Cornerstone Gladio Overdrive - Guitars Rebellion

The Cornerstone Gladio is a typical "amp like" 2-channel pedal. This one is inspired by the amps created by Howard Dumble. A term widely overused by 99% of amp and pedal manufacturers around the world, the "Dumble" sound is generally associated with a very fluid, warm drive sound with lots of sustain. This one having the originality to have a very particular articulation which allows it to remain perfectly audible through the mix. There are as many different sounds as Dumble made, but that's generally the current widely held consensus.
Widely used by guitarists like John Mayer, Robben Ford, Stevie Ray Vaughan, Joe Bonamassa and more...the Dumble sound has become a benchmark for all tasteful guitarists.

Externally, the pedal adopts a "brushed" case of the most beautiful effect (yes!). It is 100% machined "in house", from cutting to drilling. We are in the usual "boutique", with very good quality PCBs, selected components and a pedal that will take the worst treatment. 2 channels, 1 Gain, 1 Volume, 1 Tone per channel with 2 toggle switches and the possibility of combining or not the two channels via the central switch.

Let's not cut corners, if you want to get the best out of the Gladio, you need an excellent Two-Rock channel, just like its competitors King Tone Guitar The Duellist or VS Audio Royal Flush . Reference configuration, the circuit of the Gladio hides a TS + BB that can be found on most similar "Dual" pedals, each going with its own little secret modification. Once plugged in with a Tom Anderson Icon Classic in hand, you activate Channel 1 which delivers a fluid, soft, fairly high medium drive. This one offers a very nice dynamic and avoids the medium "corner corner" of most pedals of its kind. The attack is frank, the drive bends when you go inside. It can also serve as an excellent boost and the EQ couldn't be more responsive. Channel 2 running in parallel adds sharpness, bite and more harmonics. When you combine the two, you get a headroom that will cover almost any style (except extremes). The 2 toggle switches increase the versatility of the Gladio. The Jazz / Rock switch remains effective. The Rock position brings more brilliance and a forward midrange, where the Jazz position offers a more subdued, softer finish. Big highlight, the Comp switch which allows you to really modify the dynamics of the pedal. The position will be chosen mainly according to the level of gain. We prefer to add compression when it is high, and remove it when using the pedal as a Boost. Personally, we used the active position a lot, which brings a very pleasant "squashy" side.

With the Gladio "Dual", the Italian brand poses as a serious competitor to the King Tone Guitar The Duellist. The two pedals are very similar, but we can guide you by telling you that the Gladio is a little more compressed and "straight", where the Duelist is a little more open and soft. An excellent pedal that has established itself as one of the references of its kind.
