Gain Stage HELP

[matthew1234]

Is it possible to properly feed a transistor gain stage into a CD4049 chip gain stage? for example adding transistor gain stage into The Great Destroyer circuit.

Thank you

What do you want to accomplish with the additional gain stage?

[matthew1234]

I want More distortion/fuzz

Do you want the pedal to oscillate the way it normally does?

The problem that I see is that this pedal will most likely not oscillate the same way or may not oscillate at all with an additional gain stage at the front

[matthew1234]

That's okay, I don't need it to oscillate :)

An easy cheap way to do this would be to connect an LPB-1 circuit to the input of the great destroyer.

[matthew1234]

That's a great idea actually! Thank you so much!!!

Is this how it should look? I changed the gain stage a bit.

Thank you!

[Travis]

Sorry, no that isn’t correct

Here’s the schematic to the LPB

[matthew1234]

I based it on this similar schematic instead

Neither the component values or connections in your schematic match the LPB-1

I will probably have time this weekend to draw up a layout including the LPB>Great Destroyer this weekend if you don’t mind waiting for that

[matthew1234]

Thank you very much. I appreciate that

I corrected the schematic.

[Travis]

Could you please link the boost schematic that you used?

It is in this PDF article by Premier Guitar on building a DIY distortion pedal [ Page 19 ].

I Changed the value of the Transistor to ground resistor to modify the gain.

The schematics I used for TGD are

Hey,

If possible, could you please convert the schematic to veroboard layout?
Thank you very much!
Matt

[Travis]

For sure buddy I should be able to do it tomorrow or Sunday

[matthew1234]

Thank you so much. I really appreciate it

[matthew1234]

Hey, did you get a chance to look at it on the weekend?

[Travis]

I basically copied Mark's layout, grounded unused inputs, and added the gain stage at the input. I used the first schemaic in your link which is just the gain stage, it doesn't have a gainvolume control for that stage. We could add a gain control there if you need it
