Hi to all, not only guitar players
Here’s projecet of diplomatic copy of distortion+ by Dunlop. So:
opAmp -741 – I didin’t test any others “difference is provably at autosuggestion level”
diodes – germianic from TVs
casing – brass (!) pokey with red army logo
footswitch – via springs connected with cap of metal button – good shield for button.
Pcb – despite I found a lot of diagrams, I’ve designed my own ( I don’t trust thermo transfer yet)
Scoops – from TVs that I mentioned before.
I know that pictures have low quality – don’t have camera. Real colour is much nicier, you can almost see that on picture where box just has been painted.
Sound:
Pretty good; as for my ear almost like original. Sorry for no samples.
Also sory for cables – they should be buckle but I don’t care, it’s not a problem until sound is ok.
You must remember that it is not “bass boost” but just switch 47n from drive branch to 220n. At low register you will hear change, at top , you wan’t.
