Re: power attenuator
I recentley bought a Weber Lite Mass 100 and I think it's fantastic!
It's got 2 dials for attenuation. One dial is for the Lows/Mids and the other dial is for the Mids/Highs. This works really well with my DSL 50. Why anyone would build that much treble into an amp is beyond me. I tried Beam Blockers (which did help) and even had my EQ pedal going into the loop to calm the high end down but I did'nt care for the results.
Now with the Mass Lite I keep the dial for the Lows/Mids at about a 12:00 position and keep the dial for the Mids/Highs at about a 7:00 position and all of that nasty, ear-grinding ice-pick treble is smoothed out. Now I can actually use the Mid, Treble and Presence controls on my amp to a degree that was'nt possible before and it's made a HUGE differance in the way my amp sounds.
I would highly recommend looking into one of these units not only for the attenuation, but also for those whos amps have an excess of treble.
