Plus, it makes my fuzz pedals more noisy. It is lovely with just a clean sound though, and also really enhances my tubescreamer, so I'll probable keep it for certain situations. Thanks for the layouts on this page... I've made three from this site so far and they've all worked first time!

Instead, if the buffer is in front of an effect, the 50k does not go to ground but connected in series between the 150R and the output. It's right?divanorossohttps://www.blogger.com/profile/08135645331262940027noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-58986513895503303352018-03-22T11:25:50.760-04:002018-03-22T11:25:50.760-04:00I thought about doing this.

I always make sure to have this at the beginning of my chain and at the end on the way to the amp.

The same lug of the switch the buffer Out is wired to would connect to the In pad of whatever effect you're using and the Out pad of that effect would connect to the switch where Mark's drawing says "Vol 2". Hope that helps!Effects Layoutshttps://www.blogger.com/profile/11341183658959824998noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-80268585017167112722016-03-21T10:26:20.917-04:002016-03-21T10:26:20.917-04:00I am really excited to see this buffer.
