This is key. The BBD chips don’t run at 24v, the focus on that is weird for the perspective of the final sound.Big Box runs on -15V. Regulated down from the unregulated 24V adapter that puts out 30-ish volts unloaded.
In this nano 9V will probably be stepped up to 15V.
As for modulation:
The big box and XO version switch between 2 capacitors (2.2µF and 470nF) in the LFO giving a slower 1Hz frequency for chorus and a faster 4,3Hz for vibrato.
Instead of switching between capacitors you can also vary the resistance (910k) on the inverting input of the second opamp of the LFO. Around 200k will give you 4,3Hz and 910k gives 1kHz.
Rate pot at minimum is chorus and at maximum vibrato.
I personally don't see a need for the inbetween settings. The chorus will be too fast and the vibrato too slow.
Believe it or not but the Memory Toy is the same circuit as the Memory Man, only adapted for those 'crappy' 3205 bbd chips. Some controls are left out and set at a fixed value internally.
Great comparison. It's funny, listening to them blind, I like the Nano more. There is some difference between the two, but not much to be a game changer.Because I'm bored, I extracted the audio from the comparison section of the video, put a touch more time in between them and looped it 4 times.
As per the video - it's XO first followed by the Nano.
I'm no audio expert, but looking in my DAW the waveforms are slightly different, but I assume that's to be expected between 2 different pedals?
- tails (vs repeats that stop the moment you hit the bypass foot switch)If I don't care about size or plug type, why would I want the nano?
sold- tails (vs repeats that stop the moment you hit the bypass foot switch)
- 1M Ohm input impedance (vs 100k Ohm input impedance)
- modulation rate control (vs choice between two fixed rates: chorus and vibrato)
- daisy chaining to other +9V pedals (vs separate, reverse polarity 24V adapter)
Have they mentioned anything about the internal voltage?I asked EHX about it today on their forum.
Well one of us is going to have to shoot comparison clips.............You hereby have permission to buy this, as well. We will support that decision.
Its false advertising really. I dont know in which situation "tolerances" would cause 37.5% difference, so i still dont understand why its advertised as 550ms.must be very rare to have the one that is! I cant say i understand this circuit but i know components that have 10 or 5% might be more common.I asked EHX about it today on their forum.
Doing the math based on component values in the factory schematic (which matches my actual pedals), the maximum delay time is 409,6ms. This is also what I measure and what most people report:

EHX look like they're responding to posts on this page:
"It is fully analog, just like the original. It's effectively the same circuit as the OG Deluxe Memory Man but with added buffering, Tails Mode, and both Rate and Depth controls for modulation."
