I've been using the SVT 4 Pro for about 2 months or so now...
Great amp. Can go from super clean to just enough overdriveness/distortion for me. If I need to overdrive the mofo from a bit more to MADNESS, I "KICK IN THE BASS!" with my Sansamp BDDI.
Anyway, I agree that the SVT 4 Pro might just be the amp for you. And believe me, that amp is LOUD LOUD LOUD. Especially through some efficient cabs...oh boy. (review of my efficient new cab soon to come

) Plus versatility and connectivity for DAYS. Speakons galore, the usual 1/4"s, bi-amping, great graphic and parametric EQ, ultra low/high buttons, bright button, line level control (this is super valuable for them big PA gigs), and of course, the awesome tube preamp. Takes a bit of experimenting and basic understanding of what settings gets the best personal results from the preamp and the amp overall...but when you get there, you get there.
One quick note / question though:
I hear what xshawnxearthx is saying about not being able to turn up the gain because the preamp light is clipping already. Same with my SVT 4 Pro. The max I can put my gain at with my passive bass is halfway. Any more than that, the preamp clip light gets to be more than just occasional. Any medium pluck anywhere on the low "E" on my 4-string will cause it to heavily light.
I know this is just the preamp clipping and not the limiter kicking in, but it is really troubling. So am I never to use the post-halfway point on my gain knob? That would be horrible! I want more of that tube warmth, overdriving fun! Plus, though I believe all of you that say not to worry about the preamp light coming on, the sound results that happen to my cab is definitely not pleasing.
Any advice would be appreciated...thanks for reading!
