You got the 360 pre and 361 Power Plus cabinet? Nice! If you have a properly functioning one, it will take some getting used to, but they are outstanding once you get the hang of them. What you hear next to one isn't quite the same as what the audience hears. They have a big, full, dark sound. When you engage the bright button, they can sound a whole lot more full-range than you would expect from a big folded horn like that. If the fuzz works, it's a whole lot of fun, and the tuning fork is great for making weird noises, but is mostly useless otherwise. You will probably get some 60 cycle hum and all the rest of the 1960s and early 1970s character flaws. Once you start playing through it, that stuff is inaudible anyway.
They are far easier to move than you might expect, since the ergos of the tilt-back are good. A big enough car is a must. Are you picking up an original or a Grexa reissue? They are different, but not as different as you might expect. I love 'em both and play through the original in the basement at least a couple times a week. It's complete overkill for a practice amp, but why not?
