I have got a Studio 1 brand dual proc amp. I do not want a dual one and would prefer a single one as i don't think i need the dual version. Is there anyone preferably in USA who would be prepared to do a swap (double for a single)? I don't care if my double is of more value and i will not be seeking extra money to make up teh value, all i ask is that its in the same condition as my double amp. I say USA only because the proc amp is in USA at the moment. I am in Australia. If i can do a swap with someone in USA before i ship the unit here it just works out better that way.
