Question about LM308 and Giant Hogweed pedal

Postby Philtre » 08 Jun 2018, 20:12

Hi,

I'm building the Giant Hogweed circuit at tagboardeffects - http://tagboardeffects.blogspot.com/201 ... gweed.html

The schematic is here - http://www.davidrolo.com/wp-content/upl ... 5f5a36.png

I've got all the parts except for the LM308 chip. But I'm having trouble finding one. Could I use an alternative? I see them on eBay but I'm not sure whether they are fake or bad quality.

Thanks!
Philtre

Hi,

some manufacturers use OP07 instead of LM308. For example:
