    Any GK users here tell me what rack/size I should buy for my new amp (Also have a BBE and Conditioner)?

    Never owned a rack...combo amps until now.

    Thanks.

    A standard rack space (also known as 1U) is 1.75 in. Your GK head would need two spaces.

    Assuming that both BBE and Conditioner are 1U each, you'd need at least 4 spaces (4U) total (2+1+1).

    Don't buy a rack advertised as an "effects rack" They're usually shallower and your amp would stick out the back.

    You may want a space between your amp and the stuff above..and you may want to add a compressor or a wireless or something in the future. I'd recommend a 6U rack...buy it once and you're done.

    I have a bunch of SKBs. Found most of them at Music Go Round stores for pretty good prices.

    Make sure to leave a space above your GK, because that's where the exhaust fan ... exhausts.

    Hmmm.. The math isnt working dimensionally. SKB cases(standard not effects) are 18 inches deep and the GK 400 RB IV is only 8 inches deep. Is the GK a "shallow" amp? Maybe the Effects racks (stated as 12 inches deep) would work.

    I get the part about spacing, vertically, that measures up.

    Yeah, it's pretty shallow. You might be fine with a small rack, but if you ever plan on adding anything extra, you might get a big one. I added a poweramp, for example.

    Also, account for any jacks and the opening in the back. If it is a full-size back opening, you'll be fine, but sometimes they have these little "window" openings that are smaller, and that could complicate your cabling.

    O-I-C. Need cable space behind.

    So I guess I would run the bass cable into the BBE input (rear of unit) the cable from ther to the front GK 400 input, no that doesnt sound right. Why dont these fricken mauals show how to chain the equipment? Such sophisticated processing and the manual has nothing on what plugs where....time to experiment.

    Guitar player I knew ran a BBE through his effects loop. You may find that that would be the best option: bass to GK in, GK FX send to BBE in, BBE out to GKFX return.

    You may also find that with higher power amps, a BBE starts to degrade the tone more than it makes it better. At low volume, they sound great, but at real volume (which the 400 can definately put out), the results tend to be mixed.

    Hope this all helps.
