Operating instructions

Begin with the frequency control fully counterclockwise. Turn the Level 
control to approximately 9:00. Now, while playing, rotate the frequency 
control to the right a little at a time. You should be able to easily hear the 
frequencies this first set of controls affects. 
Now, cut the Level control to approximately 3:00 and do the same thing. 
Here are a couple of tips to help you dial in your desired tone: 
For a great fretless tone, dial in a little extra at approximately 550Hz. 
For extra grind for Rock and other aggressive music, add a little at 1-1.2KHz 
or 2-2.2KHz. Remember, though, that a little goes a long way. Don’t over 
boost. 
NOTE: Remember that the tone you get when playing alone may not cut 
through as well as you’d like when playing with others. You may need to 
adjust the tone controls to achieve the same (apparent) tone, especially in the 
mids and high end. 
Edge Control – If you want to add a touch of old-school style grit to your 
sound, this is the control for you. This is not a full-shred type of distortion, 
however. Rather, it is mean to add a little, well, edge to your sound. This 
control interacts with the Input Gain; the effect will be more noticeable at 
higher gain settings. At lower gain levels, the effect will be very subtle. We 
recommend you spend some time experimenting with this Really Neat 
Feature. 
A FEW TECHNICAL THINGS TO REMEMBER 
Clipping = Bad – Keep an eye on the EQ Clip light. If it blinks, either 
reduce Input Gain or cut back on one or more EQ ranges. As we said earlier, 
Clipping in the preamp section is a Very Bad Thing and is to be avoided at 
all times. If you find yourself running out of amplifier headroom, cut a little 
in the lower frequencies, which require the most power from your amp. 
You’ll know this is happening if you see the Limit light flashing. As long as 
the light is just blinking, you’re fine. But, if it’s on more than it’s off, you 
might want to back off a bit. 
Frequency Oddities – Two areas are a frequent source of frustration for 
bassists trying to achieve their sound: frequency masking and frequency 
enhancement. Frequency masking occurs when other instruments
