I just bought a WT-800 and it's an AMAZING amp. I love it. I have some quick questions about it though so i can get the most out of my amp. 1. The frequency knobs on the top of it (3 of them) they dont seem to change my tone that noticably if at all. Should i be able to notice it if the mid is all the way at 8 o'clock then if i change it all the way to 4 o'clock? 2. I also bought an Ampeg PR-410HLF cab (600 watts RMS @ 4 ohms) The 800 has plenty of power for this cab... if not maybe too much with the active EQ. I'm worried about blowing a speaker or damaging my cab... should I be very cautious or am i good as long as gain isnt all the way up and bass and low range up too? 3. (last question) I'm trying to find the best way to get maximum output on my amp without clipping. I get most of my volume from my gain and not my master, but my master is what controls what the cab gets. I also notice that when gain is up the compressor light will flicker a little bit at my strong attacks. Should I not fear the compressor light at all? I know to fear the output lights. Would i be ok if i had my gain all the way up and my master way down? thanks for your help!
