Catalinbread RAH
What inspired the design and production of the Catalinbread RAH?
In 1970 Led Zeppelin hit the stage of London’s historic concert hall, Royal Albert Hall. We were inspired by a friend to capture the RAH performance in a pedal.
At this performance, Jimmy Page was expressing himself masterfully with a broad pallet of tones and GIANT dynamic range.
Of course, this has a lot to do with Page’s playing technique and Gibson Les Paul.
His backline amps, custom Hiwatt heads into Marshall cabinets, were filling the entire hall with a cornucopia of colours. Volume levels were ranging from a mouse whisper to louder than a jumbo jet taking off.
Royal Albert Hall sound in a pedal?
Catalinbread loves the RAH performance, but we hadn’t considered the possibility of capturing it to put into a pedal.
Our friend Charlie got hold of Catalinbread’s chief circuit designer Howard Gee to ask if we could do it.
Charlie said that he’d been trying to get this tone for years. He told Howard if anybody could do it would be Catalinbread.
Having proven his ability to capture the essence of famous amplifiers, Howard began experimenting with what is now the RAH.
The Catalinbread RAH features
This overdrive effects pedal features the specific three-knob tone circuit straight from the custom “Jimmy Page” model Hiwatt.
Like most traditional amp EQ circuits, the knobs are interactive, because turning one can alter the behavior of the other.
The magic is getting the Mid and Bass controls dialed in together and tweaking those until you get the right tone for your guitar and amp.
Your virtual pre-amp
The RAH delivers guitarists an incredible dynamic range, responding to picking hand and/or volume knob.
This pedal is for players who appreciate the rewarding experience of a WIDE dynamic response.
Plug the RAH into a clean(ish) tube amplifier and leave the pedal on all the time, so access clean tones by rolling back your guitar’s volume knob, or turn it on and off as your “gain channel”.
Think of the Catalinbread RAH as your virtual pre-amp and let’s think of your actual guitar amp as your “power amp”.
With that in mind, what types of pedals do most guitarists normally plug into the front of their amp? “All Pedals!” is the quick answer. But some types of pedals might work better in the effects loop of the amp or even fed from the amp mic.
So, pedals that you would normally plug in front of an amp, you’d plug in front of the RAH. Pedals that you might prefer to run in the “effects loop” would go between the RAH and your amp.
Overdrive was inspired by the 1970 Royal Albert Hall performance.
Authentic 3 knob tone stack from the “Jimmy Page” Hiwatt.
Designed to give an incredible dynamic response with your pick attack and your guitar’s controls.
Includes a Herco pick for chirpy articulation.
Technical Specifications:
2.34″ x 4.39″ pedal
Battery operation or 9v Negative Tip DC Power
4 mA draw
Controls:
First, you will notice three tone controls, Treble, Middle, and Bass.
These three tone controls reproduce the circuitry from Page’s Hiwatt exactly down to the component value.
They, like most guitar tone circuits, are highly interactive so adjusting one control will affect the behavior of the others. We’ll talk about the tone controls more later, but the important point is that they reproduce the actual circuitry from Page’s Hiwatts.
Its gain levels are perfect for using a humbucker-equipped guitar to get Page’s sound from the Royal Albert Hall show.
But, don’t think this pedal is only for playing Zep covers. Be inspired by its tone and response to write your own epic riffs!
MASTER
Controls output volume. For the best response, set it just past unity volume – usually around noon. (Unity volume means the volume with the pedal on is about the same as with the pedal off.)
GAIN
Control corresponds to the “Input Volume” control on the actual Page amp. The sweet spot for this control is from 3:00 to max for the best Zep-like response. But for a cleaner response or if your guitar has really hot pick- ups you may want to try lower gain settings.
TONE
Controls represent the exact circuitry of the Jimmy Page Hiwatt and will act the same and provide the same tonal response.
As with most “passive” amp tone circuits, the three controls are highly interactive – changing the setting of one may
