SCR-DI Bass DI with Scrambler Overdrive
The Ampeg SCR-DI Bass DI with Scrambler™ Overdrive is a true Ampeg preamp, delivering a wide range of Ampeg tone perfect for the stage. The classic Ampeg EQ offers additional tonal control including Ultra-Hi and Ultra-Lo tone shaping. Plus, you can dial in tube-like grind with the all-new Bass Scrambler overdrive. The SCR-DI has all the connections to get Ampeg tone out of any rig and send it all to front-of-house to ensure the audience hears your tone. With a built-in headphone out and aux in for practicing along with backing tracks, the SCR-DI is also a fantastic practice tool that can fit right into your gig bag
- Classic Amp tone
- DI
- Classic 3-band tone stack

Specs
Knobs
- Volume
- Use this to control the overall output level. It affects the preamp level to the balanced XLR Out, unbalanced 1/4" Line Out, and Phones outputs. Use it wisely and turn it down when making connections, putting on headphones, or trying something new. It does not affect the signal fed to the Aux Input
- Bass
- Use this to adjust the low frequency level of the SCR-DI. This provides up to 14 dB of boost, or 14 dB of cut, at 40 Hz. The low frequency output is flat at the center position
- Mid
- Use this to adjust the midrange frequency level of the SCR-DI. 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.
- Treble
- Use this to adjust the high frequency level of the SCR-DI. This provides up to 16 dB of boost, or 15 dB of cut, at 4 kHz. The high frequency output is flat at the center position
- AUX Level
- Use this to control the output level of the signal fed to the Aux Input. Use it wisely and turn it down when making connections, putting on headphones, or trying something new.
- Drive
- Use this to adjust the amount of Bass Scrambler overdrive effect. Rotate the control clockwise for a more overdriven sound, or counter-clockwise for a less overdriven sound
- Blend
- Use this to blend the Bass Scrambler affected signal with the clean, unaffected signal
Outputs
- Input
- The signal output from an instrument (active or passive) may be connected to this 1/4" Input by means of a shielded instrument cable
- Thru
- This is where you connect instrument-level, parallel effects devices (such as an FX device chain, processors, or tuner). This output is unaffected by the SCR-DI’s circuitry
- Aux In
- The audio output from line level sources, such as a mobile device, MP3, or CD player, can connect to either of these inputs. The incoming audio is mixed with the preamp signals and appears in the Headphone Out only
Post: Gain, AGS, EQ and Master settings will be sent to the D.I. XLR
output jack
- XLR Out
- Balanced XLR Line out
- Line Out
- Balanced 1/4" Line out jack
Typically, these outputs connect to the balanced input of 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 these signals are af- fected by the Volume control only when EQ is active
- Phones
- Use this 1/8"TRSstereo output to connect your headphones. The output here is a mix of the instrument signals reaching the SCR-DI, and any incoming audio from the Aux Input jacks
Ground Lift
- Ground Lift
- If there is a hum when using the D.I, there may be a ground
loop. In many cases, pushing in the Ground/Lift button can fix this problem
Switches
- Ultra Lo
- This switch, when engaged, enhances the amount of low- end output by 1 dB at 40 Hz, and 10 dB cut at 500 Hz
- Ultra Hi
- Thisswitch,whenengaged, enhances the amount of high frequency output by 5 dB at 8 kHz
- Scrambler
- Engage this switch to activate the Bass Scrambler overdrive circuit. This allows for varying amounts of tube-like grind and distortion
- EQ switch
- Engage this switch to activate or bypass the EQ section.
NOTE: The EQ and Bass Scrambler overdrive circuits are able to be activated and bypassed independently via their footswitches

Power
- Battery
- The SCR-DI may be powered by 9V battery instead of using a power supply. As seen in the illus- tration above, a 9V battery fits nicely inside a compartment of the circuit board next to the edge of the pedal
- External DC Power
- External: 9–12V DC @ 100mA
