Hello everyone!
I was recommended to this forum from a friend because he thought you guys might be able to help me.
I am trying my hand in building my own DIY guitar stomp boxes and while some of these answers may have to come from a niche crowd, I feel that FET boosters are something that most of you may be familiar with.
I have the circuit built and it amplifies (boy, does it amplify!) but what is happening is when the pot is anywhere but 100% clockwise, there is no change in volume. When it moves that tiny amount from 99% to 100% clockwise, it turns on the transistor full blast and not only SUPER amplifies the guitar's signal but also, distorts the signal. Now, I don't mind if it distorts at full volume but I would like to have a gain knob that actually works the way it should.
The diagram I am attempting to follow is
Now, I have all the parts listed to the T except for the 62k resistor where I used a 56k and two 6k resistors. At this point, I'd like to mention that I am quite new to actually building circuits; however, I have a pretty decent grasp of the basics. That being said, I am sure to make a few newbie mistakes.
I will attach two more images in an attempt to help with someone's diagnoses.
The first is my interpretation of the diagram as I follow the signal path through the breadboard:
I have color-coded the transistor pins to show how I interpreted the info sheet. I know this is normally one of the biggest issues when working with transistors so, I figured I'd describe it as best I could.
The second image may be of no use but it's the actual breadboard I have currently. Nearly impossible to see connections but I figure it may help?
Well, that's all from me for now. I appreciate any help or insight you can give me. I am even unopposed to the idea of tearing it all down. Again, I'll say I am very new to this but get giddy when I have new ideas for pedals and audio augmentation! Thank you for your time!
