Let's think of it like this: Imagine bouncing on a trampoline in your garden - that's like an audio signal going up and down every cycle. com/boss-ds1-analysis (another ElectroSmash circuit analysis) you'll see how the Fly circuit uses the exact same hard clipping arrangement as the Boss DS1 pedal. However, when the voltage is reversed, a Zener diode blocks current UNTIL a magic voltage is reached where lots of current starts to flow.

Industry norms are approximately 70%, so that 15% saving is reducing your energy bill and softening your environmental impact on the planet.I traced out the circuit for the power supply as best I could, although there are a couple of components I'm not sure about as I'll explain later. I haven't talked about the circuit around TR1 which drives the " POWER" LED on the Upper Deck board . There's a bunch of maths (sorry math if you are in the USA) which speaker designers use to make ports in their cabinets resonate at the frequency they want. Clipping gets built into guitar amps (like our Blackstar FLy3) because it mimics what a tube amp would do when really pushed (except with the 3W Blackstar Fly your ears are not flattened when the amp is clipping). which might seem unexpectedly high for a tiny portable 3W amp like this, until you realise that the Class-D power amp (Speaker Board) can demand some hefty current for very short periods, when it pulses the speaker current on and off.

So the speaker is a sort of hard-wired EQ in itself, and its the reason a guitar plugged straight into a desk or PC and recorded direct sounds nothing like a mic'd up speaker cab. Powering our booster directly from batteries would drain them even when the amp is not turned on, so we want to make sure to get the point in the circuit that’s downstream from the power switch.

As usual for PCBs, ground on the Main Board is mostly copper fill in between all the other traces - what's known as a Ground Plane.

If a current flows into something, it must come out again somewhere (yep there's a name for that law too - Google " Kirchoffs First Law"). FAQ2: I've plugged my guitar/pedals into both the Blackstar Fly3 and into another guitar amp, and I get hum.
