Bass Booster Hogs FootThis bass booster is the Hog's Foot or Mole. It is a Linear Power Booster tuned for bass, it will give the lows you need.
DESIGNATORS AND COMPONENTS Step 2 of 4
The following table shows several guitar effects that you can build with the DH.A8 PCB. Note that some components are a jumper or don´t need to be placed.
GENERAL DESCRIPTION OF COMPONENTS
The resistors are ¼ Watt metal type. You can either use a multimeter or the color bands to obtain their values. Resistors don’t have polarity; you can assemble them in any direction.
In some cases the component value is "jumper". You can use a small wire or component leg to create it. They are mounted on the component place (diode, resistor, capacitor... )
Electrolytic capacitors have the value printed on them. The polarity is also is marked for the negative lead, additionally the longer leg is the positive and shorter the negative. Assemble the electrolytic capacitor according with the positive polarity (+) marked in the PCB, that is, the longer leg of the capacitor is passed through the pad marked with +.
The polyester capacitors have three numbers, read as picofarads (pF), the first two are the 1st and 2nd digits and the third is the multiplier code. This type of capacitors doesn’t have polarity; you can assemble them in any direction.
Diodes have their type number marked on them. This two terminals component has polarity; a ring near the side indicates the cathode. This ring is marked as a line to indicate the correct polarity in the PCB.
Led diodes have polarity, the cathode is indicated as a flat surface on the side of the diode and also it is the shorter led. On the PCB, the cathode is marked as a flat side and anode as a round side.
Transistors are three terminals components and their model and name are printed on them. To indicate the correct assembling position one side of the transistor is flat and the other one is round, in the same way, the PCB is marked with round and flat side.
Potentiometers can be mounted directly on the PCB. For a correct orientation, the potentiometer shaft is marked on the PCB.
