Thanks! But maybe dont you think it's still too big? SMD maybe?  :) Also as I posted I noticed that the clearance is just too tight  :o

Oh yeah, forget about it thanks alan!  ;D

Thanks for your appreciation!!  ;D

Btw, I found the traced schematic of belton btdr-1 in the russian forum ( http://guitar-gear.ru/forum/topic/3578-belton-btdr-1/ ), here is the hand drawn schematic in that forum by Новичок/saha

(Please follow the link above if the image is not showing, the schematic is in the page 3)

The schematic above is not working really well, the result that i got at the first is just crazy oscillation. But after change value of some component, it's working well. Here's what I change:
1. Caps between 10-9 pin of the pt2399 by 47n, 47n and 10n for the 1st, 2nd and 3rd
2. All the weird R value change to nearest value (4k9>4k7, 11k8>12k, 3k94>3k3)
3. R at the VCO pin of the 3rd IC to 4k7
4. R between the input and the output of summing op amp to 6k8

I used 741 for the summing amplifier and 74HC14 for the schmitt trigger, now I'm designing pcb layout for it and maybe will change the schmitt trigger IC to the relatively small op amp, also I will try to find the best op amp for the summing amplifier which enough powered just by 5v supply  :D

...Also I'm not sure if the decay of the reverb actually control by the feedback at pin 12 or it's the VCO of the pt2399??
currently I'm busy with the other work, so I have not been able to continue this  :'(

this is my built of ezekiel, please enjoy!  ;D
..but I think something wrong with my built, somehow the silicon diode clipping selection give bypassed signal  :-\
