5th Gear Overdrive v3.0
« on: March 19, 2020, 02:47:30 PM »
I've had some time recently and have made some adjustments to the 5th Gear Overdrive I designed in college (https://www.ssguitar.com/index.php?topic=11).  This is pretty fantastic now.  No more noise when adjusting gain level, awesome clean when rolled all the way down.  Using my telecaster with regular Fender single coils it has a great edge of breakup sound around 10 o'clock, coming into solid rock and roll territory around 2 o'clock, then full on screamer at full gain.  Not quite metal gain, but honestly, getting close.

Try it, you might just love it!

Thanks for posting that. Looks cool, might try it.

Which diode is the LED and which is the 4148?

Can two general purpose NPN transistors be configured as the darlington, or does the sound depend on the characteristics of that particular transistor?

It doesn't matter which diode is which as long as you have them facing opposing directions.  I haven't built it with general NPNs as a darlington, but others have on diystompboxes, and it seems that it works fine.  That said, I had another person build it and try a bunch of trannies and couldn't get the exact same sound as MPSA13 with anything else - close enough to work, but not quite the same.  Take that for what it's worth!
