Hey guys. I have an updizzle on the Legend of Fizzle. Wait... What?


Anyhoo...


I took it to a local guy, and he desoldered the hot side of the volume control (the left side when looking at the guts) and inserted a 2.7 meg resistor between the hot wire and the volume control. Unity gain is now at NOON! Glory!

That sounds about right. I put in a 1 MOhm resistor and it wasn't enough. I'll get around to fixing that eventually.

I also added a resistor to my Brassmaster clone and while it does help, it causes impedance issues with the output going to other effects. So it looks like it will need a volume pot, possibly before the final gain stage.

Here is a link to a drawing of the mod that the guy sent me. Is there a place on TB this stuff is archived?

The markings on the bottom of the pot are using batch numbers. The value is on the other side. It's a B100K pot.

I was wondering what the triangle in the schematic above is.

Is is just an IC? If so, why is it shaped like a triangle?

That's the schematic symbol for an IC.

It's an IC. The component is called an op-amp, short for operational amplifier.

It's the schematic symbol for an amplifier, which is usually in the form of an op amp which is a type of integrated circuit (IC).

If so, why is it shaped like a triangle?

It's just the long-accepted way of denoting an amplifier in a schematic.
