Yerasov Gamma DS-1 Distortion

Old Yerasov Gamma series distortion. Box totally looks like a Boss rip off, but the insides are not.

Info about the original:

The Yerasov 5000 Volt Modern Distortion in rugged aluminum housing provides official nu metal high-gain sound and offers the following control options: Current (Volume), Insulation (Tone) and Voltage (gain). Power is supplied via the optional AC adapter.

The official schematic calls the tone control "Isolation" which is what I have also named it.  Insulation may make more sense though, but call it whatever you like :)

Yerasov 3000V

An interesting alternative to the usual Tubescreamer clones and similar, this is an overdrive pedal from Russia and sounds pretty good to me.   I can't find much of a description, even the manufacturers website seems to mention the mechanical side rather than any sort of description of the circuit, so I'll let the video tell you everything you need to know.  And a bit more info if you speak Russian.
