Well like I answered to ya in the Youtube PM, I don't what the specs on your LittleJoe
Mind discribing it to me? (how many channels, switches etc..)
Mine has a switch in the Clean channel, if it's on then it "breaks up" it's beautiful for blues. because if THIS feature, I'm making a double amp rig (Diezel & Little Joe), just so I can have it available for my "bluesier songs". If it's off then it's the cleanest of clean with a lot of headroom (for a 20 watter obviously).
I must tell you this though......give it some time..... you'll get used to it. The amp's clean channel is VERY responsive and unforgiving, it feels dry even, but with time you'll adapt your playing to it a bit and it'll be glory (at least to me it is) Add some delay and reverb to the clean channel and you'll be in heaven.
