2 weeks agao I bought the SVT-3Pro head with the SVT-HLF410 cab. Wow. That was a beautiful sounding rig. Extremely juicy and punchy with plenty of growl or top end silk. Problem I had was that it was slightly underpowered. Not radically underpowered but it would have been perfect at about 600 watts. I returned it to the store and upgraded to the SVT-4Pro. So now after after 4 days, I am getting more and more dissapointed in the tone. The 4 Pro has the power to spare but the tone is gone I have heard that the 4Pro and the HLF 410 are not a good combo. I have to agree though I think most of the trouble is with the 4Pro. I Have heard that the 4Pro does well with 6X10 cab. Which is rated at 8 ohms and is more of a 'short throw' cab. Less bass response than the 410 but a better match. I COULD get the SVP but which power amp? I have heard that crest and mackie are my 2 best choices for 'tone' power. Any input would be helpful. This 4Pro is heading back to the store. Dissapointed.
