well
-Wise if you stay on the gain you mean between 9am and 11am to find some thing that crunch elegantly (coarse slightly compressed).

- With a slight boost before or TS can get side slash. this config is very very efficace.Là crunch begins to be very beautiful, the manipulation knob skyscraper works very well in this case.

I use it with a good LP and a small Ibanez 15w.Avec a TS and boost upstream.

it well there's two real channels configured in the passage lead you done very well out of the mix.

Very nice headroom with the various settings I think we can do anything except perhaps search of the American ultra distortion own type Mesa.Mais good there should not buy Mesatube the Plexitube ...

Beautiful vibrant, heat, rich in harmonics


I use it for 2 years. No major fault in my opinion. this is a very good product, very good priced new Cygnus.

to date this is the best distortion I had in hand, I would just try the Bogner Ecstasy RED to see if the grass is greener.

Blah blah site builder.
Otherwise, the pedal seems very robust and high quality components
Also gripe about two disto not completely independent.


So this is my first Tonebone and we do not rule 2min especially that there are 2 channels with the same criteria and it must take a little time to shop around.
The manual is in English, I did not read but pre registered setting helped me understand a little different settings.


The sound is very good, I do not know Plexitube so I can not tell if it's the same sound but this one suits me very well.
Still little regret at the 2 channels that do not allow me to have two different sounds, and after do with the effects loop on channel 2 ...


So yes it's very good stuff, yes the sound is very good but I put only a 7 for 2 channels not fully independent and for the price as this pedal is really not given by purchasing new

Radial Engineering Plexitube
Distortion pedals lamps 2 identical channels (two in one hotbritish PDAL, concrtement) with true bypass loop disables (royal to trigger a noise gate at the same time as the distortion)
Construction inspires confidence, chassis indestructible. Beware, as many pedals lamp, the power supply is Owner '(15v I think)
Rglages ultra-complete with switches for boost / cut of mdiums and treble, and switches to gain an edge, a drive and volume per channel and a common dual-band eq ... The lack of mids SETTING THE s'avre do not teachers at all.

In short, more difficult to complete pedals for ...


It will be forcment time that the pedals more like an RULES Tage pramp bte a distortion. But it is very easy to find a playable (even it sounds bad RULES, arf ...)

EDIT: Beware of the high output of the pedals, if you have additional downstream effects that makes them easily saturate. It is better to know ...


I took a slap ... I tried a flop distos pedals, lights or not (mxr, boss, maxon, Guyatone, etc ...) and for me the Tonebone (I also tried the tri-mode) are of the few not to blush before a real channel amp. It marshallesque desire, subtle or angry, friendly instrument ...
Addictive at all.

EDIT: be careful, because the transparency of its sound quality dpendra also the amp that is derrire. I tried to live with a PC to simulate the convolution HP on a fender combo on my dragon head on the clean channel, in the back of the loop ... the grain is radically DIFFERENT every time;)


From the moment I plugged the pedals, I jou one hour continuously c'tait so good and it's an aficionado of pramps rack and amp heads, so the any high voltage lamps, which speak so c'tait not win the base ...

Tri-Mode with the registry that covers most US grain, radial al released a pair of pedals that will delight the world ...
