Wireless on DB

[PaulKing]

But of course Jack ... you must have a pre-amp mounted to your bass right?

In which case this is what you're getting:

 

5. Schatten Mini-pre into Joyo. Lush, perfect. But it needs that pre-amp!

 

Move along now.

Preamp on the board rather than on the bass itself, but yes.

 

Can't help but notice that most of the 'extra' response seems to be below 40Hz ...

Are you using a piezo then?

 

I have two piezos on the AliKat, but a Schaller 411 on the Alcoa, and the BSX Allegro uses a multi-sensor piezo bridge system coupled with active circuit Bartolini electronics so it's piezo Paul, but not as we know it.

Do what?  Bunkum chap!

You're totally right the cut gets bigger as the frequency gets lower. That's exactly what an impedance mis-match does!

But look at it, EVERYTHING below 1k is significantly cut. That is a huge loss of energy at the bottom end. LUFS meter would plummet with all that meat gone!

Honestly, if you could hear the audio of those signals, it was a really big difference.. like someone rolled the bass and low mid knobs on your amp down to 1. 

So I answered my question: YES the JOYO has a normal / general purpose (ie low) input-impedance (presumably 220kOhms). Perfect for bass guitar, or pre-amped signal, but rules out using it without a buffer/preamp/active circuitry between the piezo and the transmitter. For me. 100%. Cos otherwise it's only sending a shadow of the signal coming out of the pickup (as my ears clearly told me, and the spectrum shows).

 

If you had to, you could EQ it to boost those missing low ends, or cut the mids and highs to level out the signal before boosting everything... but you're building a noisier, more feedbacky signal and it's all just a bit... urghh. Why throw away half your signal then try to artificially boost it back? 😆

 

Course it doesn't matter a jot if you HAVE got a preamp BEFORE the wireless, or active electronics... or even a mag pup like whot you got. 
I just want as little crap as poss hanging off my bass ... even if the Schatten MiniPre is only the size of a sardine can. 👍

 

I shall enjoy using the JOYO with my bass guitar, as I'd intended in the first place. Thanks for the recommendation!

I did try wireless in the end but it all felt a bit 80s to me so I went back to a trusty old cable.

 

I respect the level of effort that has gone into this. It will not be forgotten.

Do you ever have trouble with the Line 6 dropping out in a crowded gig with lots of people's phones on that 2.4GHz band?

 

I read on another theead that people have been finding 5.8GHz more reliable.

 

Thanks for posting those spectrum plots.  The G10 must have a pretty chunky input impedance.  Some people have been recommending the NuX wireless systems.  Has anyone tried one of these on a DB?

I've used a SmoothHound system with both a Shadow piezo pickup and a Krivo magnetic and it seems to work fine with both, so I'd infer that it's working at a higher impedance level, although I don' t have a way to measure it.
