Hey so I have built the gate only using a 1k for r27 the status led and a tl071 and 2n5088/87 in place of stock transistors q1 is getting to hot to touch I am getting no effected signal but I am getting signal in bypass mode! I do not know what the voltages should be but will measure them and post. Also there are absolutely no solder joints I have checks dozens of times. Does anyone have any idea?
The wild man with a loaded gun and no plan. I'm not held back by rules, just don't know which ones to follow

You did check the pin out of the 5088/87 right?

They should be facing the opposite way than the BC550s are depicted on the layout.
I just designed a new fuzz circuit! It almost sounds a little different than the last fifty fuzz circuits I designed! ;)

It's going to be either R22 or R17.  I don't know which.

Hello I came across this project on madbean's website
Someone compared this loudspeaker with ISP Decimator
Or is there nothing better ISP?
