Another scan for you.

This time it's schem for an old Tascam GS-30d Guitar Amp Simulator.

A little weird this one. It's from about '89 - '91, and it was the first time I'd ever come accross the concept of speaker emulation for recording.

I remember the review in Guitarist magazine here in the UK saying it was quite good. In reality it's quite crap. Which may be an early 21st century pair of ears revisiting the thing after a decade or so.

The clean sound is fine, with useful presence and gain boost options when needed. The boost is almost always needed as the 2 outputs are both attenuated, If I was going to use this I'd modify it so that at least one output was a healthy line level.

The distortion sound is useless as a direct recording "simulated" sound. For all the circuitry it sounds like a distortion+ plugged straight into the mixer. No evidence of tonal shaping at all just fizzzzzzzz.

Still it's an interesting schem and may give somebody ideas.

Thanks very much - some of us bother to look at new scans & circuits people bother to link!
