In the early 80's, I used to borrow my friend's mid 70's SVT stack for big gigs. It's tone and volume were outrageous! In the past I've owned an SVT-CL, then an SVT-2 Pro, which I ran through an Ampeg 810E cab. No offense intended, but I was less than impressed with the maximum volume of either head. I even retubed the 2-Pro with NOS G.E. tubes-alas, no increase in volume. The max volume was loud but not clean enough for my taste. After my stack started gathering a lot of dust I sold it. I'd still like to have an all- tube head for that awesome tone. I've tried the Boogie 400+,it sounded great and compared quite favorably side-by-side vs an SVT-CL at my local G.C., but I've always been a fan of the Ampeg tone. I remember my friend's vintage SVT had tons of headroom, volume, and was a very clean sounding amp. I'd really appreciate opinions from owners of vintage SVT's: How does the tone & volume of the SVT-CL compare to your vintage SVT? Or should I just buy the Boogie 400+? Thanks, A.P.
