We bought one t.amp D4-500, after like 4 weeks delivery, we finally got it.
Just to notice that only 3 of 4 channels were working.
Called Thomann, they would take it in return, but would not send a replacement before they received the broken one.
They also told us that they would cover the shipping costs, but even if we have sent all required documents regarding this, we still have not seen any money, now it's been like 8 weeks, still no money.
Well, it's only like 50-60$, but as it seems like now, it sure looks like theft, but what do we know.
Anyhow, last week the new replacement amplifier arrived, and guess what??
Yes, this one has the same error, only 3 of 4 channels are working, so now we have to send this one back to Thomann as well.
Never again will we do business with Thomann, bad products, bad service, and they will not pay back our money they own us.
