Hi, this is my first post, but I read the threads almost daily, great info on here. Ok, so here is my issue. I have an Ampeg SVT 3Pro. It's the old version with the red/blue lettering. I got it about ten years ago, used. I had the tubes replaced then. I have never really bonded well with it. So its not really been used much until recently. I now play weekly at my church and want to use the 3pro. I really want to like it, but it seems really weak in volume and just lacks something. I have to crank it up just to get something half way decent. I also have the Ampeg Micro VR, and I LOVE that tone. Its awesome! So last week I decided to bring that to rehearsal. I ran it through the same cabs I use with the SVT 3: ampeg 1510he, and ampeg 210av. Wow, what a difference! The sound was awesome, so warm and rich, and plenty of volume to keep up with two guitars, keys, and drums, and the volume was only on like 3 or 4. My band mates were like, "wow, what is that little thing" It totally kills your other amp!" So what gives with the SVT 3? Why is the little 200 watt Micro VR, totally sounding louder and way better than the 450 watt SVT 3? I read all the posts about the SVT 3 not being loud enough, and how I need to crank the gain, and push the EQ slider up. So I do that, but it's just plain weak! Why? What am I doing wrong? Should I have the tubes looked at again? Like I said, I really want to like the SVT, but my micro is so much better... I just want to toss the SVT out! Help!
