no, actually. I just figure TRS would cut down on the amount of jacks. (Lets make it a DB25 connector if that's easiest!)
The only fixed thing I have are TRS insert points on my mixer, and TS plugs on the pedals.
I figure wiring 16 TRS jacks on this repedal "magic box" would be easier than wiring 32 moon jacks..
I'd even be open to have the cables hardwired to the box if that works out to be the easiest (I could wire that myself...)
crochambeau wrote:My gut instinct is telling me this is probably more of a levels/gain staging issue than that of impedance mismatch. Low source impedance is rarely ever an issue so long as the levels are good, and *as far as I know* once you make it to the insert stage of the mixer you're in a line level (higher impedance) unbalanced domain anyway. I might be wrong on that one, as all my insert experience is with a TRS to two mono cables in a send/receive configuration and to my knowledge running a balanced line on two conductors returns an unbalanced signal.
inserts are unbalanced. I say TRS because it's got a send & return on the same cable.

Lowering the gain, I assume that's easy with an attenuater
adding gain... probably harder to do?

Be warned, the cheaper you go on the transformer the more likely you loose bass
I'm not going to hem and haw expecting 20-20k frequency response. This is just to plug distortion pedals into my mixer inserts without them sounding completely gutted due to level/impedance mismatch (as they do now). pedals I have set aside for this job: Dwarfcract HairOfTheDog, Devi SodaMeiser, IronEther oxide, BOSS - ODB3, Boss DS1.... etc. stuff to fuck up multi tracked drums. I can always do band-pass crossblends with the original signal as needed...
I have
eventide pedals that let me select line or guitar levels on each the input/output. and using those inline to match the levels always works. Since they're stereo I can I'll put one mixer to eventide with inputs set to "line>guitar" --- then plug desired distortion guitar pedal, then back into a second eventide with the switches set to "guitar>line" and back to mixer. Both eventide pedals are set to bypass (and since they're stereo I can do this for 2 channels... but there's no way I'm buying 8 eventide pedals JUST for level balancing! LOL)
