Looks like the sales guys forgot to give out the advice to the buyers. I nolonger listen for TONE cause it's there at all volume levels. I was just playing along to malmstein, garry moore, rhoads, and i was using the same guitar and only slightly changed the amp settings to make a brighter or darker tone to match the recording sound from out of the stereo speakers at really low volume settings. I was using the vol setting down low cause I didn't want to annoy anyone in the location I was playing. yep, marshall has marshall tone at low levels. I had the best time playing the notes matched good enough, I was supprised. I'm convinced this is the best way to set the amps dials. I was using a flying V with 80's hot humbuckers. I still was able to make the perfect high treble notes to match malmstein's sound. the problem was with the middle and lower notes across the fingerboard, malmstein's notes were thinner when compared to mine. I didn't notice any difference between gary's sound and mine. I had to take away some bass sound to get real close to Mr Rhoads's sound. his solo's had more scorch to the sound. It's more important to have a great time playin, than to spend years stuffing around with trying to make 1 setting get a fictional 'tone'. The 6100 is an amp that's going to make you focus on 'tone' for too long and forget about havin a good time playin music. I think if you're changing valve brands to make one amp setting have a different sound, you're at a level of 'not needed' and it's way more worry than marshall ever intended to impose on their buying public. the guitar is a bit of bendy wood. the amp never needs huge thought levels spent on thinking about it. these channels the 6100 has, must have a simple way to set the dials for great sound. so you only need to find a volume were people can hear the sound and then the modes/whatever, needs to be adjusted in balance with the overall level. that's all you need. I was just at a street party and they had a band playing. the sound was SO F iNG LOUD most of the people just walked away and didn't come back. it was louder than malmstein. JUST bloody rediculous. I mean seriously Jumbo jet plane engines are quieter that that stupid band in the street on sunday. 80's radio top 40, at db levels louder than a 747. Mad b steads.
