    I had a quad box 35 years ago and yes they do sound better but man what a pain to move around. Going up and downs stairs at gigs really needed 2 people to carry it but being young and stupid did it on my own most of the time. Thank god I never dropped it as I came close on many occasions.

    Lucky you have a Master Volume model as you can crank the pre-amp section and drop back the power amp output to bring on the traditional overdriven Marshall signature sound. Funny thing is, if everything is wound right up I reckon with master at about 3 or 4, going any higher may not sound much louder just a hotter sound. Problem is on a 100w anything past 2 is extremely loud or at least that is what I experienced on my old Marshall amp.

    Yep, those non-master volume Superlead Plexis tended to get very loud early on when you turned them up past about 2 on the master volumes, this made it hard to get that classic crunch-tone at lower volumes, I might do some experimenting with the overdrive and master volume settings on my Marshall tomorrow, I usually keep the master volume around the 9 o clock position and then play with the overdrive setting, i tend to keep the Crunch Balance control set full-on, all tone controls were set to the 12 o clock position in that new demo I posted, that's a good test for an amp, if you get a good tone with all the tone controls set to 12 o clock, you'll know it's a good amp.

    I've had a great time re-familiarizing myself with my Marshall amp so far, been feeling really eager to get back into gigging mode again, my mate reckons there's going to be a gig coming up in September in Darwin at a place called The Railway Club, he wants to play the gig with me and some friends of his, so we have some rehearsing to do, he and I have been getting together a list of songs to play at the gig, in the meantime I have been doing some work on his amp rig and once the mods to his Triumph amp have been done he'll be ready for gigging too.
