Sanded IC's intriguing Looks like a EHX Metal Muff. The fact that the Boost feature is almost unusable due to the extra Treble and Noise added also makes me think its a Metal Muff.
Anyhow just for the record here are some pics

Isn't the Metal Muff fairly simmilar to a BOSS HM-2 or MT-2... I don't know why but it seems less likely to me that they got the EHX schematic... maybe it's just me as the boost feature does give it away some.

No, there are quite a few. All of the Tech 21 rip offs are SMD also.

This doesn't look like sanded to me, just dirty with flux residue.

Good day forumite,
Here's a mod that you can apply to extreme metal with great result. Extreme metal has the same distortion circuit with metal muff and boss mt2 with fix mid freq and additional boost circuit minus fet switch.So I try the mt2 no nasal sound mod. removing two capacitors C2 and C10 using cutter or nail puller.
here is some sound sample
the distortion will be dynamic and its more marshallish tone with great bass. the boost now makes the mid more pronounce or making it metal but still dynamic. This mod can be used at metal muff. good luck.

Hi, I started building a digital clone of the Extreme Metal
and found that it is not as easy as I thought... Cod someone help me what's going on inside? There seems to be kind of parallell distortion to keep the Bass tight. I'd just need to understand the basic concept, the rest is earwork ...
