1988 ProCo RAT (LM308) | Gain Appreciation

This 1988 ProCo RAT is perhaps my favourite pedal. It's got some filthy stack-like distortion sweetened by the limitations of its iconic LM308 opamp.

When you want boost, overdrive, heavy distortion, and fuzz, the Rat does all!

I’ve loved this guitar channel for years but just know this pedal also has infamy in the acid genres of electronic music!!

[wildbilltexas]

It's showing its age but still an iconic pedal. The rep of the RAT was it could make a shitty sounding amp sound great.

Watching this while sitting next to my Rat pedal that I got for $20 from my guitar teacher: probably the best deal I’ve ever made in my life. The absolute best doom metal pedal.

Man the rat is an iconic pedal that guitar players are fond of. Some metal and rock hits have this pedal as the go to distortion unit.

I've always wanted to try a rat because Josh from jhs said it's one of his favorite pedals, and because it's like a fuzz distortion which is cool

[KentuckyWindage]

I might be kind of an oddball in this, but I use my Rat for blues and blues rock. A strat into a Rat into about any 6v6 amp will give you some of the thickest, meatiest tone you could ever hope for.

Got a 1991 LM308 Rat, is all you need in life

[SteveSchuffert]

Still have my 86 Rat, used on Texas leg/ opening dates on the Metallica master of puppets tour when I was with the Godz.

The Rat is great for when you just gotta let 'er rip.

I use a JCM900 MkIII with the first - only the first - preamp gain section all the way up. I have a volume pedal that drops the levels for "clean" sounds, which also conveniently allows distortion pedals to play nice with the preamp. I've noticed that this tends to blend the sound of the pedal with the trademark Marshall splatter fart. The Rat, with all of its nastiness, sounds particularly glorious in this setup.

I love the RAT. I don’t have one anymore but I have the EQD Life pedal which is basically the same thing but with a added MOSFET boost. THICCCC nasty tones are best suited for the pedal I love it! Great video as always Colin!

[cowsaysmoo]

I've always hated the fizziness I get out of literally any distortion pedal/high-gain amp I get my hands on these days. I usually low-pass to try to mend the issue, but it's not an ideal fix. I really want something like this that is physically incapable of producing that fizziness in the first place. It sounds absolutely incredible

[jasonwotring]

I just got one in yesterday. I'm loving it so far

[EpicStuffMan]

I love the rat, but for bass as well. It's magical, gets everything from light rock grit to full on grind.

[alexs]

Always love the videos mate, feel like I’ve taken a crash course in electrical engineering learning about the chip. Thanks for the high quality content!

[marcioastorpooter]

Thank you so much! I had to substitute the speaker of my 20-year-old Marshall solid state amplifier, but the new modern speaker was sounding like a full bee hive! With the information that you gave in this video, I built a low pass filter to cut everything above 5khz. It's amazing now. Like it used to sound with the original speaker but with lots of extra bass! Not muffed at all!. Your channel is one of those where you find really good information on Youtube!

[michaelcottle]

Great video, loved the mixture of academic explanation and demonstration. More like this please!

[OddTimeMan]

I've always loved the sound of that pedal. Loved it back in the late '70s, loved it throughout the '80s, and still love it to this day.

[jameskaihatu]

This is an exceptional explanation of a pedal I own and haven't quite figured out why I like as much as I do. Thanks!
