modding the usa big muff to vintage spects?

[msurdin]

Does anyone have a layout of what parts to replace in the new usa big muff to make it close to the 75's spects?

This would be a great help!

Thanks guys

If you're OK desoldering a few things, after taking out the circuit board, the you'll probably think it's pretty EZ. Mainly just tweaking the tone stack.

here is a great link to help you, and help you decide which muff to copy:
