I have a classic 50 2x12 that I retubed with JJ tubes frome www.eurotubes.com . They work great for me. As far as effects go, I use a boss CH-1 Chorus, and DD-3 delay. The CH-1 isn't all that versatile, but it does exactly what I want. I also use an MXR ZW-44 overdrive pedal that is awsome! In front of a clean channel, it gives a great transparent bluesy overdrive, and in front of an already dirty amp, it can get very brutal. I like it because it doesn't cover up the tone of your guitar or amp, it just adds to them.
