Originally designed as an integral part of each Pete Cornish Custom Pedalboard and Rack System, Pete’s Linear Boost allows a boost in volume, without any tonal alteration, to lift a player’s solo above the background sound level. It is important to note that for maximum linear boosting the unit should be connected just before the input of a clean amplifier and after any effects units. If the amplifier has a distorted (Lead) channel it would be beneficial to connect the Linear Boost after the preamp section and just before the power amp input (an effects loop in the amplifier may be the best way of achieving this). The BOOST footswitch on this unit is not a bypass switch; when the indicator light is OFF the unit acts as a unity gain buffer amplifier with high signal level capability and can drive long cables without tonal loss. When the indicator light is ON your pre-selected amount of boost (up to +27dB) will be available at the output of the unit. There is no tonal change or phase shift to the boosted signal.
In addition an isolated Tuner Feed is incorporated which sends a unity gain, mirror image of the guitar signal to a tuner. The setting of the Boost control and the position of the Boost and Mute switches do not alter the signal sent to the permanently active Tuner Feed.
The MUTE function may be activated at any time, whether or not the Boost is engaged, and will totally shut down the audio path to the main output.
FEATURES:
Four Functions: Line Driver, Linear Boost, Isolated Tuner Feed and System Mute in one convenient package: compact size 145x95x49 mm.
Each unit, housed in a Rugged Die-cast box is hand built, wired and tested by Pete, Lynda and Mingus Cornish.
Heavy Duty all-metal footswitches with Hi-Brite LEDs.
An input for a DC adapter is fitted: the size of the coax connector is 5.5/2.1mm and the center pin is negative (-VE). The voltage rating of the adapter should be noise free, fully stabalized at 9V DC and capable of supplying 20mA. We recommend the use of the Voodoo Lab pedal Power 2 Plus adapter as meeting the above criteria and cannot accept any liability for damage caused to this unit by the use of , or to, any other type of of AC/DC adapter. An adapter proving an output of an AC coltage should not be used as it will permanently damage the pedal: such damage is not covered under our warranty. If only a single unit is to be powered the BOSS PSA series may be more cost effective and is also recommended; but do not "Daisy Chain" other effects if using this adaptor as this may cause hum problems.
IMPORTANT NOTE:
This unit has now been upgraded to Dual Voltage. The voltage of the DC supply does not affect the Boost gain.
Using a 9vDC adaptor the performance will be as shown below left.
Using a fully smoothed and regulated AC/DC adaptor with an output voltage of 24vDC Maximum, and capable of supplying 20mA, the signal performance of the unit will be as show below on the right.
Please do not use an adaptor with a higher output voltage than the specified 24vDC maximum, or of reversed polarity, as it may damage the unit and such damage will not be covered under the terms of our guarantee.
An adaptor with an AC voltage output should NOT be used.
