Total Recall + MV-64 = success !

[archaos]

Guys,

I've just finished my second Totall Recall, and managed to get it working properly when controlled by a Delaytion (like did Brian with the Timelapse, I guess).

The Delaytion buffer needs to be somewhat modded (attached) so as to match 4047 voltages (attached), 2N7000 removed and swapped with 2N3906 ; 330R gate resistor replaced with 1k8 emitter resistor ; 10k collector/4047 resistor tied to -15VDC added).

Furthermore, the modulation depth control ought to be modded as well, otherwise it can quite tricky to use because the settings sound way too extreme and weird. Indeed, with just a little CW rotation, 'the depth dives too deeply'.
Hence the adding of a 150k resistor in series between the 3rd lug (hot) of that pot and AVDD (3.3V).

Enjoy !

Hi Pierre... What does this mod achieve? Sounds interesting

Now that's exciting! Would love to see some pics!

What does this mod achieve?

That mod actually allows a -15VDC Deluxe Memory Man (or clone) owner to use the Delaytion with his stomp.
The Delaytion has already been said to work with MN3005s powered with positive voltage, here for instance : http://www.madbeanpedals.com/forum/index.php?topic=10889.msg102950#msg102950, or there : http://www.madbeanpedals.com/forum/index.php?topic=23970.msg234450#msg234450

Yet, I found that it didn't work when I connected it to my Total Recall 4047 (pin 3), because instead it muted the signal of the pedal.

Now that's exciting! Would love to see some pics!

Unfortunately, I'm on holiday and away from home for the moment, but I might post pics within a fortnight.

Thanks for the info
