Hi guys
I was playing yesterday with my uproar and something strange happen
With the mid boost engage it starts, sometimes, to break,noise, the distortion...
I used the values suggest by Brian.
It only happens with the switch on and on full gain
Any tips?
Any one?
...
Come on guys....
is it the presence mod or the super-duper mid range booster mod?
Is the super-duper mid range booster mod
I made the presence mod but didn't make much difference...
When I flip the switch position I hear a squil noise and with the mod on I hear sometimes the same noise...
Cap values?
Could be just too much gain causing some oscillation. It might get more prominent with the mid range boost on. Try cutting R5 down to 470k - 680k and see if that stops it.
dunno man, it could be lots of things. use an audio probe and try to find what gain stage the squealing starts. being a high gain circuit, you need use either a battery or a high-quality power supply as it will be very prone to noise with an unreliable power supply.
Ok I will try swap r5 and see what happens
Thx guys
Changed the R5 to 470k and played for bit and can't hear the oscillation...
Hope it is solved
Love this animal
