Bass preamp as effect pedal?
I've never used effects other than compressor so I finally made the decision to get some dirt :)
I like the sound/features of the EBS microdrive but it says it's a preamp unit. So the question is can a preamp pedal be used as a two channel effect and how will it sound if I just connect it between the bass and the input of the amp? I couldn't find any information about this so any info would be appreciated.
If I get a preamp should I only connect it to the return and use it instaead of the amp's preamp?
Pre-amp, to me, means anything put before the amplification stage of an amp. So for instance, the Mesa M9 I use has a built in tube preamp, which I leave flat. But I do use an eq/pre-amp pedal (Submarine Designer) to shape my basic tone before it reaches the amp's pre-amp. I also use a B3K to add grit and grind to my signal before it reaches the Submarine. So it too is a pre-amp.
Some effects (and anything save your bass and amplifier should be considered effects) sound better in the amp's send/return loop, others sound better between the bass and amp. I think the Multidrive would sound best before your amp, but that is just a guess based on it's design feature and my experience with drive effects.
You'll read this a lot here but experiment to see where your effects sound best.
Off the top of my head, yeah, put the Multidrive between your bass and amp and use it as an on/off drive effect.
first of all, from what I understand you have mixed a couple of names here. I believe that you are talking about the EBS microbass not the multidrive. The Multidrive is a distortion pedal effect, whereas the microbass is a 2 channer preamp with a distortion channel.
Now that this is out of the way, of course you can use it in front of your amp. You see this pedals, and also other similar preamps in pedal format have an instrument level output that can be used with an amp. Moreover they have a line level output (the one with the three pins, just like microphones do) that can be used so that you can go directly to a mixing board or a powe amp.
You can still go through the effects loop only. Some people do that because in most amps it allows them to bypass the preamp of the amplifier, so that they can keep the signal from their effect/preamp pedal as pure as possible.
I use a similar pedal, but I don't go through the effects loop. In live situations, I send the line level signal to the mixer and the instrument level to my amp. This way the soundguy gets "my sound" and can adapt it to the venue, I use my amp onstage as a monitor and the all eq changes that I might have to do in order to hear myself well on stage will not affect the signal the soundguy gets. Moreover in the case that something goes wrong with the amp, the preamp pedal, will still send a signal to the soundguy so I will still come through the venues speaker system.
I hope this helps the microbass is a wonderful preamp.
And on the other hand I don't want to bypass the amp's preamp, because it has a built-in compressor which I still want in my chain.
I have two rigs:
One is an Eden rig with a Navigator preamp going into a solid state power amp. I would not use a preamp pedal in front of the Navigator. It is much more versatile than any preamp pedal.
The second rig does not have a preamp. I go straight from my pedal board to a rack compressor into a solid state power amp. In my parallel effects chain I have an Eden WTDI pedal, which is a much smaller and very stripped down version of an Eden preamp section. (I blend it with various effects.)
For most purposes, I would not feed my bass into a preamp pedal and then into a rack preamp. It seems redundant to me, and I doubt you can simultaneously stomp on switches to bypass your rack preamp and go with just your preamp pedal.
However, if you want to do something drastic, like stomping on a box that guts mids, or boosts bass, or something like that, a preamp pedal could be useful, but I would go with a nice EQ pedal instead. It would work fine. Just remember that your final, rack preamp gets the "final say" in your tone/EQ settings.
To me it sounds like you would be fine without a preamp pedal. But, like I said, if you want a drastic EQ change, just buy an EQ pedal. That's my only advice.
Hey E.J., so you run a DI out of the pedal preamp you're using to the FOH and then plug your board into the amps pre correct? Am I reading this correctly? So it's like you have a monitor on stage (your amp) for you and the FOH is just picking up your board and not your amp? Or is this incorrect.
I've used effect pedals as preamps in the past (clean buffers can sound fantastic) so you should be fine.
you could do any of those things. If you want a pedalboard swiss army knife then the microbassII is an amazing product. I hope you like it.
You can use the Microbass 2 two ways.
1) As a preamp to drive a power amp. This is what it was designed do. Think a rack pre except on the floor. It's how I use it. I drove a Crown amp for a while but know I use Bag End powered cabs.
2) As an effect. In this case it would act as a EQ/DI/Drive pedal. Like a really nice Sansamp Bass Driver, except it can not be turned off.
The only thing you need to watch out for is gain stage stacking. Make sure you are setting the output so that it's not BOOSTING your signal. If you do this it's possible to cause the preamp in you amp to overdrive and distort. Turn it all the way up and you could damage the input of the amp.
Gain stage stacking can happen with any effect with an output volume knob. Drives and Compressors. Generally you want to set each pedal so that when it's on you don't get a volume jump. This is called "unity gain", the output volume is the same as the inputs.
There are tonal reasons to use one drive pedal to hit a second drive hard. Guitar players do this pretty often, especially blues players. SRV did this a lot.
Keep in mind that each gain stage has a hiss. If you feed one gain into another gain stage, the second will amplify everything it hears including the hiss and it adds it's own.
To the compressor placement question. I put mine before the Microbass and any other amp for that matter. The loop in the Microbass is AFTER the EQ section. Putting it in the loop can make the compressor hard to set, especially if you use a lot of low end boost on the EQ. My comp is pretty early in my signal chain, after envelope and octaves but before the drive.
On EBS's demo boards all effects are before the Microbass. Nothing is in the loop.
The only thing to watch out for on the EBS is that it's possible to push it's input into clip, i.e. distortion. Since there's not clip LED you really have to pay attention. I've mentioned this to EBS a couple of times through email and at NAMM. It's the only thing they really need to add.
I set it in A+B mode and scoop the mids. I don't use the drive at all.
I use the DI all the time with speaker sim on. It's really dialed in.
I have the tube sim on also. I used to have a Demeter Pre HPB1. I A/B tested with the Microbass with tube sim on... well... I said I used to have a Demeter.
That thing is great. You're gonna love it. I tried everything I can find that is like it, but haven't found one better.
Thanks for the replies!
I got it finally and tested last week. This unit is great!
I use a warwick corvette $$ through a warwick BC300 combo and the sound is really good no matter how I use the unit (as a preamp in the return or effect pedal etc.). Still have to try it in the PA, but I'll definetely do that the next gig.
Few thoughts on the unit:
I think channel B is slightly mid scooped.
I really like the tube sim + bright switch and if I scoop the mids (A+B mode) then I get a really nice slap tone.
What I noticed is that it is not easy to balance the two channels if you want to have one clean and one with OD, but fiddling with the boost on channel A does the trick.
