Ok here we go,

I have posted here a few times with questions about my 6100lm and have had great feedback. I am still unhappy with the sound. I had new power tubes put in and biased and had a tech go through the amp a few weeks later and replaced a couple of the pre-amp tubes. I am running a 1960a cab with the 75 watt celestions. This thing sounds so sterile to me. The only way I can describe it is there is no give. I have a 5150 combo that I played this weekend and had my 6100 next to me with my twin brother playing it and it was scary. The combo with two speakers had more lows more sustain and more usable gain. The low end on the marshall sounds flubby to me and there is a noticeable lack of sustain.I have been running channel two with the right button pushed in with the gain around 6 and on pentode mode at 100 watts when playing outside and 50 watts inside. What am I doing wrong? I am very close to putting it on craigslist or ebay and trying to get my money back out of it and going for an 800. I play mostly 80's type rock Dokken, VanHalen, Tesla, Ratt those type of tones. I thought this amp would nail those tones. HELP!!!
