7. 2 seconds Some helpful hints We have given you model specific tone controls They react as the actual amp would in a given situation For instance turning the treble up all the way is a very different experience on each model We would suggest that you pull up an amp and start with these controls at 12 o clock and the drive down then decide what you want to hear from there If you want more low end ask yourself if you want more round thick low end or do you want punchy low end This will help you determine if you should add Bass or Low Mid to your sound Sometimes adding Low Mid gives you the bottom you want with a punchier sound The same goes for the high end Are you looking for clarity for your note or a percussive attack If you want clarity many times Hi Mid will give that to you without adding the percussive attack Experiment with the tone controls because we have given you a range of tone that has never been available in a combo before Drive This control is used to overdrive the preamp in order to get various distorted sounds In the fully counter clockwise position is the cleanest least distorted sound and as you turn it clockwise you bring in distortion Adjust to your taste Tone Controls Bass Low Mid Hi Mid and Treble controls are customized for each Amp Model to give you optimal tonal control These controls will help you to shape the tone you hear in your head Opto Comp The compressor control adjusts
