Love hearing this stuff. . I was the 1st guy I know who heard of Engl back in the 80's. They had the digital amp that remembered a few presets, and then the Straight 100, the 620 /520 preamps,etc. You could find them used in Boston , or at the original Daddy's stores ,but very rare. . The Boston band SHOCKRA had this guitarist who used the digital combo and he got some of the best tones ever (early 90's) . . . I still have the 520 preamp , Engl Screamer combo , and a 4x12 from the early 90's , a 100 watt stereo power amp with boosts, and my favorite is this 2x35 watt rackmountable stereo el84 amp. . It's 3 channels , 2 amps in 1 and rare as hell! I love it. Then Engl took a huge hiatus , and then in the past 10 years or so started cranking out the amps. .. . I haven't been lucky enough to try any of the modern gear they make ,but have surely heard lots of views on them , and I'm glad some of you guys are digging them . Eric
