I bought the amp in 2008. Originally it was a Signature 30.
Comes with manual and invoice.
I am the first owner.
Vinnie Rossie performed an upgrade to 30.2.
Unforunately, the amp came back with a malfunctioning remote control mechanism.
The remote control is still working. It is the internal remote mechanism that causes trouble.
If you are a technichian, then you should have to be able to perform the necessary repair.
The battery is still brand new and I have 2 new spare batteries which I would like to sell for half the price.

There are many reviews of the Signature 30.2.
