Just picked one up today. It came with the alnico blues....I couldn't say no to it as she was selling it cheap. This thing sounds so good with the blues. I really am stunned as I've had a ac306tb and didn't like it at all. Should I even bother upgrading the tubes or what? I like the idea of perhaps doing the mod that effects the high end treble. I'll have to look into that. Coming from playing a deluxe reverb, this thing sounds huge!!
