nottswarwick Posted November 4, 2021 Share Posted November 4, 2021 Hi In my FRFR project, for a rig that will do bass and guitar, a thought has occurred: I could use a Barefaced Big Baby2, and my Little Marcus 1000 for both duties, but only if one thing is clear: So does anyone know if the effect return on this head is post preamp and all EQ - ie direct into the Power Amp. If it goes straight to the Power Amp, it would work. Manual is no help. I may email Markbass, but thought I would ask here first.

la bam Posted November 4, 2021 Share Posted November 4, 2021 I had a markbass evo I- I think you couldnt disable the preamp / eq via send/return etc so wasnt useful for that project. Quote Link to comment Share on other sites More sharing options...

BillyBass Posted November 4, 2021 Share Posted November 4, 2021 I have the limited edition 'iron man' Marcus Miller 500W head. Unfortunately, going into the effects return does not circumvent the EQ on this, so I doubt yours would either. Quote Link to comment Share on other sites More sharing options...

So, it is still for sale. Quote Link to comment Share on other sites More sharing options...
Dood Posted November 4, 2021 Share Posted November 4, 2021 The F1 definitely had an effects loop before the EQ - however, given that it's an active EQ, just set all the controls to flat and you'll notice minimal difference. 2 Quote Link to comment Share on other sites More sharing options...

nottswarwick Posted November 4, 2021 Author Share Posted November 4, 2021 thanks chaps. got to be worth a try I guess. A super midget would be ok for me actually. Food for thought. FRFR for guitar with a pre of my choice, and still a proper bass amp for bass duties. Quote Link to comment Share on other sites More sharing options...
songofthewind Posted November 4, 2021 Share Posted November 4, 2021 In the Combo Head there is a jumper inside the amp which routes the fx loop signal pre or post EQ. I wonder if this applies to other MarkBass amps. There is an article somewhere on the web, with pix, of how to do this. I have swapped back and forth many times. It is super easy to do. Personally I didn’t think it made much difference. 1 Quote Link to comment Share on other sites More sharing options...
nottswarwick Posted November 4, 2021 Author Share Posted November 4, 2021 (edited) Well, I have just tried this: tech21 guitar fly rig v2, into both the bass input and the effect loop return obv not at the same time. Used the DI output into my studio desk and monitors, as I don’t have a cab at the moment, but the test remains valid using the DI output of the Marcus Head. I find that the effect return is indeed post EQ but that is fine, sounds flat, when set as such. However, there is clearly some sort of other pre amp shaping immediately after the instrument input on the head, as plugging in here does not sound good for guitar. So I guess this is the input gain stage? Edited November 4, 2021 by nottswarwick Quote Link to comment Share on other sites More sharing options...

Personally I didn’t think it made much difference. I think from memory the jumper switched the effects loop from parallel to series, not pre- post EQ. I'm prepared to be corrected on that mind. Would certainly support why you wouldn't have noticed too much difference. Quote Link to comment Share on other sites More sharing options...

However there is a huge difference between using the instrument input vs the effect return. The instrument input must have another preamp inside, before the main eq you can change, while the effects return is nice and clean. Quote Link to comment Share on other sites More sharing options...
pete.young Posted November 4, 2021 Share Posted November 4, 2021 THe LMII which I think was the original combo head had two jumpers, one for DI pre/post and the other for loop series / parallel. Never owned an LMIII, but I think that had an external pre/post DI switch and a blend control. Quote Link to comment Share on other sites More sharing options...

Thanks for that, Dood. 1 Quote Link to comment Share on other sites More sharing options...
