We can't say much about how to join the club, but modding your EHX Triangle Big Muff may get two or three steps closer! After the Mod you will have a few more options to lock in your perfect tone!
Toggle up is Stock Triangle Muff distortion
Toggle middle provides a more open/powerful distortion
Toggle down will give you more saturation and full raging fuzz
The Gate knob lets you dial in the exact right amount of spitty gated fuzz
