Ampeg SCP-OCT Owner's Manual

The AMPEG Scrambler Series SUB-BLASTER octave divider is easy to use, accurate and quick in its tracking, and very musical. This unique octave divider is an analog circuit upgraded from the one used in the popular SVT-5 Pro ampli- fier head. The SUB-BLASTER features a rugged die-cast metal housing for rock-solid durability. This design is based on the original Ampeg Scrambler overdrive pedal from 1969 and is very road worthy.

tion will result in the ability to use each of the sounds that the unit can produce. Don’t be afraid to experiment with all of the controls – a little time spent with the SUB- BLASTER will enable you to use the unit to its fullest capacity. The “Direct” control adjusts the amount of unaffected signal added to the output. The gain structure of the SUB- BLASTER is designed so that maximum headroom is pre- served throughout the direct signal path. The “Octave” control adjusts the amount of “octave” effect added to the output. Tracking accuracy has been greatly improved over other octave pedal designs. On a five string bass, better results will be obtained by fretting the note on the B (fifth) string, fifth fret, rather than playing it as an open E on the fourth string. The tracking will be maximized in the middle of the neck by using the neck or rhythm pickup. Tracking will still function well in all ranges with the bridge pickup, but for optimum results the neck pickup is recommended. Ampeg Pedal SUB-BLASTER SUB-BLASTER

clicks or pops at a level equal to the SUB-BLASTER out- put level. Thus, you do not have to reset your volume control on the amplifier each time you switch the effect on and off. The SUB-BLASTER uses a “true bypass” switching system so that when the effect is turned off, the signal is literally connected by wires from input to output. The input and output jacks (marked “guitar” and “ampli- fier”) also provide battery on-off switching. When not in use – unplug the input (“guitar”) jack to conserve battery power. When using multiple effects, place the SUB-BLASTER early in the signal chain – before distortion, envelope, chorus effects. This is because the SUB-BLASTER likes to see a pure sine wave signal – the waveform modifications produced by the aforementioned effects may have a dis- ruptive effect on the operation of the SUB-BLASTER. Always place the SUB-BLASTER as close to the signal source as possible. Ampeg Pedal SUB-BLASTER SUB-BLASTER

DC adapter (not included) or a 9V battery. When using a 9V adapter, insert the barrel connector of the adapter into the “9V DC” jack (between the “guitar” and “amplifier” jacks of the SUB-BLASTER), then plug it into an appropriate source of AC voltage. Unplug the power supply and disconnect it from the unit when not in use. The SUB-BLASTER has a min- imal current draw – an 9V alkaline battery should last a long time. When the time does come for a fresh battery, remove the four screws from the bottom plate (one at each corner). The battery is held in place by a metal clip. Remove the old battery from the clip and disconnect the battery wires from the top of the battery. Reverse the process to install the new battery.

The Ampeg SUB-BLASTER is an effect designed for huge, responsive sub-bass tones to augment your tonal arsenal. Please read all of these instructions and use them as you explore your new Ampeg SUB-BLASTER. Thank you, and enjoy!
