dual mono rig?

[jeffgnr90]

Hi guys I've been reading all the threads on biamping and dual mono and such, and I'm looking to do what I think is dual mono. I I have 2 bass cabs and a guitar combo amp that I want to add. My hopes were to get a very prog. type sound with my clean going to my bass cabs and adding some dirt from the guitar amp. I think that Chris Squire and Geddy Lee at some point in their lives have done something very similar from my readings. I assume I'd need a ric-o-sound or something similar to make this possible. The bass cabs are full range also. Any insight to this? I was hoping I would find somebody who has tried the same thing I am looking to test out but to no avail, maybe for good reason,

I've done this. Plug into a DI, like a SANSAmp BDDI, the go out of DI into one amp, out of DI into another amp.

When I play outdoors I use this setup.

I actually own a Sansamp BDDI deluxe which i use frequently. How would I do this the if that pedal has just one output? Normall it would be my bass into the main input, then output into my head. Would I need to use the parallel out in order to go into my guitar combo amp? Or vice versa? And would that eliminate the need of something like the ric-o-sound, since the sansamp is doing so?

I used to do this. A/B/Y dual amp setups offer some fun experimentation and such. They also offer ground loops, among other problems. There are ways of with dealing with ground loop hum, and other issues though. I liked the sounds I was getting quite a bit. It was put together for a very specific project that didn't last very long. Since then I have worked with effects but kept things to one amp setup. The only thing that would make me jump to dual mono rigs is getting my analog synth its own stage rig. anyway, here is how it worked:

1. bass --> boss tu-2 tuner to split the signal into a and b(I don't recommend this at all, these boxes don't like to be used for this function, and it only allowed for a and a/b function):

a. effects1 --> tube pre/ss power/410 cab bass rig
b. effects 2 --> peavey bandit 112 overdrive channel with bass eq cut all the way and dirt to taste

these blended together fantastically--had my drummer not moved to australia I would've fleshed out the rig and worked out the kinks. the midrange-only distortion from the solid state peavey guitar amp blended so beautifully with my octave pedal going into my 410 rig. let me dig this article up though about a/b/y boxes... from fulltone pedals:

WHEW! Now i'm getting pumped. I want to do this just for the sake of experimentation, cause who know, this may just kick my A$$! So am I safe in assuming that an A/B pedal would function the same as a ric-o-sound? lol I have the ric-o-sound stuck in my head like it's a necessary component in doing this, maybe I'm wrong in that assumption. But that Is basically what I would have done with the guitar cab, turn down the bass and throw in some dirt. Just so you guys know what I'm dealling with, it would be an Acoustic b600h into 2 svt-210s and a 212 120w crate combo amp. Thanks for these responses, I love hearing other people's experiences with similar setups. That link was also pretty informative also. I'm aware of the possible phase cancellations and other nuances as a result of doing this except for the ground loop problem.

forget the ric-o-sound, that's not needed at all.

run a regular bass rig, then send the "preamp out" or "effects send" from the back of the bass amp into the front of the guitar amp, into the second, lower-gain input jack if it has one.

back the bass knob down on the guitar amp (to save the guitar speakers) then bring up the crunchy guitar amp sound to blend with the clean bass amp sound. you won't need much.

Ima try that, thanks for the pointer!

I would really recommend something like the Radial Big Shot ABY or similar. There are a few reasons. You can go from one sound to the other or both on the fly. You have a ground lift in case you have a ground hum problem but most importantly you have a phase reversal switch. Many times two amps will not be in phase with one another which means your sound will get smaller which is probably not the direction you wish to go.

thanks for the recommendation! Seem cheap enough and easy to use, I'll have to give it a shot!

I have a set up which is based on the theme your post mentioned, of course there are many variations to setting up a bi-amp or dual mono rig so you'll have to experiment a little...I basically run a 4x12 with a dedicated amp and set it up so it sounds well defined yet also has a chunky yet smooth overdrive, the direct out of this same amp (uneffected clean signal) feeds a simple rack mount eq used to emphasize the ultra lows, this then feeds a power amp which powers a 2x18 cab. In most dual mono or bi-amp rigs one of the nice features is the ability to balance the cabinets levels so they mix together in a manner you prefer plus each cab doesn't have to be pushed as hard since it's dedicated to a given frequency group, of course lugging around a bi-amped rig is a bit more difficult then carting around a simple 2x10 or 4x10, nonetheless in my opinion I love the way a bass sounds through a 4x12 while being backed up by the concussive pressure a dedicated sub brings. Anyway I hope you find a set up that works for you and have a great day.

Is the 412 a guitar cab or a bass cab? And are you using a cross fader at all? I like the sound i got when i tested this out, minus the white noise. But the only way this will pass is if it sits well in a band setting. Obviously the aby pedal will more then likely cure the white noise which was the only negative. On the bass amp i rolled off some of the 800hz/2k to give the guitar combo some room mix wise. I assume this will prove beneficial, more notably in a live/band setting.

It's actually an upright 4x12 pa cab from a company called Soundcity, it's been retrofitted with 4 high powered and sensitive guitar type speakers (Eminence Swamp Thangs), this is powered by a Carvin BX-1200 which is more power then needed since the 4 speakers have a combined power handling of only 600 watts however due to their high sensitivity of almost 103 db @ 1w/1m (with all 4 speakers it's around 105-106 db) I don't really have to use more then 2-300 watts to get incredibly loud mid bass/mids, of course since it's an 'upright' the top speaker is right near ear height which helps with perceived volume. As far as a cross fader I don't use one since level adjustments can be made from either the Carvin or power amp however the notion of a quick change cross fader sounds like a great idea (much quicker for balance adjustments), by the way -do you think the white noise you were getting had something to do with the guitar amp? Anyway hope it works out and have a great day.
