3.1 Cnap-smachd

  • Measgachadh: Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is controlled by the Drive knob, allowing for fine-tuning of the blend ratio.
  • Ìre: A’ suidheachadh meud toraidh iomlan a’ pheadail.
  • Drive: Controls the amount of gain in the overdriven signal.
  • Ìosal: Adjusts the level of the low frequencies.
  • Lo Mids: Adjusts the level of the low-mid frequencies. The center frequency can be switched between 500 Hz and 1 kHz.
  • Hi Meadhanach: Adjusts the level of the high-mid frequencies. The center frequency can be switched between 1.5 kHz and 3 kHz.
  • Treble: Adjusts the level of the high frequencies.

3.2 suidse

  • Tionndadh ionnsaigh: Modifies the treble content of the overdriven signal. Options are Boost, Flat, and Cut.
  • Gluasad Grunt: Modifies the low-end content of the overdriven signal. Options are Thin, Raw, and Fat.
  • Lo Mids Switch: Selects the center frequency for the Lo Mids knob (500 Hz or 1 kHz).
  • Hi Mids Switch: Selects the center frequency for the Hi Mids knob (1.5 kHz or 3 kHz).
  • Tionndadh lioft talmhainn: Disconnects the ground from the XLR output to help eliminate hum or ground loops when connected to external equipment.

3.3 Ceanglaichean

  • Input (1/4" Jack): Connect your bass guitar or other instrument here.
  • Output (1/4" Jack): Connect to your bass ampinneal-losgaidh no peadalan buaidhean eile.
  • Direct Output (XLR): Provides a balanced output for connecting directly to a PA system, mixing console, or audio interface.
  • Parallel Output (1/4" Jack): Outputs the unaffected input signal, useful for parallel processing or sending a clean signal to another device.
  • Cuir a-steach 9VDC: Connect a regulated 9V DC power supply (center negative, minimum 30mA).

4. Suidhich

  1. Ensure the pedal is powered off before making any connections.
  2. Ceangail do ghiotàr beus ris an Cuir a-steach seacaid air taobh deas a’ pheadail.
  3. Ceangail an Toradh jack on the left side to your bass ampcuir a-steach an neach-saoraidh.
  4. If using the balanced output, connect the Direct Output (XLR) to a PA system, mixing console, or audio interface.
  5. If you need an unaffected signal, connect the Toradh co-shìnte gu inneal eile.
  6. Connect a regulated 9V DC (center negative) power supply to the Input 9VDC. The pedal requires a minimum of 30mA. Note: A power supply is not included with the pedal.
  7. Once all connections are secure, you can power on the pedal.

5. Stiùireadh Obrachaidh

5.1 Gnìomh Bunaiteach

To activate the pedal, press the footswitch. The LED indicator will illuminate. To bypass the effect, press the footswitch again.

  • Start with all EQ knobs (Low, Lo Mids, Hi Mids, Treble) at the 12 o'clock position for a flat response.
  • Atharraich an Dràibheadh knob to achieve your desired level of overdrive. Higher settings will produce more distortion.
  • Cleachd an Measgaich knob to mix the clean signal with the overdriven signal. This allows you to retain clarity and low-end presence while adding grit.
  • Dèan deuchainn leis an Thoir ionnsaigh agus Grùnt switches to fine-tune the treble and bass characteristics of the overdriven tone.
  • Utilize the 4-band EQ to sculpt your overall tone. The Lo Mids agus Hi Meadhanach switches allow you to select different frequency centers for precise control.
  • Atharraich an Ìre knob to match the output volume with your bypassed signal or to boost your signal for solos.

6. Cumail suas

  • Cùm am peidal glan le bhith ga sguabadh le clò bog, tioram. Seachain innealan-glanaidh no fuasglaidhean sgrìobach a chleachdadh.
  • Protect the pedal from extreme temperatures, moisture, and direct sunlight.
  • Dèan cinnteach gu bheil na càbaill uile ann an deagh staid agus ceangailte gu ceart gus casg a chur air call no milleadh comharran.
  • Always use a regulated 9V DC center-negative power supply to avoid damage to the unit.
