I recommend step volume control do not be with a large total resistance of 25k.
Тhis is my opinion and it may change in different situations.
As for the price of my 24 step, for information;
Price for one piece аttenuator; 28$
price for Shipping, normal post to Chili: 6,5$
PayPal taks :1,5$
[b]Total: 36$[/b]
Everyone chooses what is best for him.
