stomp box crossover?

[SteveMcB]

There are plenty of stompboxes with crossovers in them (see behringer bass chorus, most of the ashdown fx range and many others) but AFAIK, the Peavey BAC-2 Biamp bass chorus is the only one with seperate outs for high and low frequencies. It's not in production any more, but turns up on ebay and TB classifieds occasionally. It's a great pedal and is the heart of my biamping setup. I think it's pretty much the only game in town. All other crossovers I could find (including the Rolls) are designed for line level inputs/outputs.

Mark, a crossover allows you to split your high-end from your low end. This is important in some rigs that send all the lows into a 115, 118, or some other "sub" cabinet, but sends the rest into a 410 or something.

This has also been used in compression (Trace Elliot, Rane DC24, etc.) and some choruses. I believe there are even a couple distortion units (Ashdown, to name one) with something of a crossover in them.

thanks for the explanation guys.

im still sticking to the Mono world. they know me there.

+1. i think. eventually i am going to get another GK amp and then i might start running a Crossover.

This is what I do for crossovering (yes thats a word! )
pedals -> splitter -> EQ bass cut -> to guitar amp
-> EQ high cut -> to bass amp

I use a Behringer 30 band dual channel ultra totally awesome rack EQ

This is basically a crossover but without the word crossover on the top right?

Yeah, that's pretty much a jerry-rigged crossover.

A true crossover would separate the low and high frequencies completely. Using an EQ to do it dials down the highs (or lows), but it can never completely get rid of them. It just makes those cut frequencies really quiet.

It doesn't exist.
I thought about it many times.
A looper with a built-in crossover could do wonders.

 

[SteveMcB]

It does too exist! It's the Peavey BAC-2 Biamp bass chorus. It's a crossover with seperate outs for the highs and lows. Forget about the chorus if you want (but it's a nice chorus), it's a crossover pedal.

Of course it's not being made any more, but it's not that rare and is pretty rugged (metal casing etc). And it really, really, really needs an adapter as it eats 9volts big time!

Well yeah the old BAC-2 has been quoted several times in the thread already. It's still a compromise.

Half-a-crossover ISN'T a crossover - by definition.

My thought on the matter is that the PA system kind of crossover is NOT the ideal thing for what most of us would want to do!

The high-pass/low-pass filters in PA crossovers are made with steep slopes, to try'n keep one speaker's stuff OUT of the other - ideally, an infinite-slope 'splice' would be desired. But for using highs/lows processing like we are, I'd think that we'd like a nice, shallow slope - a gradual 'handing-over' from one side to the other! Heck - probably a basic 6dB/oct simple, PASSIVE RC circuit would be more-ideal! Ganged-pots would leave it sweep-adjustable too!

the Xotic X-blender has a cross-over built into the loop section. I use it run all my highs through my fx chain in the loop, and leave my bottom end unaffected and clean.

 

[SteveMcB]

How the BAC-2 a compromise as a crossover? It's a crossover in a stomp box... It's pretty much just what the original poster was asking about

And Joe P, as I understand it, the other boxes I quoted have complete crossovers, they just have a mixer too which blends the split signals back together... However I was just pointing that out to say that while there are lots of boxes with crossovers in them, AFAIK there was only one (BAC-2) that actually functioned as a crossover.

It's a compromise because you can't even adjust the crossover frequency of fully turn off the chorus.

Xotic isn't aware of this function.

Xotic didn't even build that function in.

True, you can't adjust the crossover frequency... Not true that you can't turn the chorus off. The chorus is footswitchable (effect is on the high band only) on vs off. If you want a fully featured crossover the BAC-2 is certainly a compromise compared to a nice rack crossover. However, a rack crossover is also a compromise, 'cause the original poster wanted a pedal, not a rack unit

In terms of commercially built pedals, AFAIK, the BAC-2 is the only game in town, fully featured or not. It does the very job that the poster was asking about for me. I own it and can (and do) therefore give a well-qualified recommendation.

Treble / Bass controls treble and bass of the effect signal. This two band EQ is activated when the blend switch is turned on.

Ok, ok, so it's just an EQ for the fx loop..

next time i'll put down the bong and back away from the computer.

 

[brisonic]

I recall that one of the boss multi effect bass stompers has a crossover.
