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.
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.
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.
