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.


Four Functions: Line Driver, Linear Boost, Isolated Tuner Feed and System Mute in one convenient package: compact size 171 X 121 X 55mm.

Each unit, housed in a Rugged Die-cast box is hand built, wired and tested by Pete and Lynda Cornish.

Heavy Duty all-metal footswitches with Hi-Brite LEDs.

Easy battery replacement via a removable ‘drawer’. The battery is switched on when you insert the “INPUT / PWR ON” jack and to ensure long battery life unplug this lead when the unit is not in use. If the unit is not to be used for a long length of time we recommend that you remove the battery. Preferred battery type is MN1604.

Also fitted is an input for a DC adaptor: the size of the connector is M2.1 and the tip is negative (-VE). The voltage rating of the adaptor should be fully stabilized at 9.6V and capable of supplying 20mA. We recommend the use of the BOSS PSA series adaptors (PSA-100/110/220 or 240 depending on your local AC supply voltage) as meeting the above criteria and cannot accept any liability for damage caused to this unit by the use of any other type of AC/DC adaptor.
