To wire our products, first locate the four screw terminal pairs on the back side of the product (the side with the wiring). Each of the four screw terminal pairs has two screws, a bottom screw (closest to the product bottom edge) and a top screw (closest to the product toggle switch). Each used terminal pair has either red wires or white wires connected to their upper screws, with red indicating a positive terminal pair, and white a negative terminal pair. You will be connecting your load(s) using the bottom screws (only) of the used terminal pairs. Please don’t loosen any of the other screws on the terminal strip or switch, as these have been tightened before shipping using a torque drive to ensure they never loosen inadvertently in use.
ToneDoctor recommends 18 gauge solid core copper wire for all wiring involving the transfer of power between your amp and load(s). Compared to the same gauge of stranded wire, solid core wire handles more current, with less resistive loss, and also less parasitic capacitance and inductance, resulting in more transparent power transfer. This is why all wire used in your ToneDoctor product is solid core 18 gauge copper. It’s also the reason why the wire used in the wonderfully sounding Two Rock Crystal Clear speaker cables is solid core 18 gauge copper wire. You’ll find 18 gauge solid core copper wire available at Home Depot, Lowe's and other hardware stores in two-wire (red & white), twisted pair rolls, where it’s referred to as “bell wire”, as it’s commonly used to transfer AC power to doorbells and chimes in home wiring applications. It’s available by the foot, at less than twenty cents per foot of the two-wire, twisted pair, offering a great “tonal” return on investment.
Incidentally, this is great wire from which to make speaker cables for connecting your amps to our products. Radio Shack sells ¼” mono male plugs for a few dollars each, in either straight or right angle versions (we recommend the right angle version to ensure that the plugs don’t protrude out of the back of your speaker cabinet or combo amp). If you are handy with a soldering iron, you can make your own cables for less than five dollars each, and they’ll sound far better than conventional cables, and comparable to anything else on the market today.
You’ll have to unmount the ComboMojo products in order to wire them, as you’ll need ready access to the product screw terminals. After laying your combo amp face down on the floor or a table, simply loosen the large knurled metal knob to unmount the product, and then lay the product face (label side) down on your combo amp back panel, with the bottom edge of the product along the top edge of the back panel. This arrangement preserves the right-to-left orientation of the product, facilitating correct wiring.
Deuce
All four screw terminal pairs are used in wiring these products, corresponding to the configuration requirement of two loads.
Looking at front of the cab or combo amp, wire the right/top load to the two right-most screw terminal pairs, and wire the left/bottom load to the two left-most screw terminal pairs, connecting the positive load terminal to the bottom screw of the positive screw terminal pair, and the negative load terminal to the bottom screw of the negative screw terminal pair. Tighten all four bottom screws securely to ensure they never loosen inadvertently. You can now remount your product to the combo amp back panel by “rotating” it around the top edge of the bottom back panel of your combo amp and then tightening the large knurled metal knob.
Solo
Only two of the four screw terminal pairs are utilized in this product, corresponding to the configuration requirement of a single load.
Wire the load to the two used screw terminal pairs, connecting the positive load terminal to the bottom screw of the positive screw terminal pair, and the negative load terminal to the bottom screw of the negative screw terminal pair. Tighten the two bottom screws securely to ensure they never loosen inadvertently.
