Amp switcher box, multiple amps going to one (or two) cab

[Skywalker83]

Ok so i have two bass amp heads that i use, a Warwick 3.2 Pro Fet beas head, and an Ashdown Superfly 1000

Both amps have very different tonal capabilities and i was wondering if it was possible to make some sort of device that would allow me to have both amps connected to one or two cabinets and give me the ability to swicth between the amps when i wanted.

The Warwick has a single Speakon output and the Ashdown has 2 speakon outputs (each output is 500W). The speaker cabs also have Speakon conectors.

Anyone know of any Schematic sthat would help me build such a device?

I've mad a box that took a signa and split it into two identical 180 degrees out of phase outputs for use in using a standard stereo amp in bridge mode, but you're talking two different amps with different tones. Just run two cabs

Hi,

CAE and Bradshaw, Rolls, Radian, and DMC all make Rack Switchers that operate multiple amp rigs. The Rolls unit is the cheapest at $125......... all use relay switching, and a midi footswitch set up. I use the DMC Ground Control with their programmable footswitch with display.................$2200.

Dig around on the net for Amp and rack switchers.

I'm sure that there are also numerous speaker cabinet switching boxes similar to studio A/B/C monitor selectors or Speaker Demo Selector switches that can be had as well. One should be able to find diagrams of these devices somewhere on line.

You may consider a cabinet for each amp.............and an A/B/Y switch for your Bass to use either/and/or setup.

I've played with Bassists that kept a backup rig, but never 2 rigs together. Kinda overkill. I would think the dynamic of the instrument would suffer from too much going on................. losing the actual tone of the Bass guitar that we all love. It is more than just low end and power that makes a great Bass sound................Tone.

All the years I operated major Sound Reinforcement, the best sound I got from all the bass rigs was a DI from the instrument before the amp and a mic in front of the cabinet. 90% of the sound would be the instrument...........with a little of the amp sound mixed in. Great tone this way! 2 distinct sounds blended at the mixer.

Your Bass rig is basically there to monitor your instrument on stage anyway not to fill the room. That is what the PA is for, right?

If you use a particular preamp separated from multiple effects and multiple amps.............the rack switcher would work.

Hope this helps.
