  2. If Anders said 33 it's 33. I'll find the other 30. I'm on it Anders!

  3. I haven't tried this out yet but shouldn't the Input be on C1 not A1?

  4. Verified! Super loud but sounds great. Any idea what the difference between this and the tb-83 extra is? I am guessing it's something along the lines of replacing the 47k with a 50k pot or something? Or maybe there is a better way to add a volume control? Thanks!

  5. I have BC549B and C. Does it matter? I guess it depends on how loud I want it to be?

    1. You can definitely swap transistors in n out and they will work pretty similar, but you will find certain circuits work better for certain transistors. Just mind the pinout, and make sure they're not PNP

  6. Built this one and it is a pretty great treble booster. Lots of volume and I love that its a no knob layout! Has a slight bit of unwanted noise but I am also using a tele single coil.

  7. Built this with a BC549c and added a Volume knob. Sounds great. Thanks Fuzzhead

  9. What volume pot value should be chosen if added, and how the terminals should be wired to the pot ? Thanks!

    1. I suppose you would eliminate the 47k, wire a 50k pot lug 3 to where the output is labeled and then your lug 2 would be effect out and lug 1 would be tied to ground.
