Hi guys,
I recently built a coloursound jumber tonebender following this layout:

I have 2 issues there:
1° I need to almost turn all the way up the volume pot to have decent amount of sound. Any idea from where the problem could come from?
2° Also I have almost no gain. Do you think it could come from the fact i replaced all the 500pf caps by 680pf caps? And replaced all the transistors (BC184C) by 2N5088 transistors?
Thanks :)
Here is the schematic:

Numbers 1° and 2° are the same complaint. It's not the parts you used.

It might be the parts you used, if those parts are of wrong value..
e.g. 82k instead of 8k2 and/or 47k instead of 470k..
Or 1k instead of 100R, or 1k5 instead of 15k or.. or..
Hello
Point 1. Could be a number of things causing this. Photos and voltages if you can? Otherwise it's a guessing game.
Point 2. No - changing transistors and those caps will not be responsible for low levels.
Good luck
Check your transistor pinouts. If c and e are swapped you could get low gain.
If possible post voltage measurements for the transistors.
Thanks everyone!
Turns out, transistors were not the right way.
Now everything is working!
