Если не ошибаюсь то до 70х ставили поты Mepco/CentraLab .Могу предположить те что на Хамер всё таки CTS сделанные для них а может просто тестированные-подобранные(внешне 100 пудово CTS) .У меня есть поты с гитары Zemaitis тоже CTS но со штампом GZ которые так же Земайтис заказывает для себя у CTS.
возможно так и было ...CTS pots are custombuild for Hamer ......сейчас также они делают специально для RS или Crazyparts "TVT" Pot
http://www.crazyparts.de/electronics/cts-tvt-custom-pots/index.phphttp://www.rsguitarworks.net/cms2/http://www.thegearpage.net/board/showthread.php?t=92423и это выше качеством плюс свои спецификации и разработки,в то время,и сейчас это пытались повторить RS но в силу вопроса заработать до хамера не дотянут, у тех качество было на первом месте,вот хороший трёп на эту тему
http://www.thegearpage.net/board/showthread.php?t=92423&page=3We looked at the Hamer pots when we were drawing up the specs on our new pots...
They are better than regular CTS stock for sure.
We had to tweak quite a bit to get the right taper that we wanted. And after a long process, I can now say that we have finalized everything with CTS and the pots are in production as I type this!
Our new RS pots by CTS will have a tolerance that is TWICE as tight as the current production CTS pots that everyone uses (including us at RS). Of course at RS, we hand meter EACH pot and reject MANY that don't meet our much tighter specs.
The new pots will not only have super tight tolerances, but will also be made from quality brass components instead of the aluminum they currently use (which we do not like).
Our new pots are also being made with CARBON resistance paths vs the cheaper crap they use...
Lastly, our new pots have a special custum roll-off taper that was specified by us after much research, trial and error...
It's not cheap to have a company like CTS spec out, draw up and produce a "boatload" of parts like this for us. But we feel like it will pay off in the end....
F61,на стр.4 упоминается про производителя делавший в 80х также из латуни #58
I snooped through this whole thread and never saw any mention of Bourns pots. They were kind of a fad back when people were making nuts out of brass.
