It’s a pretty crazy mod to be honest, trying to implement it over the weird circuit Marshall has going on, and hard to impossible to find schematics of the amp. It took me over an hour of just staring at the schematic and thinking how the fuck am I going to do this lol. Then it’s all the removal of all the components that need to come out over the tube sockets it’s a pain in the ass. It’s alot of work.
Shea mods sound absolutely killer and his videos inspired me to mod my own. He and Jason are awesome! Really want to try both there amps.
Here is what the amp came out as ?
Could you possibly share the Origin 50 Schematic? I’m trying to troubleshoot one and I could really use the schematic Thanks!
 
Hey guys,

With the help of Jason’s (headfirst) videos and the info posted on his website I was able to mod my Origin 50 into a ripper of an amp for less than $600. This thing has such a great feel as tone and I don’t think for the money it can be beat. I used some schematics and pictures online as well as my own amp. So it’s more of a Friedman JJ-100, JJ Jr. circuit, with added resonance and focus control. The pull boost feature engages the clipping and where the tilt knob is the focus NFB feedback control and removed the power scaling, so it’s in high voltage all the time, then in its place put a resonance pot.
What is surprising is how cutting and aggressive it is in the upper mids and top end and just has that perfect, in my opinion Marshall style modded type el-34 tone. Granted without the clippers in it’s basically just a BE with 3 gain stages, with just enough gain.
Check out the clip and see what you guys think of the tone.



That sounds fantasticly killer !
