Hi
I'm new to this group. I just randomly found this site. I have been building and fixing, modifying pedals since the mid 1970's
Here are some guts.
The wha is a Vox847 or 846 I got in a trade. It wasn't working and I fixed it but the old transistors were noisy and the electrolytic cap was leaking foamy stuff.
I finally decided to rebuild the whole thing. I only re-used the inductor (no it's not a Fazel its a Stack of dimes) I built it "dead bug" style over a ground plane. I used some NTE low gain transistors, Wima polypropylene MKP10 caps, metal film resistors, and Mogami shielded wire. I also added the output buffer circuit as to properly drive a Fuzz.
The other is a "Green Ringer" I threw together on perfboard. and put in an ugly pre used case. I'm not going to use it though I don't like the sound much.
. My next thing is to build a Roger Mayer Octavia.
