Question preamp with LM3886 poweramp

Hi!

I just recently started getting interested in designing a guitar amp... but as anyone i could use some advice... i'm also wondering about some stuff...

Here's my schematic:

Click the image to open in full size.

Here are my questions:
- since i'm running the preamp section on +/-15V i guess i can't use the polar capacitors? (the ones at the output of the clean channel and at the input of the tone control)

- should i connect the gnd from the input with the gnd from the power supply?

thank you for your help...

Didier

Hello

well, i discovered that my schematic has some minor errors in it, i will be adjusting and uploading the new schematic tommorrow if i find the time.
prototyping should be done by the end of the week... since i don't have certain parts now.

anyway, you should know this is my first project and it might as well just fail and cost me a lot of money.
on the other hand so far its already a great learning experience, so i expect to even learn more...

great to know there is some interest in my work.

i also posted all of this at arons forum ( http://www.diystompboxes.com/smfforu...?topic=39664.0 )

many usefull info can be found there too...

keep on rocking!

Dieter.
