Blackstar Dual HT Boost box DIY ...nearly done

[mykaitch]

Ouch! That 300v is a wake-up when you grab it!
So, all working , just testing it a bit.
For a given input,say from Guitar, what would you expect the output to be?
If we assume around 10mV from the Guitar.

I have rigged a true bypass.
I notice that CRUNCH gives a higher o/p (Volts pp) than CLEAN but looking at the circuit that seems right.
In use if you flip from CRUNCH to CLEAN the LEVEL might want a tweak.
So far I am testing with sig gen but expect to piug in this week-end.

So it is on vero and about half the size of the original.
