MI Audio Crunch box vero layout

[vendettav]

Hey guys, here's my first attempt to this. I did as tight as possible

The presence and some minor changes are done according to this from another thread

That layout is for the older version and is not the newest version that include the 20k presence control (which makes a HUGE difference). And although it sounds great as it shown- its still missing that extra something (a few part changes and a presence control).

However, I had noticed a few part values that differed from the actual commercial one I bought- ( of course I took it apart and took a magnifying glass to it) So after it all I found that the main differences is that c10 (.039 cap needs to be changed to a .022, the 4.7k needs removed, the 10k (r10) needs removed a jumper placed there.

The wiring needs some ajustment as well- The presence lug #1 goes to to c11 (where the 4.7k connected to it), lug # 2 of the presence goes to goes to lug #3 of the volume, lug # 3 of the presence goes to where the r10(10k) was- you can just connect it to one of the jumper legs that you would want to keep longer when placing the jumper there. As before- volume lug #1 still goes to the ground, volume lug #2 goes to out (switch),  and lug # 3 (as stated previously) goes to lug # 2 of the presence. Tone and Gain stays the same according to the layout above.

I haven't verified this, haven't even proof traced it (didn't have time)... if anybody can give me a help it'd be much appreciated

Cheers, V
