Hi. I have a somewhat clmplicated setup. Using two amps, two ps2a’s and one cab. The two amps is inserted in two different loops on my pedal board. The output of the board goes to fx return on one of the ps2a’s.
The first ps is just a dummy load. I’m taking the line out of the ps back into the board. Handy with the level control on the line out so that I can match the level to the other amp.
Anyway. I noticed that the flat/warm/deep and flat/brite/edge switches work the opposite way of how it’s supposed to on the line out. Is there an explanation for this? Or is something wrong?
The ps I’m taking about here isn’t even powered on.
Let’s focus on flat/warm/deep, I notice a subtle but clear bass boost when in deep mode. Are you saying that you get the most bass when this is set to flat.
Hi. I actually couldn’t hear much with the bass switch.
But I could swear the treble switch worked opposite way. But now that I got it miked up in another room I can hear that I was wrong. Works the way you would expect.
Still can’t hear any change with the bass switch.
But anyway, I’m a bit surprised that the treble switch works on the line out. Without any power connected.
I thought they were connected to the depth and presence knobs. But that’s not the case?
The switches act on the reactive load. Presence and Depth act on the power amp stage.
To your original observation, if you stand too close to the PS with your amp cranked, the magnetic feedback between the reactive load and your guitar pickups will result in a magnetic feedback loop that will cause the switches to appear to do the opposite of their intended function.
