In January 1970 Led Zeppelin hit the stage of London's historic concert hall, Royal Albert Hall. At this performance Jimmy Page expressed 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 filled the entire hall with a cornucopia of colors at levels ranging from a mouse whisper to rave ups louder than a jumbo jet taking off only inches over your head.
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, meaning turning one can alter the behavior of the other. The magic is getting the Mid and Bass controls dialed in together. Tweak those until you get the right tone for your guitar and amp. You’ll notice that the Treble knob is fairly subtle, adding a bit of bite as it is turned up. If you scoop the Mid and turn up the Bass however, the Treble knob will seem a lot more active.
The RAH is designed to deliver guitarists an incredible dynamic range that responds to picking hand and/or volume knob. Like a good amplifier the RAH is VERY uncompressed, which means there is little to "hide behind". This pedal is for players who appreciate the rewards and experience of a WIDE dynamic response. Plug the RAH into a clean(ish) tube amplifer, leave the pedal on all the time accessing clean tones by rolling back your guitar's volume knob, or turn it on and off as your "gain channel". We're including a HERCO pick, use the nubby edge for chirpy articulation.
The MASTER controls output volume. For best response, set it just past unity volume - usually around noon. (Unity volume means the volume with pedal on is about the same as with the pedal off.)
The 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.
The three 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 affect the behavior of the other knob. Tone circuits like these are NOT active circuits designed to function like your home theater, car stereo or PA. Tone circuits like these are designed to provide fine tuning over the range of the guitar spectrum as well as being the actual voice of any specific amp.
