I don't have the Shuttle, but I do have some other items. Email pics available on everything.
1. Ashdown Little Giant 1000. NIB, never played, 1st quality, not 2nd, refurb, blem, demo, etc... Bigger than the 3.0, but at under 8 lbs. it's still very light. It's certainly more powerful, 500 watts x2 @ 4 Ohms (or 375 x2 @ 8), like 1000 @ 2. If you only need one side, you have the ability to power something else with the other.

2. Euphonic Audio iAmp800. Minty w/rack ears & 2-space soft case. This is a full-size, 2-space amp. Great tone shaping control. At 19 lbs., still on the lighter side of amps, just not a micro. 1000 watts @ 2 Ohms, 800 @ 4.

Also have a mint 4-string fretted Cort Curbow w/Bartolini PU in CAR and ~25 As New effects pedals.
Let me know if you'd like to discuss anything.
