I joined a band recently (first time in over 20 years). Everything is going well, but I am not satisfied with my tone. I am using a Hughes & Kettner Duotone into a Mesa 4x12 slant rectifier cabinet. We practice at fairly conservative volume levels. My issue is that my tone sounds really midrangey. I can't seem to get any low end unless I turn up the amp a bit more, but then I am too loud. I love the amp; I've used it for other jams (at higher volume) and it sounds great; but at lower levels with my band, I can't get any thump out of it. Our other guitarist uses a first generation Dual Rectifier, with two (!) 4x12 cabinets, and he has plenty of low end. I am friends with Tim O'Brien from O'Brien Amplifiers, who can put a pentode/triode switch on it to cut my power. Will this do what I need? Any other suggestions? No one in the band has complained, but I am wanting a fuller sound. I have a Roccaforte Jenelle and a Heritage Colonial amp as well, but I really don't want to gig with those. I picked up the H&K for a sweet sweet price, and love it in all respects, except for the purpose I bought it for - using it with my band. Not that it matters, but we play variety rock/hard rock from the 70s through modern day (AC/DC & Kiss to Ratt to Seether & Theory of a Deadman). Thanks for any suggestions. - E.
