I built this solid state mic preamp following a schematic found here:
http://members.tripod.com/gillcar/id24.htm
and theory found here:
http://gabevee.tripod.com/sstubepre.html
It is supposed to sound like a tube amp. Was it successful? You decide! Leave me COMMENTS down there, and tell me what you think... I think it sounds pretty good, but never having owned a tube amp, I can't make a definitive answer as to whether or not it sounds like a tube amp! Definately sounds "smoother" than the SS preamp in my PA though, and it seems to sound smoother than the Pignose by itself, which is pretty good in my book!

  • isn't the whole purpose of a tube amp to get good distortion? i didn't hear any distortion. it sounded kinda clean and blan, like raisen bran, without the raisons, or wheat gluten for that matter.

  • Do you play amplified harmonica? I'm asking just so I can have some context to your comment.

  • i liked the sound you were gitting allot is it tube like close as fare as i can tell whth my headphones i would like to hear it throught a amp with a 10 or 12 in speaker but the pig sounded good also how do you like the fab delay i have been looking for a cheeo delay for my guitar to fatten it up a bit and how do you think the preamp woutd work for guitar

    thanks Slim

  • Hi Slim, thanks for the comments! I like the fab delay just fine. If you check my channel you'll see in another video that I ended up modifying it for an adjustable delay time (added another pot) and switch out the the input capacitor for more bass. After that I think it becomes more like a $60 pedal rather than a $15 pedal. As for the preamp, I'm not sure how it would sound for electric guitar. I play my cigar box guitar through it and it sounds good, but it has piezo pickups...

  • was it easy to build

  • These things are relative... It's certainly the most difficult thing I've attempted so far... I built it totally from parts and with out a printed circuit board. i had to design the layout and use "perfboard", which was fairly difficult... If you know how to read a schematic, can solder properly, and maybe have a little experience building circuits, then I would say this is pretty easy...

  • Love that earthy, reedy distortion sound.

    Do invest in a good mic though. Shure bullet is good but I find an SM58 easier to handle when controlling your mic position for different volume and sounds. Love that sound though. Keep tweaking.

  • i like the sound you got there. personally all i have are solid state amps so thats what im stuck with. i don't use anything but delay and once in a while chorus. but i found keep the treble low and mid low with a bit of gain to be the best using a green bullet. but am always looking to thickin it up. i use a fender m80 and sometimes a ampeg ss combo. to the point where i need to get a harpgear amp to get what im looking for. but your diy vids are sweet for the elec challenged like me

  • i want try this concept for guitar amp. We are currently use fet4tube emulation.

  • You made it your self - great. Replica mic - I-mic , good work man.

  • creamyfilling102 - a tube amp is for a warmer sound that a solid state(preference) not distortion

  • yea. i play amplified harp. personaly, i just use a guitar distortion pedal to get a somewhat decent distorted blues sound. yours sounded more clean, so if that's what you're going for, then have at it it guess.

  • Just came across this.... After reading some of the comments, I assume that you continued to develop this. To me it only got about 15% there. Keep up the good work. I'm one of those who refuses to play with a Bassman. I use a Piggy G60VR tube amp with a Weber speaker, but am considering going solid state.

    Peace
