Rattler says: 14/10/2011 at 21:01 Hey man, this looks really sweet and Im looking to build it but I cant figure out from either of the diagrams where the LED goes in respect to the PCB its probably just me being dumb but I cant see it Reply Bancika says:
8、 14/10/2011 at 23:02 its not on the pcb at all. I just connected it to +9V through a resistor. Theres no bypass so its always on. Cheers Reply Rattler says: 15/10/2011 at 11:32 OH right, cheers man Reply 6. Edson Souza Lima says: 15/09/2011 at 06:50 Is the output sound clean? or with distortion? Tks
9、 Reply Bancika says: 15/09/2011 at 09:42 Its clean. This simulates only frequency response of a marshall 412. Youd need a bit more to simulate cone distortion. Cheers Reply 7.

10、2011 at 13:26 I have seen this circuit on another site and on it, theres a clip Reply 8. Simen says: 08/06/2011 at 20:07 Hi! I want to build one of these, but I still lack some knowledge when it comes to op-amps. Most pedals out there use negative tip 9V power supplies, so I experimented in a Circui
11、t simulator with -9V, and my first thought was to just flip all polarities, what goes to Op-Amp In- moved to Op-Amp In+ etc. but that didnt work as expected. So I tried flipping the Op-Amp inputs one pair at a time, ending up at the exact same configuration as in the schematic, only difference actua
12、lly being the power supply being -9V instead of +9V (and the output signal having a negative DC offset instead of positive). Is this correct? Is there anything else I must consider? Short version Do I need to make any changes to the design/layout to use -9V instead of +9V? Reply Bancika says: 08/06/
13、2011 at 20:10 Im an op-amp noob myself, so cant help much. I just built the +9V version according to the schem. Cheers Reply 9. Tom says: 03/03/2011 at 18:52 How does this speaker simulator sound? Do you have any clips of it? Reply 10. Snowstorm says: 20/06/2010 at 15:19 Hello! Im interested in this

15、 is a schematic and layout in “Useful links” section of the article.
