Honestly I use it more than my regular amp these days because I have housemates on opposite sleep schedules. It sounds really good with my guitar going straight in, but much better if I cut some of the lows with an EQ right in front of it. It doesn't take most dirt pedals well (perhaps this would change with a cab sim in front), but chorus, octave, delay, etc. sound great. I was ready to be disappointed by this headphone amp, but I now consider it an essential piece of my gear collection.Old Reliable Musichttps://www.blogger.com/profile/04652409969197254388noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-78105698766001354982020-09-23T00:26:27.696+01:002020-09-23T00:26:27.696+01:00Works great.

I'm thinking I should change the pot as I would like some more control over the level. <br />Also it might be worth messing around with resistors and omitting the pot entirely. <br /><br />Does anyone else have this issue?Anonymoushttps://www.blogger.com/profile/01824506842697547759noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-43680651015532452322018-04-08T09:52:51.566+01:002018-04-08T09:52:51.566+01:00Hi,

But I was thinking to completely bypass the Amp, so keep the input music player stereo, and add the output from Amp, mono, to the output. I don't know if this will work or a stupid idea. Do I need to ad any resistors or diodes in between the mono to stereo output?<br />ThanksAnonymoushttps://www.blogger.com/profile/17190643080108980446noreply@blogger.comtag:blogger.com,1999:blog-6847048658257278783.post-54334579253917856472018-03-07T14:49:39.625+00:002018-03-07T14:49:39.625+00:00Excuse me sir ..

I used a 500K linear because that's what I had, but the sweep goes from on (and pretty loud, about where most people like headphones), to suddenly massively loud. I know to expect a sudden transition with a linear vs. rev log pot, but this sounds like an on-off behavior. Just for kicks I replaced the pot with a 5M resistor and then took it out entirely, and got the same volume as with it all the way off. I did use 3904/06 for Q1/Q2, but I expect pretty much everyone who has built this will have done the same.<br /><br />I'll go through the normal debugging steps, but was hoping someone could shed light on the gain control issue. It's still very usable, just a heck of a lot louder than I want it. It's an exceptionally clean circuit with a very "Hi-Fi" sound, doesn't sound much like a guitar amp but that's not the point. If your headphones are any good you'll probably want to roll off some of the lowest bass and highest highs.
