A long time ago in this very same galaxy, i did a pedal called the Glorious Basstar: https://www.freestompboxes.org/viewtopic ... 13&t=27124
It's a very very very cool multiband bass overdrive, but it's 8 knobs is kind of a no go for a lot of people.

So I went back to the drawing board and made a 4 knobs version called the Small Basstar. It has less possibilities, but still plenty. And it sound as big as it's bigger sister.
You can find a longer description on my website: http://zorgeffects.com/index.php/en/pro ... tar-detail

It looks like that:

So there is a kit version, and here's everything you'd like to know about it:

Hi,
Currently building the DIY Small Basstar, I have a question about C3 which has 33uF on pcb and 100uF in BOM.
What is the right value ?
Thanks.

Welcome to the forum!

C3 is part of a lowpass filter with D1 and reservoir for the charge pump, the value isn't critical. A higher value is more conservative and will offer a bit better filtering (100 uF vs 33 uF.)
