Missing the SE-10 Tuner and SE-18 Parametric EQ. If anyone has either I'll add them to the package.

You beat me :)

I suppose you bought them or some Big Jam effects on eBay?

I received the copies with some effects I bought from that seller (twice).


I also bought the service manuals for all the Maestro effects of the Total Foot Control series (designed by Moog), I hope to put them online soon :D

I bought the schematics a few months ago but needed to scan them. I kept saying to myself, "I'll scan them tomorrow". :roll:

I *think* I have most (if not all) of the Maestro TFC series stuff as well. If you run short on anything, let me know and I'll check.

I have the service manuals for the complete series, but it's a small one: only 5 pedals:

Couldn't edit the post. If one of the mods wants to take care of it...

The Space Driver looks interesting!

I got the SE-12 Chorus and I like it.

I'm trying to understand what exactly the Space Driver does, but I can't really figure it out.

I'm still just a guitar player, trying to get a little deeper into music electronic.
Could somebody enlighten me a little bit.
What about those two MN xxxx CMOS chips? Are they obsolete?

Nope. Not al all.
But refer to them as 4011 and 4007UB (so without the manufacturer specific prefix) and your search will be easier ;)
Sorry. Plain out of planes.

Thanks, Dirk.

Could you give me a little hint on how this circuit works?
I'm still new on the CMOS field...

The NAND gates of the 4011 are used as a flip-flop to command the bypass from a momentary switch.
The CMOS transistors of the 4007 are used as analog switches, again for the bypass circuit.
FYI, some DOD pedals use the 4007 to build a flip-flop too (two back-to-back inverters).

The space driver looks like a compressor combined with distortion. If you ignore all the CMOS, it will be more clear.

Thanks for sharing your knowledge.
Now I get it (partially at least).
Never really dealt with CMOS-switching before, since most schematics just exclude it.
Quite complex but interesting.
However, now the circuit doesn't appear quite as "spacey" as before.

the drive control is a bit different. i wonder what the advantage is to that configuration?
