Modded my cute little Blackstar Fly3

[bancika]

I wanted to beef up the tone of my Fly3, add more gain and make the preamp a bit more "present" sounding, as it's quite dark. Tried replacing the speaker and it added upper mids but also made it sound a bit boxy, so I reverted that mod. There's no schematic to be found and it's all SMD, so circuit mods are out of question at the moment. Instead I added switchable JFET booster stage at the front turning it into 4 channel amp. To do it I had to cut one trace and inject a DPDT switch that can engage booster circuit. It turned out great. Boosted tones are definitely brighter sounding and add lots of gain. Clean is turned into crunch, overdrive is turned into lead or aggressive metal sound, depending on the settings. Here's a quick demo, will record more these days. Played my home made mini Telecaster with DiMarzio Chopper in bridge position. Gain set to max, without boost, ISF set to 0, then the same riff with gain around noon and boost engaged.
