Piccolo Bass Amplifier

Introducing the new Piccolo Bass Amplifier. Piccolo is designed to deliver world-class sound whether you're playing stadium rock or smoky jazz. A finely tuned 4-band EQ gives you the power to sculpt your tone for any room, any style. And, with up to 550+ watts of pure power, you can push multiple speaker cabinets to fill any space with warm lows, biting mids, and soaring highs.

Piccolo packs more professional features into its portable, 4.5 pound frame than any other amp, like an effects loop, voltage selector*, active/passive input, and a powerful mid-cut you can activate with a foot switch to bring out that killer slap tone right when you need it. And Piccolo features our critically acclaimed Vintage Tone circuit. Turn it on and an analog tube emulator rounds the edges and warms your sound for that quintessential 70's tone. 

Front Panel

Controls the volume of the signal passing through the EQ stage. To set perfectly: continually play your loudest, lowest note. Turn the Gain knob clockwise until the green light begins to turn orange/red as you attack the note. Now slowly turn the Gain knob counter-clockwise until the note you're playing produces only the occasional flash of orange. Leave the gain there and control your volume with the Master Volume knob.

Mid Cut Switch
Activates Mid Cut EQ. Green light is on when active. Expertly tuned for the perfect scooped-mid slap tone. 

Mid Cut Level
Provides up to 8 dB of cut @ 800 Hz. To set perfectly: set knob at 12 o'clock position. Activate the Mid Cut using the switch or optional foot pedal. Boost or cut in small increments by turning the knob clockwise or counter-clockwise.

Active/Passive Switch
Provides a 10 dB boost for passive basses. Reduces output signal of active basses to avoid unwanted distortion.

Input Jack
Connect your instrument using a standard 1/4 inch instrument cable. 

Master Volume
Controls the overall volume of the amplifier. Ergonomic shape makes it easy to see and adjust on stage in any lighting condition. Other outputs including the DI Output, Tuner Out, and Effects Send are not affected by the Master Volume control.

Active shelving EQ control with 22 dB boost @ 40 Hz. 

Active bandpass EQ control with 17 dB boost @ 550 Hz

Active shelving EQ control with 22 dB boost @ 3 kHz

Vintage Tone Switch
Engages analog tube emulation for the ultimate classic sound. Proprietary Vintage Circuit designed by Epifani to give you that full, warm 60's sound without breakable tubes or heavy transformers. 

Mutes the amplifier. Red light is on when engaged. The Mute is automatically engaged when you turn on the amplifier so you can set your Gain level before sending sound through to the speakers.

Rear Panel

Power On/Off
Turns your amplifier on and off. There is a 2-second delay as the amplifier performs a self-diagnostic. The Mute switch (see above) is automatically engaged when the amp is turned on.

1o Amp, 250 Volt Fuse
Protects your Piccolo from power surges that can damage the amplifier. User changeable via the fuse compartment.

Universal AC Power Port
Use the included cable to connect your Piccolo to a standard power source.

Voltage Selector (Piccolo 555 only)
User switchable to 115 volts or 230 volts for international travel. Warning: Setting the wrong voltage will damage your Piccolo. Ensure you have the correct setting before you switch on the amplifier.

Neutrik Speakon / 1/4-inch Combo Speaker Output
Connect either a Speakon twist-lock speaker cable or 1/4-inch speaker cable. For the best results use a Speakon-to-Speakon cable. If using a Speakon to 1/4-inch cable, turn the amplifier off before connecting. Do not exceed the minimum 4 ohm impedance.

Tuner Out
Connect your electronic tuner via a standard 1/4-inch instrument cable. Piccolo sends a signal to your tuner even when you engage the Mute switch.

Use a TRS 1/4-inch to connect the optional foot pedal. Use the foot pedal to engage/disengage the Mid-Cut feature and Mute.

Effects Loop Send and Return
Use a standard 1/4-inch cable to connect the input of your effects to the Send jack, and the output of your effects to the Return jack.

Effects Mix
Mix between a dry (unaffected) signal and a wet (effected) signal when external effects are connected to the Effects Loop. When you're using an EQ or Compressor, turn the Mix all the way to the right to send 100% of your signal through the effects processor. For Reverb, Delay, Chorus and other effects, start with the Mix turned all way to the left and gradually turn it clockwise to achieve the desired blend of wet and dry signal. 

Pre/Post EQ Switch
When the switch is engaged the signal coming through the DI Output will be shaped by the active EQ (see above). When the switch is in the up position, no EQ will be sent through the DI Output. 

Ground Lift
Disconnects the chassis ground from the DI Output to reduce 60-cycle hum.

DI Level
Adjusts the the output level of the DI Output. 

DI Output
A balanced, low impedance output. Connect a standard XLR microphone cable to send a signal to a mixing console or recording device.
