JHS Pedals JHS Summing Amp Input Signal Blender Guitar Pedal

I use this pedal to be able to plug both a keyboard and a guitar into the same amplifier. It makes it easy to switch between the two instruments and works well with no volume or tone change. The JHS Summing Amp is well made and I would highly recommend it.

Brilliantly simple. Plug and play. Blends two signals seamlessly. Good quality

Does what it's supposed to. Let's you mix 2 signals back into one. I'm using an A/B pedal for 2 channels and then this pedal to return them back to one mono signal. You're a smart person! You'll find some other way it's useful for you! Get one and put it on your board. Or throw it in your bag for when you need it. Because eventually, you'll need it.

I have to assume that people in these reviews getting mad about the bass guitar warning didn’t actually try the pedal. 2 points to make: 1) only very hot basses are going to be breaking a 10v threshold anyway, and 2) this pedal is very likely sitting at or near the end of your pedal chain, so if it’s clipping, then down the volume on one the pedals feeding it and compensate with amp volume. I’ve got 2 of these on my bass board (and my bass is very hot) and they’re both doing fine. Simple pedal providing a necessary service in certain chain configurations.

This review is for the Summing Amp. Despite a price a bit more than I wanted to pay, I bought this thing to solve a very specific problem. I have a stomp box electronic drum pedal that I want to chain in with my guitar so I can drum along with myself through a single guitar amp. This means some kind of Y. I've tried a simple splitter, a Y with resistors, and the simple circuit you get when you google "summing op amp." The problem is, the drum pedal has a BIG ol 2uf (two, not point oh two) tone capacitor inside to give it a deep deep bass drum voice. All the simple solutions let the drum tone cap suck all the highs out of the guitar. This JHS Summing Amp does the trick though. Two ins, one out, nothing else, and my two incompatible signals are blended together just fine. It would be nice if it had an internal battery and cost twenty bucks, but you can't have everything.

Not the sort of box everyone needs, but super handy if you do. I have a rig where I needed to merge two parallel stereo effects paths down to one stereo output. My solution was to use two JHS Signal Blenders - one for the two right channels, and one for the two left. Those output a single right and left to amps. I had been using a passive cable setup before, but it lead to volume drops in certain effect path configurations upstream. Adding active buffered signal blenders totally fixed that problem. Output is solid and consistent right to left, regardless of what's at the input. Just plug and play - right on unity gain and even balance of the inputs.

Perfecto cumple lo que tiene que hacer. Y el sonido es limpio.

Good tool works great!

mann kann leider nicht selber die Lautstärken bzw. den MIxeffekt nicht beeinflussen. Es fehlt mir eine Überblendknopf. Die Mathematik im Gerät ist nicht beeinflussbar. Hätte mich vor dem Kauf bei anderen Herrstellern informieren sollen.
