Педаль Drive с ламповым предусилителем ASHDOWN FS-ORIGIN-VALVE-PRE

The OriginAL beautifully shapes the bass player’s clean signalwhilst offering a foot-switchable valve powered overdrive in a singlecompact unit. Crystal clear cleans and powerful overdriven growl, TheOriginAL encompasses it all.

Setting the Level
The-3db Pad switch is used in conjunction with the input level control tosuit the instrument in use, Low output basses will not require the useof the Pad but Higher Output basses may overload the pedal and requireuse of the Pad. Overloading the Input will simply create unwanteddistortion and sound unpleasant, with experimentation the correctsettings will be found for the Instruments you have.

Real Valve Overdrive
TheValve overdrive circuit fitted into the Original pre amplifierduplicates the kind of overdrive you would get from Valve Amplifier andworks in exactly the same way as follows,The DRIVE GAIN controls themagnification of the signal from the instrument, at higher settings theValve will be overdriven clipping and compressing the sound from theinstrument, Higher harmonics and higher frequencies will be accentuatedwhilst the lower frequencies will be compressed. Just as in a valveamplifier this will be accompanied by a drastic increase in volumedependant entirely on the setting of the gain control.

Toenable you to match the Overdriven signal level to the clean level aDrive level control is also provided. In this way it is thereforepossible to change from a crystal clean sound to an overdriven sound ofsimilar level. The Input Level control also has some bearing on this asit sets the starting point from which the overdrive circuit works sosome experimentation with this in conjunction with Drive Gain and DriveLevel will be required to get exactly the results you are looking for.

TheOVERDRIVE is foot switchable and the pedal lights up blue when theoverdrive is engaged. When using the footswitch it is advisable anddesirable to avoid large increases in volume as sudden level changes mayproduce switching noise further down the line.

Power Supply
The ORIGINal Pre-amplifier requires aLinear Isolated High quality Regulated power supply that can supply acurrent 300mA at a voltage of 15-18V DC Centre Pin NEGATIVE for thefitted 2.1mm connector socket. Since most Professional pedal board powersupplies have outputs at 9V and 18V the pedal is marked at 18V. Thepedal reduces the incoming power supply down to 12v suitable to drivethe Valve and internal circuits, for the internal stabilisation to befully effective the connected power supply should be between 15-18V DCas stated…
