Jim Dunlop JD-F2 Germanium to Silicon BC108C transistor conversion.

[DrNomis_44]

Mine is a RAT2 which I bought in Brisbane only a few months ago and for my needs & purposes is just as good as the original or any variation. It sits beside my TS9 and my kit Klon clone and 5 other pedals (2 dly, tune, gate & phasor) on my current pedal board. Sadly as my power supply has only 8 outlets this means my reissue original spec Big Muff sits for the moment idle, though I'm not too fussed as there is plenty to "play" with as it is...

I built a Rams Head Big Muff pedal using a phenolic Big Muff pcb I bought online from Pigeon FX based in Hastings in the UK, the bloke who runs Pigeon FX is really pleasant to deal with, here's a quick demo of my Rams head Big Muff so you can hear what it sounds like, the four transistors I used were BC547C if I remember correctly, the diodes were all standard 1N4148 types:

The thing I noticed most is that it seems to have more midrange than most Big Muffs do.
