    Just got the head from big brown, put it in the rack and connected it to my Avatar 210 and 112 as such:

    Head - Speakon - 210 - 1/4 10 guage - 112

    I then tried just connecting one cab a time via speakon

    This thing is not loud at all. My Hartke blows it away. I had the volume to 8 and not much at all. I called Kustom and was told at 5pm that the tech had left for the day and no one could help me till tomorrow. :help:
     
  2. This was my complaint when I tried one in a shop.

    First off, run the EQ flat and mid way up. Crank the gain to just where it clips on low notes and back it off a hair. Then bring your master up. This will help a lot. The head REALLY comes alive under a 4 ohm load...

    I have 2 4 ohm cabs, so I am running at 2ohms. It is still not as loud as my Hartke! :confused:

    How do you have your switches set? (especially the active/passive one). I play an active bass, but use the passive setting. Then I set pre amp gain like Quad just explained. I start clipping around 12:00 or so...btw, my parametric eq is: bass around 9:00, mids around 1:00, and treble around 11:00. I run a 2 ohm load and my Master volume never gets past 1:00 'cause it's too loud

    Ok, I think I may have panicked. :eek: I EQ'd like Quad said and it came to life. Much louder. I am going to have to tweak it a bit more before I make any final judgements.

    Ok, just called Kustom Cust Service. The guy said that running my 2 4ohm caba in series might result in an 8ohm load. :eyebrow: :rollno:
    So I am waiting for a tech to call me back

    Off the subject a bit but Ghost how do you like the 1x12 with 2x10? I have 2 2x10 kappa pro's but Im thinking about getting the 1x12 w/2x10 and ditching one of the 2x10 unless I need it for a larger show. I will also be getting the 1x12 in 4ohm and using it solo for a side funk project and also to save a little carring weight then the 2x10.

    Only if you were using a custom "in series" (verses standard parallel) cable. If you are using two cables or daisy chaining the cabsm you are in parallel mode which means 2 ohms (with 2 - 4 ohms cabs). I have a series cable that I ordered special from Pro Cables and Sound that I use when running two - 4 ohm cabs to my Peavey Classic 400 head (only does 4 and 8 ohms). I doubt you have a series cable unless you ordered one from a custom cable place, plus it's a "Y" cable with one connector one the head and one for each cab.

    If you are still having volume issues, I suspect something is wrong as my GB1200 would crush with a 4 ohm load (runing a 1x12 and 2x10). Unless your cabs are REALLY inefficient... Dunno.... :confused:

    Just got off the phone with the tech. Looks like the sweet spot for power is with the master around 11 o'clock and up. There is a MASSIVE increase of volume there. So maybe it is a case of my expectations being that this amp should crush at 7 o'clock (1). :meh:

    Knob positions mean little by themselves anyway. The game is about gettting the best out of the gain structure, matching well to input source, etc. I suspect a number of "amp" manufacturers - especially ones that also build guitar rigs - have skewed their circuits so that their gear makes full output with low knob settings. A sucker trap. Because the power section is only going to make so much power anyway. The important thing is that knobs allow a lot of adjustment sensitivity, especially for input gain and in the case of overdriving at the preamp if the design is meant to do that.

    Correct...

    as I've said, I usually keep mine around 12:00 - 1:00 and have never had any problems with volume :D
