For the past 6 months I've been having problems with my SVT-2 Pro that nobody seems able to fix. A while ago the tubes went (quite obviously so) so I took it in to get serviced, the first show after the service however the output sound was noticeably much lower than normal, in fact I even though the bass wasn't working until I boosted to volume. See previously I'd never had to boost it above 1/4 or 1/2 volume to shake an entire room down. So I took it back to the person who serviced it who was ridiculously dismissive and basically said "it sounds loud to me" he's sort of a small coffee shop/restaurant musician and it was too much of a struggle to explain to a professional amp repairer why it's not normal to have to turn my amp most of the way up to fill a room.
So I used it for a few months until my last gig where the soundguy told me my amp was way to quiet, I had to put the master volume on full and turn the gain up to 3/4 and I was contemplating boosting every EQ knob to try and squeeze more volume out of my amp which ended up being barely audible over the guitars.
So I took it to another person to service it, turns out all the tubes were gone which was strange given I'd only used it 3-5 times since the previous service where they were all replaced. So after purchasing a whole new set of power tubes I've got it back again and the volume is still absurdly low. To test I turned the master volume to full, the gain to full and the gain on the graphic EQ to full and played it through my Ampeg 810. Now it wasn't quiet by any means but at that volume it should be shaking every window in my house and giving me permanent hearing damage, instead it sounded like metal band gig volume. My friend whos a local soundguy confirmed that theres no way it can be working correctly if it's putting out such a low volume.
I've used multiple different cab and bass combinations as well as different cords, tried connecting through both 1/4" and speakon. The amp has to be the problem. The last technician who serviced it confirmed it was definitely outputting 300w and there was nothing wrong with the output and I am completely lost as to what the issue might be.
My only observation is while the peak light next to the gain control used to almost constantly flash when I was playing I now need to turn the gain up to full and boost every setting on my active bass and play HARD to get the light to flash briefly, it's almost as if there's a pad constantly on the amps input but I've taken it to two technicians and nobody can find any fault. You don't ever really see big Ampeg rigs and it seems like no technician will believe me when I tell them theres a fault with my amp, they all give the same thing "it sounds loud to me" "that light shouldn't peak with new tubes" I'm even starting to doubt myself but the evidence is there. I should not in a suburban home be able to safely turn every knob on an Ampeg to full through an 810, this is a freaking loud amp not a small gig rig.
So what do you think TB, does anybody here have any ideas what might be up with my amp and how I might fix it?
