Using the Switchblade Pro is quite simple. First, connect it to your guitar, amps, and other instruments according to your needs. You can switch between two amps just by pressing the relevant buttons. To set up effects loops, you can choose between series and parallel modes. In series mode, you can also control the order of the loops. If you're a multi - instrumentalist, connect up to three instruments to the pedal and then to one amplifier. You can mix the sounds of these instruments and adjust each volume separately. For bass players, use the Dry Level control to get the right sound. When it comes to maintenance, keep the pedal in a dry and clean place. Avoid exposing it to extreme temperatures. Also, make sure to use the included EHX 9.6VDC - 200mA power supply to prevent any damage. When you're not using vintage, non - true bypass pedals in the FX loops, you don't have to worry about tone - suck. Just remember to handle the pedal gently as it's a precision device.
