This pedal gives you two different drive sounds in one box, which is great for live sets. You can swap between a warm Germanium feel and a punchier MOSFET tone using the Clip knob.

Pros
- Two separate drive channels let you mix sounds easily
- Switchable Germanium or MOSFET diodes for distinct tone
- Bright switch adds extra treble without changing the core sound
Cons
- No battery option means you need a wall adapter always
- Power adapter is not included and must be bought separately

Pros
- Smooth creamy tone on Channel 1
- Aggressive hard clipping on Channel 2
- Realistic Dumble tube amp saturation
Cons
- No specific weight listed
- Limited tone shaping controls

How to choose the best distortion pedals
Heritage & Voicing
Cornerstone's design philosophy draws heavily from classic British distortion - think early Marshall stacks, but with refinements. They're not trying to recreate a specific amp exactly, but capture that essence of thick, responsive distortion, often with a mid-focused character that helps guitars and basses sit well in a mix.
Dynamic Response
This is where Cornerstone really shines. They respond incredibly well to your pick attack and volume knob adjustments. Subtle changes in your playing translate into nuanced shifts in distortion level and character, avoiding that flat, one-dimensional sound so common in cheaper pedals.
Midrange Focus
While you can dial back the mids, Cornerstone pedals tend to have a natural emphasis in that critical 500Hz-1kHz range. This is essential for cutting through a wall of guitars or bass in a live setting, and it provides a solid foundation for stacking with other effects. It's not a harsh, nasal midrange; it's that fat midrange honk that gives your tone authority.
Build Quality & Components
These aren't boutique pedals priced through the roof, but they don't skimp on the fundamentals. Solid enclosure, quality pots, and a good selection of components - they're built to handle the rigors of gigging. The footswitches are reliable, and the jacks feel robust, which is more than you can say for some pedals costing twice as much.
Versatility
While rooted in British distortion, Cornerstone pedals offer surprising versatility. They can cover a wide range of tones, from subtle overdrive to full-on saturated distortion, and they play exceptionally well with a variety of amps - from clean Fender platforms to high-gain tube amps.
Buying guide
Alright, let's talk about distortion. You're not chasing a sterile, fizzy breakup - you want something with character, something that'll cut through a live mix or add grit to a layered recording. Cornerstone pedals have been quietly building a reputation for nailing that sweet spot between vintage vibe and modern flexibility, and they're worth a serious look if you're tired of the usual suspects. These aren't just distortion boxes; they're tone shapers.
Cornerstone pedals aren't the cheapest distortion on the market, but they offer a serious bang for your buck. You're paying for a thoughtfully designed circuit, quality components, and a tone that's both authentic and adaptable. Don't expect pristine, surgical tone shaping - these are about feel and character, and they're best suited for players who value responsiveness and a vintage-inspired vibe over hyper-precise control.
If you're chasing a sterile, compressed sound, look elsewhere.

Questions
Are they true bypass?
Yes, all Cornerstone pedals feature true bypass switching, ensuring your signal remains unaffected when the pedal is disengaged. This is important for preserving your amp's natural tone and avoiding unwanted noise.
Can I use these with a bass?
Absolutely! While marketed for guitar, the midrange focus of many Cornerstone pedals works surprisingly well with bass. You'll get a lot of low-end thump and definition without losing clarity. Experiment with EQ to dial in your desired tone.
Do I need a high-end amp to get the most out of them?
Not necessarily. They sound great with a variety of amps. However, a decent amp with a clean headroom will really let the nuances of the pedal shine. A cheap, fizzy amp will just amplify those issues.
Can I stack them with other pedals?
Definitely. They play exceptionally well in a pedal chain. Try stacking a Cornerstone overdrive with a fuzz for a thick, layered sound, or use one for a subtle boost and another for heavier distortion.
What's the difference between the [Specific Cornerstone Model 1] and the [Specific Cornerstone Model 2]?
The [Model 1] leans more towards a classic Marshall-esque overdrive with a bit more bite, while the [Model 2] offers a smoother, more saturated distortion with a slightly warmer low-end. It's really about personal preference - both are excellent pedals.
