I am constantly amazed at people like you John, who are prepared to sit down and EXPLAIN the way things are and work, so people can understand things better. I was wondering if you could answer a question for me? Would you happen to know if I could just plug my Tascam USB interface, into my Samsung Galaxy Core Prime to use on Amplitube for Android? I think I could, if I just buy the right USB cable that fits into the interface and the Samsung phone. I am on a very tight budget here at this moment in time, but I am mad looking to play bass on something and the Samsung phone is the only way to go for me right now with the money I have.
+SDRockman - I don't have any experience with android phones so I can't give you a definitive answer. Not sure if the Tascam USB interface would draw too much power from the phone, or whether the phone would recognize it and have a driver for it, etc... Try it- but buy the cable/adapter somewhere you can return it if it doesn't work :)
+John Cooper I think it wont work after all because it did come with a CD, to install a driver for whatever operating system you had. But I will try buying the USB cable any way lol As you say, I can always return it. Thanks!
You are THE MAN John! You must be an electrician at your day job? I'm going to school soon for electrical engineering. EXCELLENT VID!!! A+ Thanks for making vids, and keep 'em coming!
Thanks for this video... just pulling parts together and seeing what I'll need to purchase. One use I had in mind for this was as a virtual pedal board. I'm assuming that I can add a stereo 1/8" to Mono 1/4" jack to the headphone jack, and connect to my amp's send/receive loop. Any problem with that?
hey man, i'm definately gonna do this! thanks. just for interest sake, is it only impedance matching it does?(apart from splitting the signal) if so, will a normal D.I. Box match the impedance, if i use the right connectors? it would mean a lot less soldering....
I've used the 5457 as interface to my laptop but I'm having a hissing sound though. Is there other way to do this? I did connect my output to the laptop mic input and the latency is acceptable but I can't stand the hissing noise. Thanks in advance John...
hello, ive been trying this on my ipad mini and it dont work. now i try it on my cell with an android app and it works(i dont have the JFET yet). i dont even have the 2.4 volts out the ipad. i get -1.8 i nned help please!!
Hi john i made the iDevice, but my ipad 3 don't detect a headset input only like headphones, so i can listen but it don't detect a mic, and is the same with or without the jfet. Only detect the ordinary handsfree. Can you help me?
I recommend you test the circuit on breadboard as I demonstrate in part 2: Simple JFET Preamp for an iDevice guitar Interface, part 2 The circuit is much easier to experiment with on breadboard, to make sure it's all working.
Hello john i have a little problem when i connect headset theres no sound,but when i remove 1of them it has sounds either 1 of them i put the sounds ok but together thers no no sounds
Probably some wiring mistake. As usual, I recommend you build and test the circuit on breadboard as I demonstrate in part 2: Simple JFET Preamp for an iDevice guitar Interface, part 2
The JFET in this circuit requires power. If your laptop has a powered mic input, it might work. But not if you only have a line-in. Check the input with a multimeter to see if it carries a DC voltage.
I don't know- there are so many different android devices out there- and I'm not sure how consistent the hardware is. You can rig up a test plug for your headphone jack and use a multimeter to check across the mic/ground pins to look for a suitable voltage.
This interface introduces no additional latency, since it is using the microphone input of the iPad. The audio app running on the iPad typically has some settings to control latency vs quality.
I always enjoy your videos. As an electronics major and weekend guitar player, you always have cool projects and things to keep me inspired!
Great demonstration, great explanation! You and your channel are awsome, John!

you big tease!
Cant wait for 2 and 3, love your videos!
Thank you. you made it look so easy

We have to buy the programs or not? I just download it and do it through your video but it can't wark. Could you help me please?
thanks for your information.
another question do you know what is ettus research USRP n210 and what it does to an ios device?
Not a hissing sound but more of a steady high pitch sound (Like a sound from an oscillator).

Sweet, now gimme soma dat part 2 :D
can you teach how to build the one that connects to the usb port of ipad?

are the other parts online yet?

Great to view but where's part 2?
John ! works on Macbook Pro?

will this work for an android phone ? they also have that kind of input.
I don't know- there are so many different android devices out there- and I'm not sure how consistent the hardware is. You can rig up a test plug for your headphone jack and use a multimeter to check across the mic/ground pins to look for a suitable voltage.
it can be use that in pc?

What is the latency?
This interface introduces no additional latency, since it is using the microphone input of the iPad. The audio app running on the iPad typically has some settings to control latency vs quality.
