So...i use my boost a fair bit but i am incrasingly not liking that its a fuzz after 1 o cloock
I increased the Emitter resister from 390 to 1k and all that has done is lowered the amount of boost, so im hesitent to replace and then lower the 10k instead...
Is this a losing battle, or can i make this a clean boost with all the volume and little fuzz?
A circuit can only amplify a certain amount before it starts to clip. Your hard limit is the supply voltage. If your input signal is already large, then you can easily overdrive a boost circuit early on. So let's say that your guitar creates a 1V signal, and you amplify it 10 times -- you need 10V, but your pedal is only running on 9V. The excess is clipped. If you try to amplify it 30 times, you'll clip it a low. If you have high-output pickups that create a signal of 2V, you can only amplify it a little more than 4 times before you start to clip the signal. The only way to avoid distortion is to reduce the amount of gain (input signal size), reduce the amount of amplification (turn the boost pot down), or increase the supply voltage (as long as your components can handle it).
This is similarly why bigger amps are louder before distorting.
