Second thing - gain pot should be 2or 5 kom max!! Just do it, people! look at my changed scheme here: https://imgur.com/TU07btDZZOYDhttps://www.blogger.com/profile/17557567967251809829noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-29758208415570770802021-03-19T13:23:30.064-04:002021-03-19T13:23:30.064-04:00A SPDT is fine.

Only part sub was 220nf cap. <br />Voltages at trannies are:E-B-C<br />Q1 9.1 8.3 0.0<br />Q2 6.8 6.6 6.8<br />Q3 9.2 8.6 0.0<br />Also, FWIW, I am getting continuity between the input and ground. That does not seem right? <br />Thanks!MJ n' Johnnyhttps://www.blogger.com/profile/02958705680256831290noreply@blogger.comtag:blogger.com,1999:blog-5481402030233340127.post-33897513583453382552019-02-07T16:33:45.091-05:002019-02-07T16:33:45.091-05:00Works great, thanks a lot !

Turn your guitars volume pot down and you can get some great tones out of this. You should build this. I built mine with NOS 2n408s and bat41's cause I ran out of 1n34s. Have some on order so will report back once I receive them. Another great layout brotha!!! Anonymoushttps://www.blogger.com/profile/13264977576995795605noreply@blogger.com
