On the way back the 600ohm or so output on an audio device gets stepped up, impedance wise to 225kOHm! Once the signal is recorded, it doesn't rememeber the impedance it was stepped down too, when it comes back out of the console or soundcard it is the output's impedance that matters, which, as you say is normally a few hundred ohms, 600 used to be standard but I'm not sure if thats changed these days. So a typical guitar pickup of say 15k might be stepped down all the way to 40 ohms with a DI box, fine for going into a mic pre. I think the trouble with using a DI in reverse is that the impedance is much HIGHER than a guitar normally is. On my part, I think the resistor is unnecessary for the DI setup. My posts were polite and trying to be as informative as possible, if you think I am wrong then cool, I'm all up for being proved wrong if I learn something but there are better ways to discuss this than cheap insults.ĪNYWAY, back on topic, your posts have got me interested in researching this a bit more, and I think that we have both got it a bit wrong. Anything I post here is from experience, not from learning something at some uni course that I have never tried out. I have learned this stuff from a practical, working point of view, while boosting my knowledge on electronics etc in my spare time. I work at a big UK studio, where I learned under my boss who has recorded and worked with some of the biggest acts and albums of the last 16 years. Thats all academic though, If it sounds good, do it! Try the passive DI, attenuator, resistor method first and see if it gets the results you want!Ĭlick to expand.Whats gotten to you? Thats a bit unneeded and offensive, I have never been to full sail, nor am I completely sure what it is but I'm pretty sure I get the implication. Using a resistor is kind of like using an impulse response for a reverb that changes over time, it will work and sound realistic but not be quite as complex as the real thing. The measurement that really matters is inductance, and that changes depending on a lot of factors including which string you are playing, where on the fretboard you are playing (it frequency dependant!) and how strong the magnets are etc. Thats why I mention the technique with a resistor, if you read my post you'll see I mention to use it together WITH a passive DI and an attenuator! The resistor is not a perfect solution, nor is the pot on re-amp boxes, but it does help get a lot of useable sounds.Īs a side note, its not really the impedance of pickups that matters, or at least adding any kind of resistor will not make it behave the same as a pickup. The transformer in the passive DI isolates the two circuits when reamping which helps stop hmm's and buzz's, but isn't the ideal simulator of a pickup! What I suggested was it does not switch the impedance of the signal, the high impedance of guitar pickups and how they react with the amps circuitary is an important part of how an amp sounds. Okay, so you’ve hit record, captured a direct take from the guitar player through the DI box, and it's gone through your interface into your DAW.Click to expand.? I never suggested it doesn't work, I know it does i use the method regularly! Other favorites include the Rupert Neve Designs RNDI, BAE Audio PDI, Spectra 1964 BB-DI, A-Designs Audio REDDI, and Warm Audio Passive Direct Box. Radial Engineering specializes in DI boxes and has a number of best sellers including the J48 Direct Box, HDI, ProDI, and a Reamp Kit. Just about any DI box will do for the task, as long as they have the proper inputs and outputs previously mentioned. By setting up this way, a guitarist will be able to play and react to an amplifier in real-time, while also capturing a completely clean signal. Plug your guitar or bass straight into a DI box and run the Thru input into an amplifier and the Out to your recording interface. DI Boxesįor those intending to reamp guitars as part of their production, the first step is to capture as clean of a signal as possible on the way in. So sit back, plug in, and let's talk about how to get pristine takes that you can do whatever you want with later. Want to know the best part? It's pretty easy to do! In this blog, we'll be going over the basics of reamping and the gear that you'll need to get the job done right. This practice gives users the chance to experiment with different microphones, various settings on amplifiers, and unique pedal combinations without having to re-record another take. Digital Adapters & Miscellaneous CablesĪs one of the most popular techniques in modern recording, reamping allows engineers the flexibility to capture the best sounding guitar takes and send them through any amp or chain that they desire.
