Layout Verification: Bass Boost & Enhancer by STM

[O]

Could someone please look over this and let me know if it looks ok? The pot wiring is a little goofy, but it "flows" better the way the layout is laid out. The green line under the TL072 is a jumper. Here is the schematic:



and here is the layout (unverified)



Thanks in advance!

R6 1M should be to Vref not ground , looking good though

What does it do?? As what is enhancing??

Bass boost and top end "sheen" I think in the 7 - 10k range, its nice BTW

Thanks!

Thanks for catching that, MartyMart. Ok, here's the latest version with MM's catch. I'm pretty confident this is the final version. I'm about to etch the board and we'll know if it's verified or not in a few hours.

Sunday bump...

I can't see the schem...

Looks OK to me. The only suggestion - an electrolytic cap for the 1/2Vcc bypass. I beleive its C6.

Weird, I can see it...

Anyway, here it is. New host...

Cool! BTW STM: Are you the same stm from plexilandia  ??
Sorry in case you aren't. What software did you use for the schem and pcb layout?? They both look very cool.

Greetings!

Here is my PCB for BB&E in realsize pdf. Tested and working.

Wow, looks good!

[gigimarga]

can you post some soundclips with it?

Man, it took me almost a year to read this post!

Regarding your question, yes, that's me.  I use Microcap 7 to run simulations and draw schems.

Cheers.

Here a compilation of BB&E wich includes: sound samples (bass and guitar), PCB, schem, part list, info, references, credits, notes, etc.

Excellent job, Mauro!

Since links got broken, here I upload my BB&E compilation of Schems, PCBs and Audio Samples (ogg vorbis) again.

PD: If anyone knows a good file hosting server, let me know.

Guys,
Use the BBE Enhancer Plus V2.3 by STM with time alignment, it has Lo contour pot and Hi process pot for more great control. It's a BBE Sonic Maximizer Workalike.

Good luck and thanks STM,

I know it's a simple circuit, but did anyone design a PCB for it already?
