    quick back story - I used to play upright to slab pretty much 80/20 (high school - college) then with it switched to about 1/99 sad times for my 1890 czech flat back sad times indeed I can hear it whimpering in the corner for some love...

    back in the day I was pretty good with a simple rig

    underwood + GK400RB + SWR Golliath JR

    now I have been dusting off the upright webs and need to look at what I have available to amp my bass.

    my inventory:

    slab rig:
    Aguilar DB750
    GS112 x 2

    possible upright items:
    GK400RB (late 80s model, tried true)
    Underwood
    Realist
    Shure SM57

    misc. items
    Behringer XENYX 502 - mini mixer
    Aguilar DB924 - outboard pre

    as with many others... times are tight and I really can't invest a good amount for any big items but I'm thinking I can use 1 of the GS112s w/ the GK400RB and... I dig both pickups but I feel/know I'll need a more specific upright pre given my this inventory will I be good w/ just the TB'er built HPF pre or will I benefit to save up for a more robust tool like plat pro? I'm open to other possible suggestions. Thanks.

    I have not used the Fishman Plat Pre, but I do have the HPF-Pre. Since both your amps have EQ onboard, I would say maybe try the HPF-Pre first. Gives you a 10 Mohm impedance input, a high pass filter (duh), and phase reversal.

    Some combination of all that stuff you have should at least bring a grin to you and your flatback. :) Actually I'd be curious to hear how the Aguilar 750 sounds with upright. :cool:

    P.S. Do both the 750 and the GK have a DI output for the PA? Plat Pre does, HPF-Pre does not. Might be another consideration.

    no DI on the GK... I do have an old IMP DI that I can use though

    I haven't really thought about trying upright with the DB750 I guess it couldn't hurt to give it a go.

    I've never used a Plat Pro Pre, but in my opinion you'd be fine with the HP-Pre, that's what I use. The GK400RB doesn't have a DI?? Huh, my 800RB had one, I figured the 400RB would do, I understand they're very similar.

    Not a big problem though, every sound guy I've run across has a DI box for the bass, and they're pleased when the amp has a DI instead.
     
  5. the fishman pro plat. has been great straight to the pa. i dont even take my amp to gigs anymore. has a good eq, good di, high pass filter, phase switch, and a compressor.
    sound guys have had no problem with the signal i give them to get a really nice sound.

    so I ordered a HPF pre so my test runs included

    me bass > realist a/b'ed with a underwood > GK400RB > GS112

    great googley mooogley it was BOOMy so I start in with the pre that helps a bit then the EQ and for the love pete the boom held on with it's teeth showing...

    I don't blame the pre and I don't blame the head... so there it is the big arse bass GS112... i love this for slab but I need to find something for upright....

    given my current setup... any recommendations, this is for a speaker btw?

    thanks

    I don't think the GS112 is the problem (aguilar right?) I have one and I think it sounds good. I've used it as both an ext cab with my GK MB150S and with my AI. Part of the reason I don't use it is the size and it is 8ohms. I bought an EA that is 4 ohms and performs better in close spaces.

    I'd try to dial out the boominess with a HPF. I have the Fishman and won't leave home without it.

    I've had a Fishman Pro eq for many years. It is the Plat's lower cost brother and doesn't have a lot of its features, incl the compressor and DI, but it's got phase reversal and four-way eq and it has served me well. I recently got a Plat and used it for a few gigs with, variously, an iAmp and Clarus going into a Wizzy10 on top of a Wizzy12. I've been uneasy about the sound I've been getting and yesterday during the first interval I put the Pro back on. Result, a tightness in the attack that I seemed to have missed with the Plat. Strange.

    I don't hear the Pro mentioned much. Anyone had any experiences?

    So you turned the dial on the HPF-Pre gradually up from the lowest setting of 35 Hz and it still sounded boomy? Man, that's different. Hm, dunno.

    I see you mentioned a Realist, but did that happen with the Underwood too?

    Be glad to talk about speaker recommendations too, but something just seems amiss. Then again it could be me. :rolleyes:
