Box of RockThe Box of Rock pedal emulates the JTM45 tone, a remarkable classic distortion sound. This pedal has very high headroom and you will be able to control the distortion tone by using your guitar volume knob.
PCB ASSEMBLY Step 3 of 4
You should use a solder pencil of 15-30W and solder of 1 mm of diameter 60/40 (60% tin, 40% lead). The solder will release fumes that are harmful to your eyes and lungs, work always in a well-ventilated environment and avoid breathing the smoke created.
Warm up the iron and clean it with a humid sponge before soldering. Place the component and firmly hold the PCB on the table or holder. Heat the pad and the lead for one second by touching them at the same time. Then, feed around 1-3 mm of solder and make sure it flows properly. If the solder has not been applied correctly you can create a bad connection (cold solder joint). A good connection should cover the path and lead without touching any other pad. Finally, cut the lead with a cutter and inspect the joint by visual or by using a multimeter.
Assemble the components on the side of the silkscreen according with the designators and with their correct polarity. It is recommended to solder the components from small to big: resistors, diodes, capacitors, transistors, potentiometers... The PCB is designed to mount the potentiometers on the PCB: Gain and Volume on the silkscreen side, Tone on the side without silkscreen. For the IC you should use the socket. It is possible to assemble the components on both sides if required, just be careful to keep their correct polarity.
