Page 5: Soldering Tips
SOLDERING TIPS It is important to make a good solder joint at each connection point. A cold solder joint is a connection that may look connected but is actually disconnected or intermittently connected. (A cold solder joint can keep your project from working.) Follow these tips to make a good solder joint. -

SECTION 1 – Mount ¼” Jacks and Terminal Strip Components Please refer to DRAWING 1 and DRAWING 2. Input Jack Orient box with single centered 5/16" hole on top and ½” hole nearest you. RING LUG GROUND LUG Mount input jack in 3/8" hole on left side of box with hardware provided. Washer goes under nut on outside of box. -
Page 7: Section 2 - Wiring The Jack, Footswitch And Power Supply
1) Mount two 1M resistors to the lower set of holes of the terminals listed below, but do not solder. Terminals #4 & 6: 1M resistor Terminals #6 & 8: 1M resistor 2) Mount a 2 ¼” piece of wire to the lower holes of terminals #2 and #6. -
Page 8: Section 3 - Finishing Up
Please refer to DRAWING 4. 1) Connect a 2 3/4” piece of wire to terminals #5 and #12. 2) Connect a 1 ½” piece of wire to footswitch lugs 3 and 6. (Bend this wire down so it rests flat against the back of the footswitch. This will keep the battery insulated from the footswitch terminals and prevent a possible short across the battery casing). -
