So I just bought a svt-4pro yesterday but last night I played an audition on someones elses SVT-Pro 2 and I loved it. I called guitar center a sec ago and they said they had one SVT-Pro 2 left and it was only $999 cause it was discontinued. Thats $150 less than my 4pro so I'm thinking of doing a trade but was wondering when the 2pro was discontinued? I never heard anything aobut that, any idea why? You guys think I should do the trade? I was comparing my 4Pro's tone after last night and I really want the tube growl I was getting with the 2Pro. Also, I was curious if the 2Pro was as noisy as the 4Pro? I'm getting pretty loud fan noise and also hiss if I turn the treble up on my 4pro.
