ASHDOWN ORIGIN

VALVE PRE AMP PEDAL

The OriginAL beautifully shapes the bass player's clean signal whilst offering a foot-switchable

valve powered overdrive in a single compact unit. Crystal clear cleans and powerful overdriven

growl, The OriginAL encompasses it all.

Setting the Level

The -3db Pad switch is used in conjunction with the input level control to suit the instrument in use,

Low output basses will not require the use of the Pad but Higher Output basses may overload the

pedal and require use of the Pad. Overloading the Input will simply create unwanted distortion

and sound unpleasant, with experimentation the correct settings will be found for the Instruments

you have.

Real Valve Overdrive

The Valve overdrive circuit fitted into the Original pre amplifier duplicates the kind of overdrive

you would get from Valve Amplifier and works in exactly the same way as follows,The DRIVE GAIN

controls the magnification of the signal from the instrument, at higher settings the Valve will be

overdriven clipping and compressing the sound from the instrument, Higher harmonics and

higher frequencies will be accentuated whilst the lower frequencies will be compressed. Just as in

a valve amplifier this will be accompanied by a drastic increase in volume dependant entirely on

the setting of the gain control.

To enable you to match the Overdriven signal level to the clean level a Drive level control is also

provided. In this way it is therefore possible to change from a crystal clean sound to an overdriven

sound of similar level. The Input Level control also has some bearing on this as it sets the starting

point from which the overdrive circuit works so some experimentation with this in conjunction with

Drive Gain and Drive Level will be required to get exactly the results you are looking for.

The OVERDRIVE is foot switchable and the pedal lights up blue when the overdrive is engaged.

When using the footswitch it is advisable and desirable to avoid large increases in volume as

sudden level changes may produce switching noise further down the line.
