One year ago I bought a Swiss-made KHE ACS 8x4 amplifier/cab rack mount switch box to make switching between my 4 amps faster in the heat of a session. I don't think I've posted about it here before, but as I was using it today, I started thinking I ought to do a post. It's that good.
I give all credit and thanks for this to Elvis, who hipped me to it.
It works as advertised - can switch between 8 amplifiers and 4 speaker cabs, completely silently. Yes, indeed, the switching is noiseless, no clicks, pops or static. There is no tone suck. In fact, it has a very high quality buffer built in for long cable runs from the switcher to the amp. It has inputs for guitar and/or pedalboard on the front and back panels. The I/O is isolated, no ground loops. Has MIDI. Has a built-in loop for an attenuator.
Did I mention that there is no tone suck and that I am a complete maniac about tone suck? I did? Well, there isn't any. What goes in, comes out.
In other words, for switching between amps, or between amps and speaker cabs, etc., the KHE ACS 8x4 is absolutely perfect. If you're a serious maniac with more than eight amps, no worries, several switchers can be daisy-chained, and the daisy-chain can be MIDI controlled.
If you need to switch effects loops to your amps, they have models for that, too, and they can be incorporated into the system. You can put together a whole rack of this stuff, if you're that person.
As icing on the cake, the switches are one-touch electronic toggle switches that are irresistibly cool. They're so cool I don't even want to use MIDI with them, though that's in the plan, too. The thing is built like a tank, and everything about it is top-drawer.
I have no affiliation with this company. I haven't even corresponded with them in a year since I got the thing. I'm posting because this is a product that works. If you're into amps, and have 4 or more, this is your huckleberry. I figured you might want to at least know about it.
There are a couple of similar switchers that merit mention as well:
The Ampete out of Germany does similar things, and the Kahayan out of Spain is also similar. There are detail differences, but the bottom line is that all of these are terrific studio tools. If you don't need cabinet switching and have three or fewer amps, the Lehle 1 at 3 SGOS amp switching pedal is fantastic as well - but it won't switch speaker cabs.
Here's a link. I'll post a pic later today.
