Gentlemen !
To give some light into the discussions on this
and other boards:
I never came up with a mark 1 or mark 2 or mark 2.5 version.
This was an idea from Eddie Yoon, former owner of tone merchants.
The very first 30 Herberts sound different.
They have a fast attack, but not a high amount of
low end. If You like that, You are happy.
From # 30 to # 781 You can hear a small change
in tone towards more bottom end. We spent external
tube fuses and fault LED´s during this time.
No Herbert user has to have fear, that any Herbert
sounds light years better.
Sure, there are small differences but Your cab or guitar
makes more influences that made by the changes.
So it´s not necessary to ship Your amp to California
or Germany.
If You are not satisfied with Your amp we are here to
help You out. I´m two times a year at Uwe´s office
to make repairs and modifications.
