Fuchs Plush "good vibrations" reverb foot pedal from 2009

"You don't belong here" printed on the overlay- so thats why its fuched. Proudly says RoHS on the casing, rustling noises at random, so fuched by RoHS probably, certainly PbF solder. How to get under the scrappy looking black "conformal" coating. Not epoxy coating as methylated spirit softened this plasticky coating enough to scrape off with a wooden cocktail stick on the Main chip Spin FV-1 , nice to see datasheet for this on their site , and also 5532. Seems suspect solder on a pin of the main chip, from twizzle sticking. But what is the cleanest way to get the coating off - it hardly looks pretty as it is, am concerned about meths migrating capilliary fashion along the pins, to deal with the underlying pbfitis. Chemical reaction between this black stuff and solder?

wire brush in Dremmel then scalpel between pins and then needle, hooked it off quite cleanly.

not vibrations but good verbrations , whatever that is What an overpriced heap of junk. On pulling off this rubbery plastic film one of the SM caps came off with it. The film is not stuck to the components with any force, a needle under it and it lifts quite easily off pcb etc except where its lodged between IC pins. The SM C&R near the main chip that I had wire brushed were firm enough. Poor PbF solder under pin 22 was the main problem but what else lurks under the rest of the black stuff I've not touched? Standard die cast box with no bumpons under to stop it sliding, no separate battery housing so you have to fully open up to replace battery . The power socket loose and no 1/2 inch 25 TPI bush nut available this side of the pond, to rob off something, to replace it, maker had hand filed out hole in the box to receive the socket (because of flats). Looks as though I'll have to continue the spirit of bodge, with hotmelt glue inside to keep this socket in place.
