I recently upgraded from some lower end preamps and added the ISA 428 MKII. The sonic quality of the 428 is amazing. The unit has tons of clean gain. I don't experience the harshness or thin caracter that seemed to be the norm with my previous units. I absolutely love the sound when plugging in direct. On Bass the unit has a wonderful transparent and full frequency response with a nice touch of mid range warmth and definition. I also love it on drums and acoustic. I love using the ISA for summing. It sounds fantastic and with the inserts on each channel I can still use my outboard gear while utilizing the ISA's digital converters which sound way better than the stock converters on my interface. The only drawback for this unit is I wish Focusrite would have kept the Vu metering like on older 428 models but overall for the price you'll be hard pressed to find another 4 channel pre with this many features that sounds this good.

great product! this was my second high end mic pre after an ssl alpha vhd. both of the products i love, as much as i am in love with my 2 chameleon labs 7622's. this is a great 4 channel solution for anyone that needs a tremendous amount of versatility to their setup. the variable impedance is a miraculous addition. it made an sm58 sound great! the unit is well laid out for all of the options each channel has and although the meters are a bit slow, are fairly accurate. not as aggressive as my ssl and not as punchy as my CL's, the isa428 is middle ground with it. a slightly colored sound with a warm touch, the tone is solid with a full midrange. this is my first choice for cymbals. it has become my go to pre for overheads and close mic'd ride and hi hats. i use moderately priced condensers for this application: adk sl pair and rode nt5 pair. both are fairly bright mics and the isa428 warmed them up and made them sound incredibly sweet. a high class pre.
