Description

Gladio SC (single channel), is designed to offer the same sound of the "big brother" Gladio but in a smaller and compact size.

While the Gladio double channel was inspire by the artists like Robben Ford and Sonny Landreth, the Gladio SC tries to take a step closer to the Steve Ray Vaughan sound, which was achieved using a Dumble amplier too.

The Gladio SC is based on the Gladio 1st channel, with the exact same sound and controls, except the new CLEAN knob. This addition makes a very big dfference, and it's the one that could actually make the sound be closer to SRV.; the clean signal is taken directly at the input of the pedal and mixed back with the overdriven signal at the output, the CLEAN knob thus manages the volume of the clean signal. with the result of having a "clean layer" on top of the overdrive sound, which help a lot to achieve that texas-blues sound.

A Clean knob like this affects 3 parameters all at once (you can notice their change sweeping the Clean from zero to even a 40% rotation): - Bottom End: the sound becomes fatter - Compression: The non-compressed clean sound comes into the mix, and the change in compression is particularly accentuated on the attack. - Saturation: When the clean sound comes into the mix the final output sound becomes hotter, and it’s able to better push the front end of the amp.

Critic Reviews

Cornerstone Gladio SC review: The most pedalboard-friendly Dumble pedal around?

guitar.com

The Cornerstone Gladio SC is a compact powerhouse that delivers high-class, Dumble-inspired tones, making it a standout option for pedalboard enthusiasts. Its innovative Clean control allows for a versatile blend of clean and overdriven signals, effectively transforming your amp's character. With its elegant build and impressive tonal clarity, it caters well to various styles, from bluesy leads to punchy Texas tones. However, while it excels in many areas, the pedal's price point may be a hurdle for some, and it may not fully replace a true preamp experience for purists. Overall, this pedal shines as a smart investment for those seeking quality overdrive in a small form factor.

Amazing

It’s supposed to be a Dumble overdrive. I’ve never played a Dumble, so I can’t really tell. What I can tell though is that this is an amazing pedal, really open, with treble to fall in love with, clean blend to retain as much clean signal you want in, lot’s of gain if needed. Works great as a pre-amp to push another drive (or amp), or as the main drive (with a pre-amp/boost before it). Love it.
