My Buying Guides on Pro Co Rat Distortion Pedal
Why I Consider the Pro Co RAT Distortion Pedal
When I look for a distortion pedal, I want something that can do more than just add gain. The Pro Co RAT stands out to me because it has a reputation for being versatile, durable, and capable of moving between distortion, overdrive, and even fuzz-like tones. I like that it has a simple control layout, which makes it easy for me to dial in a sound quickly without getting overwhelmed by too many knobs.
What I Look for in the Sound
For me, the biggest reason to buy a RAT is its tone character. I find that it delivers a gritty, aggressive distortion that still keeps note definition. It works well for rock, punk, grunge, and even heavier styles depending on how I set it. I pay attention to whether I want a more saturated distortion or a tighter, edge-of-breakup sound, because the RAT can cover both.
The Controls I Pay Attention To
The RAT usually comes with three main controls:
- Distortion: This is the gain control, and I use it to shape everything from light breakup to thick distortion.
- Filter: I see this as a tone-shaping knob. I turn it to tame harsh highs or open up the sound when needed.
- Volume: I use this to match my bypassed signal or push my amp harder.
I like pedals that are simple, and this one lets me focus on playing instead of constantly adjusting settings.
Build Quality and Reliability
When I buy a pedal, I want it to survive regular use, gigs, and travel. The Pro Co RAT has a solid metal enclosure, and that gives me confidence that it can handle life on a pedalboard. I also appreciate that it has a straightforward design, which usually means fewer things can go wrong over time.
How I Match It With My Gear
I always think about how a pedal will work with my guitar and amp. In my experience, the RAT pairs well with single-coil and humbucker guitars, though the tone changes depending on pickups and amp settings. I find it especially useful with clean or slightly driven amps, where it can become the main source of distortion. If my amp is already heavily distorted, I use the RAT more carefully so the sound does not get too compressed or muddy.
What I Check Before Buying
Before I decide to buy, I usually consider:
- Whether I want classic RAT-style distortion or a more modern high-gain sound
- How much control I need over tone shaping
- Whether I prefer a simple pedal with few controls
- If the pedal will work well with my current amp setup
- My budget and whether I want a standard or special version
