archer and zeus are Klon copies not TS style pedals, completely different circuit topology.
still I don't think it's a good idea trying to burn your pedals with higher voltage than your internal caps could stand, is there anyone near you practical with a solder? the cap upgrade is cheap, with max 3€ of components your pedal would be bullet proof, I don't see the reason to throw away a costly pedal by deep frying, they are not even usable when broken to block the doors, too light..
if you want a higher voltage supply TS style without messing around with soldering iron, get a EQD Plumes, it's a TS style pedal with internal charge pump to 18V but you use a normal 9V to supply it, that's a clever solution, high quality components too.
BTW, archer and Zeus HAS the same internal.charge pump , internally they work at 18V., so never used (never) a 18V with them because the internal voltage ramps up to 36V.....
