The other thing to consider is the use of a buffer or booster in front of the amp that might give you a better gain level to play with. Before swapping pots out, try the diode substitution, then see what you have to work with.

The only thing I would caution about here is trying all the mods all at once.

Or even putting two red LEDs in series on one side and three 1N4001s on the other might be something to try. Adding an extra identical red LED in series on either side of your clipper will allow more gain before clipping. The diode ladder is interesting but you may want to consider the amount of current available to push through a bunch of diodes on that scale. Best way to convert a linear pot to audio or reverse audio taper is to buy another pot.Īs far as the clipping diodes, I don't have one of these amps to try out but the suggestions put forth elsewhere seem to point towards simply adding other diodes in series to increase the clipping threshold thus hopefully reducing premature fizz.
As long as your pots are both 50K for bass and volume, the taper does not matter except that it might be more useful to meet your particular needs.
Quick reaction: The thread you referenced in ssguitar seems to address your questions pretty nicely as far as the problems with gains and levels. I would be grateful to any help you are kind enough to provide. My question is how can I figure out how many stages I need and what resistor values should I use ?Ĥ)Is there any other way of improving this amp that you can think of ? So that I have better transition from crunch to overdrive and finnaly distortion. Pot labeles on my amp are: B104 for gain, ALPHA B50Kohm for treble, A50Kohm for bass, ALPHA B50Kohm for volume.ġ) my first questions is : can I swap bass pot with volume pot ? won't there be any problems with bass (other than it being linear)?Ģ)Should I use anti log pot for gain ? if so, how can I change a linear pot to anti log ?ģ)also for the diode clipping stage I thought of implanting a limiter (diode ladder) like this :
since its old and OP's last visit was long ago I've decided to post a new topic.Īs mentions in the other topic the main changes I should do is :Ī) changing linear volume pot to a log pot. This topic answered a lot of my questions.

I have a pathfinder 10, here is the schematic :Ī- volume is not very usable, and seems to be linearī- when I switch to overdrive channel, gain suddenly goes up and altering the gain knob should have transition between overdrive to distortion, but goes to full on distortion even at 9 o’clock. I know that this forum is for stompboxes but since I didn't get any replies in ssguitar forum I thought you guys can maybe help me.
