How to set my amp EQ when using a pre-amp?

[BigBobbyBass]

I'd start at a flat setting, then use the amp controls to eq for the room (and cabinet mix, if you're swapping around), and the preamp controls to eq for the basses/performance.

i would think of the pre-eq as working for the basses ... and the amp eq for controlling the sound of the speaker and room ... you can try to find " flat " ... even running a pink noise generator and a calibrated mic/ frequency analyzer ... you might find ' flat ' for that given moment ... but i think/found ' flat ' to be a moving target .. !! with many always changing variables ...

take your best guess ... adjust to taste ... play

none of this makes any sense to me. Both eq's are going to effect "the room/cabinet mix" and "basses/performance"..

My understanding of the bassbone series is that they are designed to plug into the front instrument input of your bass amp. They are not designed to drive a power amp, the gain is not that high, designed so you will not overdrive the amp. All of the pics in the radial literature show them going into the front instrument input. You are not going to hurt anything by going fx return or power amp in but that is not the intended design for the bassbones.

I use caution on my bassbone od to make sure I am not over eq'ing and tend to use the bassbone eq more and my ToneHammer500 very little. I start with all eq at noon, try the HPF to see if I want to use that and then adjust my bassbone eq and then a small tweak on TH if needed. Seems to work well.

1) Power-amp in

I forgot that the PF-500 had a dedicated power-amp in. This is exactly what it is for (access to the power amp). The effects return will probably tie into the same place in the circuit, but also offers a level control (the fx mix on the front). Since the pre-amp you are using has a level control on its own, you can just use it.

True, and there nothing wrong in twiddling two sets of knobs when setting up at a gig, but the two-stage approach means you can 'bake-in' your basic tones using the preamps, then if the room or stage is a bit boomy or a mid-sucker you can compensate on the amp EQ without touching your basic setup. In the same way as a decent house PA will have a master graphic EQ that is 'set-and-forget' - it compensates the entire system to the room, usually through spectrum analysis, such that 'flat' on any one channel is actually flat. Except here we are working in reverse - we set and forget our tone then compensate for the room to ensure it is heard the way we intend it to be..

My Bassbone v1 is a unity gain device. Not sure about the OD. If like mine, it is unity gain, then you'll want to plug into the instrument input as there will not be output enough to drive the power amp... Th OP probably has this sorted by now I would guess.
