Jonathan- I moved the topic to the Gear Board as you'll probably get more responses here.

I'd probably opt for the Spider amp as personally I think the GT10 would be mismatched with the Laney amp you have at present. Unless you intend to connect the GT10 to a good pair of active monitors or a different amp- if you did that then the GT10.
One thing to consider as well - the GT10 is a
lot more expensive then the Spider - so perhaps you should look at a few other possible amps that are around the same price range as the GT10 MFX... Just a suggestion though
.
Cheers,
Tony
