Since posting the SEPlex design a few people have built it and I’ve heard that it has, what might be considered, excessive amounts of gain. It does have gain since I wanted EL34 OD sound but I thought it would be appropriate to have the option to tone it down a bit.
So I changed the boost switch around. Now the “boost” setting is what used to be the “normal” setting. There is now the option to add a voltage divider after the tone stack. So, between the gain control, master volume and this, you can control the gain after every triode.
This clip is using what is now considered the boosted mode
