Epiphone Bass Guitars

Instruments with active tone controls have a powerful circuit within them. This circuit requires power from a 9V PP3 battery in order to function. The Epiphone Toby Deluxe IV is one of these instruments. There is normally a compartment built into the back of the instrument to facilitate this. What you get is a set of 'active' tone controls which can cut and boost frequencies with far more power and precision than normal passive controls. These are very useful features to have in order to dial in the exact tone you want. The power to this circuit is switched on automatically when you insert your input jack lead. Remember to pull out your cable when you finish playing or you'll run down your batteries very quickly!

The switch on the Epiphone Jack Casady bass is a VariGain switch. This three position switch allows you to alter the sound and output levels according to intended use. The three settings refer to ohmage. The '50' setting is perfect for a balanced DI sound. The '250' setting is great for fattening up the sound for hot blues and rock sounds and the '150' setting lies somewhere between the two. It is a passive switch, requiring no batteries to power it.
