I've gotta say, the innards of mine don't look terribly robust. The pots, switches, connectors are all pretty cheapish, and there's very little clearance between the bottom of the board and the case. It wouldn't take much to knock a connection loose or short something.

I used to run one in my FOH rig and also had one in my bass amps effect loop. I loved how it sounded on vocal delays. Dale from Acid King (also Melvins) complemented me once on the vocal sound I got with that.
On bass it was a neat flanger, plus you could hit repeat hold and walk off the stage as the drummer kept smashing into oblivion while your amp is cycling up and down the repeat.

I'd like to recap it, add some memory, and build a pedal for it.


..and then post copious notes and photos about the process. Very Happy


guts of mine (sorry for the widthiness!):




the red tube is the battery for the memory, which on mine still works.

i think it has been replaced a few times on this unit.

Don't know if this has been posted yet either:

http://home.debitel.net/user/jhaible/jh_adm1020_loop.html

Basically, you're looping the data stream from the RAM back into itself to create and infinite loop, but you're also piggybacking another set of RAM chips, so you can send data into those as well and create longer loops.

I think the procedure would be the same for the 1024. I'm going to try it with my 1020 at some point. Finding those RAM chips may be difficult though. May have to scavenge them from something else.

can anyone recommend a suitable replacement for the internal battery? Or could I just replace it with a jumper?

I'm wondering if anyone here can give me some info. I have an effectron, 1024, not the effectron II. I am currently trying to get this unit up and running again. I am not at all sure what is wrong with it. I have schematics but they are for the Effectron II. Apparently there are some differences between the effectron and the effectron II as looking at the schematics and checking values, particularly on resistors there are some differences. Does anyone here have the schematics for this model. Effectron ADM1024? So far I have swapped out the two large capacitors in the power supply section given that they are over 30 years old. Have checked some of the other components. What would be particularly helpful is the parts list for this unit. Mfgr. frequently include this in the user/maintennance manual. If anyone here has any info it would be most appreciated. Thanks
