Yeah, it's got 80's written all over it. Tight, aggressive... Whatever amp he used, sounded like he recorded it with a Marshall cab, it's got that tight closed-back sound.
Funny thing, though. I read in an interview where Warren DeMartini said he recorded the solo for "Round and Round" with a Fender Super Champ. I've got one of those amps, and I never would have guessed it. He must have used a Marshall cab, for sure.

A little dark in tone and less sustain i guess.

FUNNY!!

Please don't be mad at me for drifting away from the topic, but now that you mention Warren DeMartini, everyone ought to check out his solo effort. It's a whole new dimension. I don't quite remember the record name now, but it's something like 'Crazy enough to sing for you' or something like that.

徹底的なノイズ対策の為、安価なカーボン抵抗を使用せず、ノイズ係数、温度係数に優れた金属皮膜抵抗を採用。JRC4580D、JRC4558DD、ハーメチックタンタルコンデンサー等、高級といわれるパーツを惜しみなく使用しています。

Well the website is in japanese but I can still read the JRC4580D and JRC4558DD.... is that it?

According to google:
Thorough measures for noise, low-cost carbon resistance to using the noise factor, with excellent temperature coefficient of metal-film resistors used. JRC4580D, JRC4558DD, HAMECHIKKUTANTARUKONDENSA, said that the exclusive use of the parts to town.

According to me: HUH???

HAMECHIKKUTANTARUKONDENSA is the fella you want .....

TANTARUKONDENSA = tantalum capacitor...
at least i got something from jap classes

a little bit more on google:

HAMECHIKKU stands for hermetically...

hermetically sealed tantalum capacitors, sprague makes those

well I used 2.2 electros so we'll see/hear what I get in a few hours when I get my 4580D IC from Mouser.

Huh Audioguy...you are actually going ..how many project is on your bench now? should be at least 2 or 3 already in this week.
Great!!!...pls share your result here...

I"ve always got 3 or 4 going.

I like this one!!! Its quiet, the gain is good... not too much like other Marshall emulations. Tone sweep is ok... all in all its a good box... not great, but solid.

Is the schematic verify.?

If someone has a working layout, please send it to me!
