BUILD NOTES

Variants

The Big Muff is famous for having dozens of variations that sound very different from each other, and

Kit Rae's fantastic

list for the Halo is based on the

any of the versions.

The

Big Muff Versions spreadsheet

can easily retrieve a list of values for a particular variant and build the Halo to those specifications. Note

that for all versions, the transistors, diodes and potentiometers are the same, so only the resistor and

capacitor values are provided.

Mids Switch

The midrange switch is a DPDT on-on-on. For this type of switch, depending on the manufacturer, there

are two different types of configurations for the center position:

Fortunately, the way the switch is used in this circuit, it doesn't matter which type of switch you have.

The EQ response will still be flat in the middle. Just make sure not to use an on-off-on switch.

If you aren't able to find a DPDT on-on-on switch, you can also just use a standard DPDT on-on switch.

You will still have the mid hump and mid scoop modes, but you will not have the flat mode.

Note: If you are building a variant other than the default, you may need to adjust CX1 and CX2.

• CX1 should always be the value specified for C11

• CX2 should always be the value specified for C10

Hardwiring the midrange switch

If you'd like to leave off the midrange switch and hardwire it in the stock mid-scoop position, install wire

jumpers as follows:
