Blackstar Fly 3 schematic request

Postby bancika » 10 Apr 2017, 10:01

Hi,

anyone has schematic of this little amp? I own it and am just curious to see what they did.
It's all SMD, so it's a bit of a pain to reverse engineer. Would maybe consider modding the tone stack if it's possible to do without too much SMD work, but it's unlikely.

Tnx,
Bancika

Didn't find schematic but I was able to make this cool little amp much cooler. It's good sounding, although a bit dark and for metal it lacks gain. It's possible to fix using a booster, but it kind of defeats the purpose of a super-portable mini amp.
So I built a small JFET booster, found a trace to cut so I can inject it in the circuit right after the input jack and added a DPDT switch to bypass it. It turned it into a 4 channel amp. Booster adds at least 6-9dB and pushes the amp into heavy distortion but also helps bring out the highs significantly. Loving this little amp even more now :)
