Im looking at one on Ebay

http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&ih=006&sspagename=STRK%3AMEWA%3AIT&viewitem=&item=160072829809&rd=1&rd=1

Firstly, how much do you think its worth?

What is your opinion of the amp, what tones can it do and can it do metal with a decent OD pedal?

At 30w will i be able to crank it in my bedroom at reasonable volumes?

they sell for 600 USD new, It's definitely not a metal amp and it is loud for its size so don't plan on cranking it up in your bedroom.

Great amp, mine was $320 on eBay. I wouldn't go over $400. And yep, it can do metal with high gain tubes and an OD.
I'm not very active here on UG currently.

You can't crank a 30w tube amp. Even in a band you won't have it up to 10.

EDIT: I don't know if $670 is a great deal. Apparently you can get them for $750 new at Davis Music in Melbourne, but maybe not in NSW.
