The Ampeg Classic Analog Bass Preamp pedal is like having a choice of Ampeg amps right on your pedal board. Dial in a wide range of authentic Ampeg tones with the 3-band tone stack and highly flexible Ultra-Hi and Ultra-Lo circuits. It’s the most affordable way into the pure analog bass tone of Ampeg.

Like all Ampeg products, your Classic Analog Bass Preamp pedal is designed by musicians and built using only the best of components. Each pedal is tested to confirm that it meets our specifications, and we believe that this pedal is the absolute best that it can be.

1.INPUT: The signal output from an instrument (active or passive) may be connected to this 1/4" Input by means of an unbalanced, shielded instrument cable.

NOTE: There is a –15 dB Pad Jumper located inside of the pedal. Details on switching the jumper may be found on page 5.

NOTE: Unplug the input cable when not in use, as the 9V battery will drain (and eventually die). Details on replacing the battery may be found on page 5.

2.CLASSIC PREAMP SWITCH:

Engage this switch to activate the Classic Preamp pedal. This pedal is true bypass, meaning the signal will pass through from input to output, with no circuitry in between, when the switch is disengaged.

3.ON/OFF LED: This LED illuminates purple when the pedal is engaged.

4.VOLUME: Use this to control the overall output level. Use it wisely and turn it down when making connections or trying something new. Unity is at 12:00.

NOTE: The Volume control is active only when the pedal is engaged.

5.BASS: Use this to adjust the low frequency level. This provides up to 7 dB of boost, or 20 dB of cut, at 40 Hz. The low frequency output is flat at the center position.

6.ULTRA LO: This switch, when engaged, enhances the amount of lowend output with a 2 dB boost at 40 Hz, and –10 dB cut at 500 Hz.

7.MID: Use this to adjust the midrange frequency level. This provides up to 5 dB of boost, or 11 dB of cut, at 500 Hz. The midrange frequency output is flat at the center position.

Rotate the control counter-clockwise for a “contoured” sound, (more distant, less midrange output) or clockwise for a sound that really cuts through.

8.TREBLE: Use this to adjust the high frequency level. This provides up to 10 dB of boost, or 10 dB of cut, at 4 kHz. The high frequency output is flat at the center position.

9.ULTRA HI: This switch, when engaged, enhances the amount of high-end output by 7 dB at 8 kHz.

10.OUTPUT: Typically, this 1/4" Output jack connects to the input of an external power amplifier – or powered loudspeakers, as long as they have their own input controls to adjust the volume level – by means of an unbalanced, shielded, instrument cable.

However, it may alternatively be connected to an external mixer, recorder, or interface. In this way, you do not have to mic the speaker cabinet in order to add it to the main mix or to record. The level of the signal is affected by the Volume control when pedal is engaged.
