The controls for Spoiler electronics are: volume (usually nearest the pickups) low-pass filter frequency (nearest the edge) Q switch (next to the frequency) rotary pickup selector switch (teardrop knob) The frequency control adjusts a low-pass filter tunable from about 350Hz - 6KHz. Where you tune the filter is the cutoff frequency. Only frequencies below the cutoff frequency are passed. Q switch is on when you flick it down while playing. When the Q switch is on, it boosts the cutoff frequency of the filter by about 8dB. You can hear the effect by sustaining a note while rotating the filter back and forth with the Q switch is on. You should hear a distinct "wah-wah." You won't hear much affect if you flick the switch up and down while sustaining a note since the filter's influence is mostly on the attack of a note. Play a passage you are good at repeating well and try the same frequency setting with the Q switch on and off. Listen the start of each note to hear what the Q switch does. It's a subtle but musically useful control. You'll probably use the Q while slapping and playing rock. For blues and legato playing, you'll probably have the Q off. The rotary switch os a 4-position pickup selector. From the most counter-clockwise position, the settings are: 1. standby 2. neck pickup only 3. both pickups 4. bridge pickup only Note, the standby position is not the same as off. So long as you have a cable connected to the output jack, the battery is draining. The standby is useful for when you have an extended rest period but later want to return to your original volume setting. There is an onboard preamp, so the circuit is active and requires a 9V battery to operate. There is not enough output from the pickups to use them without a battery since they are low impedance. Internally, you will find 2 small trimpots on the circuit board that control the gain of each pickup. You can set the height of the pickups without regard to output. This means you can set the pickups' height to either where you like the way they sound or for your comfort, then go inside and correct the gains so that your pickup selector switch has the same volume for the neck and bridge pickups. |
