[sdiy] dynacord vrs 23 mod

[floppy]

i like the sound of this device but it feels like there is a lot more 
possible with it especially in the modulation section.
does anybody know about a mod to  increase the mod freq and the depth ?
maybe its also possible to extend the delay times in both directions to 
get more into flanging and longer delays.
finally the tone pot could be 20 times stronger to my taste and a switch 
for routing sweep freq to modulate the
tone would be VRS2300 that im dreaming of.
