DOD/Black Arts Toneworks Boneshaker

Postby jrfox92 » 05 Apr 2017, 05:48

After having a look through this thread I drew up a schem for the Boneshaker (sans resistor/capacitor values).
(see below)
I'm 95% sure this is correct.

Great start, thank you. From the descriptions, it seemed like a dod250 with a parametric 3 band eq before the gain stage and nothing more, but you say the highs come later.

Looks like I got the Freq and Level controls labeled backwards.
Here's the updated schem:

Really can't stand the inability to edit posts.

After another look through (and some peer review), I realized I didn't have the LED oriented properly and didn't connect pin 3 on the Mid Volume due to the trace being obscured by the pot's shadow in the gut shot image I worked from. Also, mid freq pin 3 was obscured, I just cracked it open and checked it with a meter, so that's fixed, too. [smilie=a_doh.gif]

Out of curiosity why did you label your IC's w/ the suffix 'P'. In the photos they're quite clearly marked 'C'.

That is just Eagle's way of differentiating between packages (DIP, QFN, QFP, TSSOP, ...), nothing to do with the actual part. The suffix from the manufacturer is usually some kind of grading: temperature ranges, accuracy, etc.

Hi, are there values for the gyratorEQ? Just curious about, what freqanhebung and Qs they used.

Thanks for the ckt trace. :applause:

There have been several comments in the forums that say the EQ is pre dist. Cause if you crank the EQ it gets dirty. Your trace shows that the EQ is not pre dist.
