denied's review"Top notch OD"

Diamond Pedals J-drive MK3
- Two independent sections, OD and boost

- True bypass

- JFET input

- High quality components, impeccable build quality

- 9v battery or standard boss style adapter operated

- Controls for drive, warmth, volume, and gain

- Bright switch


Its a little more than your standard simple OD pedal, but is actually pretty straightforward to use.

I am particularly happy with the fact that the boost and OD can be engaged independently. Most dual OD/boost pedals must be on for the boost to work. With the J-Drive, the boost can be engaged at any time.

I also like the fact that the boost runs in front of the OD, so acts as another pedal running a hotter signal into the OD circuit.

Standard 9v (-) input is convenient as well.

And of course, Diamond definitely build their pedals to withstand the test of time and beatings of the road. This one isn't going to fall apart in a hurry.


One of the best sounding OD pedals you will come across. Think smooth. It can get a little gritty when dialed in right. But for the most part it is smooth and creamy sounding, absolutely perfect for mellow type leads. very rich in harmonics. Not the most responsive pedal I've ever used, but that's not really what it was designed to do.

Fairly transparent, doesn't have quite the mid hump of a tube screamer. I am a big fan of the warmth know in lieu of standard tone controls. It acts a little like the opposite of a glass knob. The bright switch is similarly powerful. Warmth knob up, and the bright switch off sounds absolutely fantastic.

The boost has quite a bit of gain on tape. Works really well as either an extra gain stage in front of your preamp or to add drive to the OD.

True bypass switching, so your bypass tone is preserved.


Another incredible pedal from diamond. Super solid construction, and fantastic smooth sound. With the absurdly low price these go for used, it is really difficult to beat. I find myself recommending it very often. Actually a lot more compact than I was expecting, fit on the board nicely, and I appreciate the position of the jacks.

Highly recommended.

Diamond Pedals J-drive MK3
- What are the effects or types of effects available?

While the menu: Disto and / or Clean Boost

- What technology is used? (Analog, numrique, lamp ...)

All analog, the sound of the guitar is more than respctc'est velvet.
The quality of the product immediately jumps to the eyes.



Some knobs, one button "BRT" (read his british) available only on the model
mk3 seems to me there.
Everything is very good manufacturing and use is simple.


- Effects are they effective, suitable and adequate ralistes?

We are in the high end, the cream of the cream, the top of the pav.

Which instruments do you use?

For my part of a 1977 Telecaster and a Vox AC30.

The pedals fully respects the sound of the guitar, the knobs have a vritable impact sound, possbilits are immense.

But again this is not a metal zone. It's a vintage pedal rather dstine to, rock to pop, has what you want but certainly not metal.

To be more prcis: With this pedals means all notes of the chord with the jou even drive has pushed donf.


A marvel.

For fans of the Fulltone fulldrive.

It's really a great product.

I use it in my complment firebrust (fuzz) from the same manufacturer.

This is the J-Drive so MkIII Overdrive and / or booster. I remember for a nophytes overdrive is not a distortion or fuzz. Simulates an overdrive (how horrible word in this case) the heat lamps well stimulated.

There is a rglage the drive, one of the "heat" and a volume for the part and a simple volume overdrive for the boos, a small BRT switch, a switch to activate each effect indpendamment, an input e guitar output (yes fortunately) and a socket for power collection outdoor type Boss.

Food by my PCioks 9 volts AC in the Rider PDAL comes with a battery.


It's simple: you plug, turn the knobs and we seek happiness. Easy, normal, normal.

There is a manual trs express in English, but in fact that Arelle need? The ears are enough.

Some precision:
- The BRT switch for bright, turned on (position) allows the manufacturer to use the expression "to make them brighter or humbuckers to get that little more bite."
- The button "Warmth" is not just a filter "low cut" like most of the tone found on overdrive. It acts as a filter of "low pass" coupled with the gain of the drive. In short: the more you turn in the clockwise over the filter mounts frquence cutoff which gives the impression of more heat in the sound but at the same time the amount we gain more harmonic. It may seem complicated to some, but it's really much more effective than a Tone knob that simply cut the frequencies and signal altre gnralement the pedals.

However, rest assured the use is very simple, plug and ring.


Distos of overdrive and I have had several over the years, the one is really fantastic. I just hsit with Fulltone (brand I love) but my gnait c'tait the impossibility to use the boost indpendamment of overdrive. The sound is clear, organic, no pedals gnre no breath (although the overdrive always cre). In boost mode the sound of guitars (Fender Stratocaster and Heritage H 535) and are fully respects the amp, the sound is clear. The overdrive is "crmeux" hope and fully Ragit change in volume on the guitar. We can thus move from a lightweight crunch saturation with no major attack of the strings. It is a PDAL trs "organic" feeling that respects the guitarist and his intentions.


Diamond is a small Canadian company based in Halifax Dartmouth prs. Does she founded by two musicians (a guitarist and a bassist) who collected the pedals and amps for years. One of them is a specially ingnieur effects in acoustic and psycho-acoustics. Manufacturing hand and solid pedals that leaves no doubt on its reliability and strong. Each PDAL is wearing a serial number (mine is numro 179). Like Fuller (from Fulltone), when they are more reliable components for ncessaires couraging their effects, they shall adopt just the production, which is a guarantee of quality and srieux.

I had the opportunity to try their time limit (the Memory Lane) I found fantastic and I expect soon will integrate into my set.

Unlike the Ides reues on overdrive can Integrates perfectly into the pdalier a "mtaleux" insofar as she works as an amplifier and will be perfectly well nerv comfortable with a distortion or fuzz up ahead (between the J Drive and Wha Wha for example). Of course, the blues and rock is much suprieure IDAL and an Ibanez TS808 or Tubescreamer.

Some argue that its price is lev but the quality of pedals "boutique" is paid and if we compare with Jacques Overtube SERIES is manufactured in Poland, 30 of Difference drisoires are next to the quality. The question is, if we want to give his instruments prfrs partners height. For me the price is justified.

I love the pedals, if I was flying I would take the right away without another hsiter.

Finally, I'll just say that we find almost never occasion which means that guitarists who adopt it are satisfied and keep it.
