Bass 6-Band EQ?

[ShaneAngelRiot]

Will there eventually be a bass 6-band EQ PCB or maybe in the same vein as the Muffin Fuzz where there's a separate list of parts to assemble a bass version?

The 6 band EQ is just a set of gyrator filters. You can use a gyrator calculator to figure out values for whatever frequencies and Qs you want.

As mentioned above, you just need to change a few components to change the frequency bands. I do think it would be a great idea if, since the faceplate is printed on both sides, one side has the stock frequencies labeled, and the other side had the bass eq frequencies labeled, so you could use the same faceplate for either version

So if I just change the values of the certain capacitors I'll be able to change which frequencies I want each pot to effect?

Caps and resistors. Do you know what frequencies you'd like to see on this? I think I kept notes on how I changed the frequencies on mine for guitar.

I used a calculator and got some results in a way lol

I was aiming for 55-110-250-560-1500-3500

Check the math but this might get you in the ballpark:
