Double Bass Headway EDB1 preamp

hi guys this sounds like what i am looking for i am currently using a realist into a borrowed Baggs venue DI into iamp and NL210 and getting a good workable tone. But the extra features of a second chanel and a HPF (the venue has notch only) should be good.

The realist into the baggs is pretty hot i have the gain set on the baggs and about 9 oclock. Anyone have any idea how it would compare to the Baggs?

Bassplayer48,
You most likely will have have the same problem with the Realist into the Headway, especially if you mix it with a condenser microphone. The simplest solution is a attenuated cable that David Gage sells for the Realist/Headway combination. The high pass filter is actually the combination of switch that fixes the HPF at 41 Hz 9(for Bass), 85Hz (for Guitar), or 192Hz (for Violin) and the Low and Low Mid EQ controls. Only the two lower settings are useful for the Double Bass.

Some Pickups like the Realist or the Bassbalsereit might be far too hot for the input of the EDB1. But this can be changed permanently with some soldering work. I’ve just got a EDB1 modified for hotter pickups, and it just works fine.

Jonas,
I just sent you a P.M. regarding the Headway EDB-1 modification. Could you kindly take a look at it and let me know what you think?

one thing guys when i plug a preamp into my iamp800 should i be plugging it into the active input? i have been plugging it into the passive input. Since the baggs i have been using has a 10meg ohm input i'm assuming that the lower gain of the active input should mean i can get more gain on the preamp?

Ok so i just tried the bass into the baggs pre into the return of the fx and it works fine and bypasses the iamps pre, but pcikup signal is still very hot as before, as mentioned the padded cable would be a good fix. However i was thinking if i plug the bags through the fx loop and plug the bass directly into the amps passive input will that get rid of any overloading? And for doubling on electric i guess if i just turn down the fx gain that will cancel out the baggs pre for electric?

I realise that won't bypass the iamps pre for the DB but that might be ok.

You can certainly do that however it's diminishing the value of the baggs usefulness. The biggest value of outboard preamps is how they load your pickup. As soon as you aren't plugging into it they become a line level EQ. If you like the sound of that particular EQ that's one thing but then you have added an additional series of gain stages that may or may not be of value to your sound, in addition may add unwanted noise.

The iamp has a very powerful EQ already. You may like it's sound, you may not, but you have to consider the purpose of all those knobs....do you actually need them? That's a lot of gain stages and filters to pass through. If you aren't using them or they aren't adding much to your sound that is important to you I'd leave out what I don't need.

Keep it simple is my thinking. Less stuff means more durability, better tone, and easier diagnosis when things go wrong.

If the pickup doesn't work in the front of the unit you are using, modify the unit so it does or use some other combination, different pickup, different preamp, or different rig.

thats a great point, the other option i have is to get an fdeck hpf and plug through that and use the amps EQ the only thing is for doubling i have to tweak the eq back and forth although it sure is the easiest and cheapest option.

I know Francis does not ship outside the US but i have friend coming to NY later this week so its doable.

BP48,
F Deck's HPF/Pre was designed to go in front of the EQ on your amplifier and add features that the iAMP doesn't have. So what you get is a High Pass Filter, Phase Reverse Switch, and a 10 megohm input. Version 2 has a couple of added features a Volume Control and a battery indicator. If you really want to solve the EQ problem a Dual Channel amplifier is calling your name.
