Hi there, a friend want use an American Reissue Big Muff with a electric bass.
This version had all coupling caps at 1uF so there i can't change anything.
What do you recommend? the tone stack maybe?

The stock circuit is already VERY bass friendly. Have him try it without any mods first. Having said that, some bassists I know have preferred tacking a clean blend in it. Search my layout gallery for the "Buff N' Blend" circuit. The PCB is around an inch square and works great!

Personally, I think 1uF caps are too flubby for bass.
I like .1uF coupling caps in my friend's BMP I modded.

+1 clean blend.
Adjust to taste. With the clean signal you have more bass frequencies and
a tighter bass fuzz sound. Just adjust to taste.
If you don't want a clean blend then omit the first set of diodes, a la "jumbo
tone bender" bigger bass sound, slightly less fuzz/fizz. More output level as well.

Ok, I'll take off the first set of diodes,

Here are some mods, including that of the diodes. just found it.
