I agree. There's nothing wrong with speaking to Krueger or their distributor directly.
More than likely one of these things will happen.
1. Soundslive will repair it, bill Krueger for the repair and then send it back to you.
2. They will just forward the item onto Krueger for repair.
3. They'll take a look at it and if it's something simple and it costs less than it would to forward it onto Krueger they'll repair it themselves.
So with all that said I'd contact Krueger. Krueger as the manufacturer will be footing the bill for repair somewhere along the lines, if it be Soundslive billing them for their time or Krueger paying their own stff to repair. So it makes sense to cut out the middle man. You may find in some cases they will collect it free (It's happened to me in the past, other times it hasn't). Certainly worth a go.
