The problem is mate that we're unlikely to ever make something more compact because of the way we both do layouts. So I've stayed away from circuits where I have known my layout would end up bigger than something that is already available and so would be unlikely to be widely used.
This is a good example because I know for a fact there is no way I would get the layout smaller than the perf layout on Aron's site and the vero on FSB is an example of the sort of dimensions our vero would get up to. If you look at the size of the PCB for the effect on the Pisotones site, you can see that the circuit can easily get in a 1590B if you use a PCB, and that is exactly what I would use if I was going to build it.
Some things I just don't think are suitable for vero, and even less suited to the way myself and Miro do vero's in avoiding standing resistors.
You won't regret, is a funny effect. Sounds incredibly good for so few components (37) + a SPDT switch and two pots.
Yes, there are 4 IC's, but as you can see, the board is not huge, and just have 4 standing resistors, can live with that! I've tried with TL072 and TL062. Defineteky, T062 sounds better, it seems that the effect was designed very dependent of this IC. Should try anyway with 4558s, why not?
Yeah, on one hand, as you say, TL062 are without any doubt less noisy than their bigger couisins, and don't really know why, because the TL072 is supposed to be low noise version of the TL082-72..
On the other hand, as Mark says, and being a LFO built with a non usual bias (no trim as you can see), just a voltage divider it seems logical that the IC voltage was carefully taken into account for this effect design by John Hollis.
With TL062, it sounds sweeter and more round and full. With TL072, while still sounds ok, sound is sharper and gets some tendency to distort, so you get a fraction of the depth knob sweep not very usable.
