Nice little thing, I presume its one of those cmoy jobs?

Not much to mod tbh, you could try another op-amp, one that works well on low voltages and has decent output drive

no difference to be had by changing any of the other componants?
these cmoy things are pretty limited are they?
a mate of mine has offered to machine a case for it out of a block of anodised aluminium maybe in a funky purple colour. so i thought if i was going to get him to do that i might as well make it as good as possible first
