Presence control in Dr Boogey.

[ubaid88]

I have recently build a Dr Boogey.
Using this schematic.

It works very well except that i have noticed that presence pot is not interactive??

how should i mod this? please give any suggestions for replacement of component(cap and resistor)presence control to make better.

Thanks you.

But way here is my dr boogey.

what do you mean interactive?
if you mean that it does too little or nothing, try changing the pot to 20k and the cap to 33n.. i use that...

[ubaid88]

i mean it does nothing. I dont see difference. I will try your mod. Should 22k resistor as it is or change it to 2.2k

[dschwartz]

i dont use the resistor,try putting a jumper instead. iF it´s too extreme, put something between 1k-5k

why do you need transformer? it's very close to input jack, you may have noise issues

My dr boogey is different. I used cascodes instead of single fets, they make gain stage electrically and physically isolated. Iam giving 24v supply so i need regulated supply. I will explain about this later.

thanks you its working
