    @Buco : I abosulety agree that the brain often times paves the road if you pracitce it regularly over a long period of time and figures out which movements may be f.e. inefficient. Glad it works out for you now. A bit different, but when I struggled with blues bendings where you bend the note and then apply a fast vibrato after the note already rings for some time in the bended position what really helped me was to think about how to apply pressure and from which "starting point" of the hand position. Like how to hold the hand before even applying the vibrato and also to think about f.e. pushing the string from "underneath" instead of just doing it like you would do it if you play normal notes.

    Regarding the Impulse Responses, yes I applied the IR on a regular recording. In my understanding IRs are nothing more than a sort of fixed EQ settings which makes the comparison from @ChristopheCarington with the LUTs in video quite fitting I think, which are also fixed settings in color grading. I used the Pulse IR Loader from Lancaster Audio (it's free). It's intended to be used as a guitar cab simulator but you can also just use it to load any IR file into it:

    @ChristopheCarington from time to time I fancy the idea of getting a vintage micro from the Django era but this way is definitely more flexible and with less hassle and fuss.

    @TchangoVidal Oh wow, that was news to me. I'm glad I asked and thanks for explaining.

    Hello all,

    I've been using the Tone Dexter for a couple of years now and it definitely improved my live acoustic sound.

    I had a weird experience yesterday when I was creating some new wave maps with different mics. I have always just trained my **** in my living room. This time I set up my PA in my home studio, with is really dead, and programmed the **** in there. When I played thru the wave maps (including those that I had previously made), I could hear a slight reverb or delay. My new wave maps were recorded in the same, dead room with the mics about 6" away. If I switched to just the straight piezo pickup it was immediate and dry as it should be... but sounds like a piezo, which is why I bought the **** in the first place. I'm assuming this is normal and that I've just never noticed it before because I've always been playing in a "live" room? I am also suspecting that it could be latency I'm hearing since it's an IR pedal.

    Any other **** or IR pedal owners experience this?

    Thanks!

    Brandon

    In the never ending quest for good live sound, I have found that in venues that require more volume, I am more susceptible more to feedback with my CJ sensor through the Schertler David amp. Set up works pretty well for most quieter settings, but when I’m pushing volume, it becomes more problematic. Have also become more annoyed with how microphonic stick on pickups amplify everything you touch on the guitar (like my right hand fingers and nails brushing and tapping on the top of the guitar) as opposed to just primarily the sound of the strings.

    Have decided to order a Krivo Pick Up to deal with the larger venues. I’ll live with the more electric sound for the sake of convenience at the moment. May even try something interesting: blending the sound of the sensor Pick Up with the Krivo Pick Up through the amp using both channels and mixing accordingly.

    Ordering the Krivo pick up, however, has brought me back to reconsidering the LR bags Voiceprint DI. I think my original problem may have been that the IR signal as triggered by acoustic pick ups like the sensor, manouche, and other microphonic pick ups may not have worked well with the voiceprint. Have read discussions here about how well the voice pprint and other IR impulse boxes work with simple piezo pick ups, it makes me wonder if it will work better with a magnetic Pick Up like the Krivo.

    They tend not to work well with a magnetic pickup. But experiment away!

    Stephane Wrembel has used 2 pickups for a long time: an ischell for more of an acoustic sound and a magnetic pickup like a peche or Kleio for extra volume for leads. It seems to work well for him.

    I tried this two dual pickup business the other day. Krivo plus Manouche mic. Too much futzing around and while testing it I realized how good the Krivo is for rhythm.

    @Chiefbigeasy why not get a cheap piezzo? They seem to work really well. And also shouldn't CS be able to do a job capturing the IR?

    I have two setups I use fairly successfully for louder venues. The double pickup setup explained above (hate 2 wires) I get both the acoustic and magnetic sound w/o feedback and the Tone Dexter which requires of course the Piezo. It definitely has the acoustic quality and does not feedback till one gets at high volume levels. I have noticed at high volume levels where there is lots of crowd noise (mostly because many people are not listening to you) the acoustic sound gets so thin anyway there is no real reason not to just play a magnetic. In those instances an amp that breaks up a little is fun or a light overdrive pedal to give that late electric Django sound is great. There is a new Tone Dexter out supposedly in November.


    When I read "restores the rich body sound" I wonder if that is good for a Gypsy Jazz guitar....guess we will find out.

    That new Tone Dexter sounds really compelling.

    I’d heard of the Baggs Voiceprint and the Tone Dexter, and both looked promising but the price tag has been a bit of an obstacle. Thanks V-dub for demoing a “more affordable” option. The NUX seems like a good choice for players on a budget just starting out with this amplification stuff.
