DSL40CR low end a bit flubby!

All Questions

I recently bought a new DSL40CR. Great sounding amp! Great tones! I am noticing that the low end sounds a bit flubby. I was reading in some forums that this can be caused by improperly adjusted BIAS. Can anyone direct me as to what the mV for each left and right tubes should be set to?

I bought the amp and live in Canada. I have been searching for a service tech of authorized Marshall service depot in the area(Sudbury Ontario). I bought the amp from Long & McQuade Music in Sudbury. I understand that the test holes and trim pots are there for consumer adjustment. Please advise further. - 07 Mar 2019 at 01:56 PM

Thanks for the NON help. I had heard that Marshall customer service was shitty. I guess I heard right. I fixed it.

If I lived in the UK would I have gotten better service? hmmmmm The questions we ponder.

Hello Todd,
With regards to your comments as company we are unable to give you biasing information as we have to advise it is carried out by a qualified engineer due to health and safety regulations. This is the same information we give regardless where the customer is based.
