ADDED ANOTHER MOD ON MY BLACKSTAR FLY 3...........

[Jeffblue]

I had already modded my Blackstar Fly 3 with a more efficient 4 ohm 3 inch Neodymium speaker and added a pair of Schaller strap lock buttons (so you can wear the amp using a guitar strap) The speaker upgrade made this amp sound huge for it's size and much louder.

Today I added a speaker out jack. This little amp sounds outstanding through a larger speaker cab.

I put a speaker out Jack on a 20W 1x8" fender modeler combo once and was amazed how much better the amp sounded through a different cab! Sounds like you've got a good little setup there. You can't get much more portable than that.
