Definitely desk based for me.For those who are already working on something similar to this, how do you plan to use it?
I've had the ggg mxr board laying around for a while half built. I planned to use it on my couch/desk top console style with toggles like you're suggesting with a few other circuits but I may put that in a smaller travel style enclosure if you're planning to release something with more features and tabletop appropriate. I'd also be into something like that for sure.It could be buffered, or it might be removed (or replaced with a basic reverb after the cab sim)...
Initially I was imagining a simple way to switch a loop of effects in and out with one press, but at this point it's still in the air.
For those who are already working on something similar to this, how do you plan to use it? On a pedalboard?
Personally I'd be more likely to sit it on a desk in front of me, as a console-type unit, with toggle switches rather than footswitches.
you could use an adapter cable to change center positive to center negative. do you know if it will run on 9v? or do you have a 12 feed you could use for it from your pedal power supply?My headphone setup is a UniCab into one of these, a $20 knockoff of a knockoff. Works, though, and sounds good.
I have no need for the XLR sockets or the mic level pot. The mono/stereo switch is useful, though - it's for the input, so it lets a stereo input through, or splits a mono input into two outs, one for each ear.
It's not that loud - but that's a good thing, for a headphone amp. I usually have the level at about 70-80%.
Only thing I dislike about it is that it takes 12V center positive power, so I have to be careful setting up and I can't just run it off my pedal power brick.
I'd prefer toggles to footswitches, but maybe have options for either, so the builder can choose. Or at least make it so that it can be modded without much extra effort.
I have both those things, but using them wouldn't be less hassle than just using the power supply that came with the headphone amp. I guess I prefer to keep center +/- far apart. I was more saying that it'd be nice if the headphone amp just used the same power as my pedals.you could use an adapter cable to change center positive to center negative. do you know if it will run on 9v? or do you have a 12 feed you could use for it from your pedal power supply?
All great points. My recent headphone amp build is limited to mono setup (fine for guitar-actually sounds quite good). For the aux input you really need two headphone amp circuits to keep it stereo and I agree that something that could drive the cans a bit more and get better quality reproduction of whatever tracks you’re trying to play along to would be good.To add my own input...
I built a headphone amp a while back that I absolutely love, and I'm in the process of building a second one for my father. It's a community-designed circuit that AMB sells the circuit boards for called the M3. It's not a terribly expensive build, but it's certainly a bit more than an average pedal.
I've got a little collection of cans...nothing too crazy or ridiculous. It's easy to get up one's own ass when exploring the audiophile world. I tend to use mine with a pair of BLON planar magnetics or my Sennheiser HD 6xx.
Something that I really appreciate about the one I built is it's sense of "space" in the stereo image and quick tracking of low end transients. I've attached the schematic, which is open-source.
Something I've noticed over the years is that the majority of the commercial guitar headphone amps I've used have felt pretty claustrophobic and sterile, more of an afterthought and a race-to-the-bottom make it cheap cheap cheap toy than something I'd actually want to spend time with. And using one for bass...typically ends up being a smeary, unfocused mess.
So...that is to say...it would be really cool to build something with enough "oomph" behind it to drive a pair of circumaural cans competently, enough capacitance on tap to cleanly reproduce the low end transients of a bass guitar, and something that sounds more akin to the "amp in a room" soundstage than the typical "hey bud get your ears ready for this mono exploration of sandpaper and ice-pickery".
Again, it's easy to get up one's own ass when it comes to the world of audiophile headphones and amps and cork-flatulence-sniffing, BUT...there are little pieces to be snagged from that world that could be utilized to create something quite capable and FUN to use.
Granted, not everyone's gonna have $200-300 headphones to enjoy it with, but my vote goes toward "overbuild that shit".
