The Flattley “Silver Range” Silver Centurion pedal is Flattley Guitar Pedals version of a very famous type of transparent overdrive pedal. This pedal is perfect to use on its own to get mild gain sounds that just starts to break up or go full tilt to get a full-on overdrive sound when your amp is set on the clean channel. Alternatively, you can use this pedal to boost an over-driven tube amp or overdrive, distortion, fuzz and muff pedals that will give an amazing sound, clarity and tone. This pedal also cleans up when you turn down the guitar volume without losing the overall volume levels so it is a very versatile pedal that can be used for many different types of applications.

Silver Centurion hints and tips:

The Silver Centurion is a transparent overdrive in the same way that a Klon Centaur is. Transparent means that it doesn’t drastically change the colour of your tone so when you turn the pedal on, it won’t sound like a different guitar tone. It will sound like the same tone, but better. My Strat is just “more Strat”… etc.

This is achieved by separating the frequency spectrum up into several bands and treating each differently. Bass frequencies are passed through untouched giving a full bottom end, treble frequencies also pass through but can be boosted by the tone control, mid frequencies go through a soft clipping circuit to give them an amplitude dependent boost to the harmonics. The gain control controls gain and volume simultaneously to vary the sensitivity and width of the mid band of frequencies.

The pedal also acts as a buffer when in standby which is an advantage if you use it as the first pedal in a chain of effects. This gives you two ways to use the Silver Centurion…

It can be used as a clean boost for your amplifier. A booster adds some extra girth to your signal to push your amp a little harder. Set up a clean tone on your amp and experiment with the pedal. Start off with a low drive level, then gradually build the pedal gain up as you play. You’ll learn how the pedal changes as you add in more gain. If you have a tube amp, you’ll be able to hear how the pedal also begins to push your amp at a certain stage.

You can also set your amp to the point where it’s on the verge of breaking up, then use the pedal to push the amp into overdrive. This is another common way of using a transparent overdrive pedal.

Another way to use a Silver Centurion is to stack it with other drive pedals. You can use a pedal (or your amp) to produce your main drive tone, then you can add in the Silver Centurion when you want your tone to have a bit more sparkle or boost.

The blue halo light ring installed diffuses the light when playing live, avoiding being blinded by the standard LEDs just as you are about to go into that all important solo thus giving a larger area to see where the pedal is located easily on the pedal board on darkened stages. The addition of the large aluminium foot topper gives you more real estate for contact when switching the pedal on and off during quick changes when playing live.

All Flattley “Silver Range” pedals are hand processed in our Flattley paint shop. They are etch primed first to ensure that the primer bonds to the aluminium enclosure which also provides an anti-corrosive protection layer. Multiple coats of base coat primer applied, the silver base coat colour is then applied and topped off with several coats of lacquer. Once the lacquer is hardened, it is then hand polished to achieve the smooth deep lustre finish that is inherent in all Flattley Guitar and Bass effects pedals. The graphics designed in house by our graphics designer Phoebe Flattley are applied to “Silver Range” effects pedals by UV direct printing in our printing shop.

    The Centurion is the overdrive pedal I spent years looking for. I use it as a boost to add that little something extra to my over driven amp. If I’m playing a lead or solo I can almost guarantee the Centurion is turned on.
    Great tone and top customer service from Flattley pedals.

    • Paul Flattley

      Hi Martin, thanks for the kind words on the Centurion pedal. The Centurion certainly adds that bit of magic to the FX signal chain when its on and its so versatile. Many thanks and best regards from Team Flattley

  2. Paul Turton

    The Centaur is one of two amazing pedals that I have, the other being the Helstonbury Muff. The Centaur works for me in so many ways, first of all it’s unique clarity and crunch it gives raises my sound profile, combined with pure enhancement and overall quality throughout. The crunch is variable through the GAIN pot, and because the make up of this pedal is so well made the sllightest adjustments is all that you need to get the sound you are looking for.
    Absolutely top pedal, top brand and all round quality product. hearing is believing ?

    • Paul Flattley

      Hi Paul, thanks for the amazing comments on the Centurion pedal and yes it just adds that magic to the signal chain. We’re delighted that you love your pedal and are using it as it was designed for. Many thanks regards Team Flattley

  3. Chris Saunders

    I’ve been using the Centurion for just over a year, as a light overdrive in places, but mostly as an ‘always on’ tone shaper. It adds a sparkle and presence to my clean sound that I’ve yet to find in similar veined overdrives. Really great as a boost into other overdrives to for that little bit of extra kick too!

    Great service from team Flattley from the initial order, all the way through to delivery!

    • Paul Flattley

    This pedal is absolutely stunning. It’s incredible. The quality and versatility is amazing. This is an exciting time where there are a lot of British based pedal builders coming through, but the guys at Flattley are definitely one of the leaders. Can’t say enough good things about this. Just go and order one, you won’t be disappointed.
