From the post

Another layout and a dsign for those like it heavy by Chris at CDC Fx. No blurb from me, Chris does it better: Things are rainy and depressing here in California. And also depressing in the world, in general. So I've been drawing more layouts.

I was inspired by both the Dead Air Sawzall, and the layout another Dirtbox user submitted to you under the name "Glass Jaw" - with a Bax EQ in the middle of the two LM386 stages of the Acapulco Gold.

So I came up with a modified Acapulco Gold circuit with a better gain control (instead of the common mod of a 1m pot on the input, this one adds up to 10k of resistance between pins 1 & 8 of the 1st LM386) and "sandwiched" (hence the name, hah) an HM-2-style EQ in the middle of the two stages. I'm also running this at just under 18v with the onboard charge pump. The result (I just built it, so it is verified!) is a a pretty versatile amp-in-a-box with Sunn tonality and a switchable 3 band EQ! Not at all "chainsaw" but really cool sounding nonetheless! The TO-92 18v regulator is probably unnecessary, since the TL082 can handle more than that easily, but the LM386-4 is rated to max 18v and I didn't want to risk damaging them.
