I often get the question “which overdrive and/or distortion pedal covers most of David’s tones?”. Naturally the answer will depend on which tone or era you prefer but if you’re only looking for one or two pedals that can do it all I recommend the Maxon OD808 and the ProCo RAT.

Now, neither the RAT nor the Overdrive 808 (or Tube Screamer 808) are overly exciting tone wise. People who swear by their Cornish or an original “triangle” Big Muff may find them a bit bleak or something they’ll use at home (I guess I’m one of them). Still, what made these pedals legendary were guitarists like Steve Ray Vaughan, Jeff Beck, Carlos Santana and David Gilmour. To me these two pedals sounds just like what a distortion and overdrive should sound like. No thin, fuzzy overtones or treble that will cut you in half. Just a smooth, warm tone suitable for any musical style.

The Fuzz Face, Big Muff and Colorsound Power Boost were designed to drive the hell out of a clean tube amp like Hiwatts and Sound City. The more gain you added the more gain you got from the tubes and the combination made the pedals silky smooth with a sustain that would last all night long. This is hard to achieve when you’re sitting at home with neighbours all around and playing on a small transistor amp. The RAT and Overdrive/Tube Screamer was designed with the intention of capturing the sound of a naturally saturated tube amp without having to blow your head off. They sound great at home on your little amp and awesome on stage with your tube stack.

The Maxon OD 808 Overdrive
The Japanese company Nisshin Onpa started making guitar pedals in the mid 70’s and issued them under the name Ibanez outside Japan. At the same time they sold the same pedals under the name Maxon in Japan. After Ibanez and Nisshin parted ways in early 2000, Maxon is now available in most countries and have specialized in reissuing the old Maxon line from the late 70’s. In short terms, the Maxon OD808 is the same pedal as the Ibanez Tube Screamer TS-808.
The Overdrive/Tube Screamer was introduced in the late 1970’s and soon became the most popular overdrive unit of all time. The tone is often described as the mother of all overdrives and every overdrive unit made since by any company seems to have been based on this pedal.

Compared to a Colorsound Power Boost the Overdrive/Tube Screamer has a much more modern sound with a smooth, warm tone and a distinct mid range. It ranges from clean boost to a fairly mild classic Marshall Plexi overdrive.

The Overdrive/Tube Screamer is also great for boosting a distortion unit like a Big Muff or the RAT just like David is using the Colorsound Power Boost and the Tube Driver.

David and the Overdrive/Tube Screamer
Ideally I’d go for two overdrives in a Gilmour setup. One vintage sounding with a transparent, glassy tone for the 70’s (Colorsound, Boss BD-2 etc) and one modern sounding with a warm, smooth mid rangy tone for the 80’s, 90’s and present. Still, the Overderdrive/Tube Screamer will cover any Gilmour era with some tweaking. By setting the tone control on the pedal fairly bright you’ll get a tone similar to David’s on typically Money, Have a Cigar and Pigs. With the tone control rolled down for a warmer slightly more dirty tone it will sound very much like a Cornish SS-2 or the Tube Driver on songs like Coming Back to Life, Shine On and Another Brick in the Wall (part 2) from PULSE.

David used an Ibanez TS10 on the 1988-90 leg of the Momentary Lapse tour.

Which one to choose
As mentioned, the Maxon OD808 and the Ibanez TS808 are identical. The original first editions are hen’s teeth among collectors but both are recently reissued with original specs and parts.

Originals
Maxon OD808, Ibanez TS808 and TS9.

Boutiques and clones
BYOC Overdrive, Robert Keeley TS9 and TS808 Mod Plus, Voodoo Lab Sparkle Drive.

Budget
BBE Green Screamer, Ibanez Tonelok TS7, Digitech Bad Monkey, Behringer TO800

The ProCo RAT
The RAT was introduced in 1979 and originates from modifying Fuzz Faces for more gain and a generally better tone. Like the Overdrive/ Tube Screamer the RAT soon became one of the most popular distortion pedals ever made.

The tone is very much like having a germanium Fuzz Face boosting a Marshall Plexi with a distinct mid range added. It ranges from near clean to overdrive to compressed distortion. With the distortion control slightly rolled off the RAT is an excellent overdrive pedal and the many mods have utilized this making it an extremely versatile pedal.

Although the RAT sounds great alone it’s recommended to use a booster behind it or an EQ pedal to boost the bass and volume for a bit more attack and balls.

David and the RAT
As with the overdrive, I recommend having two distortion units in your Gilmour setup, – one fuzz unit for the pre-Animals era and one Big Muff for anything from Animals to present. However, the RAT is capable of producing wild fuzz tones and silky smooth Big Muff tones. With the filter/tone control at about 12:00 and the distortion and volume control at 3:00 you’ll get a bright fuzz type of sound. With all the controls at around 2:00 you’ll get a warm, smooth Big Muff sound. This sounds even better with the Overdrive/Tube Screamer (or any other booster) behind it.

David used a RAT II on the 1988-90 leg of the Momentary Lapse tour and again on the Division Bell tour 1994. The pedal is also seen used on both the sessions for the La Carrera Pan America soundtrack in 1991 and for the Division Bell recording sessions in 1993-94.

Which one to choose
I have the “vintage” or first edition RAT. This is no longer available but it pops up frequently on Ebay. The RAT II has a bit more gain and bass than the “vintage” RAT.

Originals
ProCo “vintage” RAT and RAT II.

Boutiques and clones
BYOC Mouse, Robert Keeley RAT mod, Absolutely Analog Ratzo and Hartman Distortion.

Budget
I haven’t been able to find a good sounding budget model of the RAT. The ones listed above should be affordable for most budgets but if you have some suggestions then please share it in the comments field.

So there you have it. I consider these to be the R2D2 and C3PO of my collection. They belong together. I sometimes forget them and use only my Big Muff or fuzz but then I plug them in it’s meeting good old friends for the first time in years.
