How to use 2 bass amps at the same time?

[Gerardo Velasco]

Hello fellow bassists!

I just ñurchased a Accugroove Whappo, the Powered version. And i have a Hartke LH1000. I would like to run them both at the same time. I was looking into the Twch 21 Geddy Lee 2112. So i can use one XLR into the Whappo and a Line out into the Lh1000. Would that be possible?

Cheers!

The easiest way to connect the two is to use an XLR cable from the LH1000 Direct Out to the El Whappo input. The LH1000 essentially becomes a 32 pound preamp.

If you use the 2112 the LH1000 would need its own cabinet. Your description of the signal path is correct for either the rack mount or pedal version of the 2112.

Sorry, forgot to mention that the LH1000 has a 4x10 and a 1x15 Hydrive cabs.

Yeah, that sounds good! Just making the LH1000 a direct out to the powered Whappo!

The DI Output is pre-EQ so you won’t have any control over it’s tone.

I use my Sansamp's parallel out. It's first in the signal chain so the output is dry. It goes to an amp which feeds a MB 102. The effect chain carries the other signal to a MB 121 combo.

This has sparked my curiosity. You're expanding your 1000 watt full stack with a massive active cabinet called El Whappo.
Do you need another cabinet pointing in a different direction or is your Hartke stack not loud enough?

The effects send (preamp out) on the amp would be the proper output on the amp to use into the powered cabinet.

There is still the 50-50% possibility that the powered cabinet will be out of phase. The symptoms of this is a decrease of low frequency response when the powered cabinet is added to the mix.

Is there a phase/polarity switch on the input of the powered cabinet?

I'm just crazy. I lke the dirty sound the Hartke makes but I would like a deep sub sound that the Whappo can give.

Shoot. No pase switch on the powered cab.

If they're out of phase, you can build or buy a cable which reverse phase.

i dual amp

1. I use a stereo ric 4003 with a stereo spitter box. One (bridge pickup) to one amp with my overtrive effects, second (neck pickup) to my other amp clean/compressed for my clean lows. Overdrive and Mix to taste.

2. Any bass into my darkglass adam pedal. It does a overdriven line out to one amp, and a compressed clean line out to my second amp. Blend to taste.

the adam can also blend both as one signal to a singe amp for a similar effect… but sound guys will prefer the first option if you line to the pa for them to mix/control

I’ve been looking at this as a solution for a stereo power amp with two cabs. Are there any downsides to the ADAM?

Imho listen to the photon and adam and decide what you like most. Imho the adam has more of a “massive” sound vs the a/o distortion. But i find the crazy fuzzed out settings of the adam kinda useless. I prefer the lower to moderate overdrive options.

i think either would be awesome.
- compressor
- drive
- tuner
- multiband eq
- di box (headphones out, cab sim, ipod in)
- options for dirty and clean signal out for dual amping of non stereo bass.
- oh… and new software update… a noise gate which is just amazing!

plus… with the adam i can buy a base dg a/o, b3k, x, etc and run the adam clean… and get the other effects. At the moment there is no simple version of the adam’s distortion circuit.

I use Radial Bigshot ABY pedals to solve most all of the issues you'll probably end up having when running dual amps. Powering both amps from the same wall outlet/circuit can also help reduce noise issues.
