Cheers folks.
Aye, it's a great amp. The only negative is the weight - it weighs about the same as I do! Lifting your own body weight up two flights of stairs is not fun.
It looks so darn nice though - thinking about just keeping it in the flat as eye candy.
I think I have finally decided that Ashdown is the sound for me. I have an electric blue 1x15 combo, a recently aquired ABM 2x10 combo and the Klystron 4x10 combo. I'm trying to justify keeping all three - an amp for any eventuality is what I keep telling myself!
Also, I have three bass guitars so if I got rid of one of the amps then surely that would ruin my equilibrium? . . haha
