New Colorsound Tremolo PCB

[SonicVI]

I've only seen stripboard layouts for the Colorsound Tremolo so for anybody interested here's a pcb and layout.  I have built it and it works. The schematic specifies linear taper pots I believe, but I think reverse audio spreads out the range much more evenly.  Transistors can be BC549C or anything similar (2n5088, 2n3904, etc). I used BC184C and they work fine. Lowering C4 increases the speed. I used .22uF and it's plenty fast for me.  The size fits a 1590N/125, but could probably be reduced down a bit to fit a 1590B.  This is one of my first pcb layouts so please forgive any amteurishness.

REVERSE AUDIO!!!!

I was wondering how to remedy the squashed response in my stripboard version!

Do you have unity gain issues?  My CST is a hair quiet and I was thinking of reboxing it with a gain stage.
Now that I'm going to order some new pots for it that makes even MORE sense!

I first breadboarded it with a switch to check for unity gain and it with a clean signal it seemed the same to me, with distortion it might be another story.    I had a reissue CS tremolo and it had a very noticable drop, but it's a different circuit.

I've updated this layout for better component fit for the capacitors and I added pads for a trimpot to replace R4 which can fix the volume drop problem.
