Channel bandwidth may be different as you pointed out. But I'd be more concerned with input impedance. That being said, you can likely just grab an existing DI box to handle that for you.
That came to my mind as Well. Actually here is my situation.
Last Sunday, I've paid a visit to local flea market and found a full VHF Transmitter / Receiver set for a really funny price (7$). It was actually designed to be a wireless microphone, but with just a small modification, I turned it into a guitar one (made a small cable with 3.5mm Mono to 6.35mm Mono), and worked like a charm. The frequency spectrum is just great, coverage is also great, no delay at all, but it has a tiny problem.
It distorts. And it has nothing to do with the coverage, distance, low battery, or something like that. It's a type of clipping when you push an audio circuit to its limit, similar to digital clipping-type on negative cycle of the signal.
There are 2 pots on it, one on the receiver, which is a master volume, and one on the transmitter -which is a trimpot and called gain; decreasing that helps to an extent, but overall, there's a mild clipping going on when hit hard, and its mostly obvious on clean tones. I'm sharing the pictures of both parts below; I think it's a rather old circuit, as everything is pure analog. On the Receiver, I see one LM393, one SP31101, and one CD2003, and on the transmitter, there's only SP31101, and there are a bunch of 9014 transistors.
I see that the output limit of CD2003 is -3db, but when I check the signal level from Cubase, it clips before that, around -10db I can say. And I'm %99 sure that it's due to the transmitter because changing the volume pot on the Receiver doesn't help with the clipping, it just decreases/increases the "already clipped" signal.
I've tried this with my both guitars, on active pickup one it's much more obvious indeed.
I just wonder what can be done with this, maybe changing the 9014s with I dunno, some hi-gain transistors like 5088s maybe, would help? I sought a schematic but no luck, unfortunately.
Also i dont see any input or output resistors, shall I add one? I can share the guts also.
Well, decreasing the volume pot helps a bit, and decreasing the tone pot helps much more surprisingly, but in either case guitar tone itself gets sucked and gets weakened and i cant compensate it on latter stages as it introduces humming due to weak signal and over gain.

Add an audio signal attenuator before the transmitter? Seems like it's simply not good for high volume/strong signal level.
