Wow, that really sounds great!

What voltage are you running the preamp and power amp at?

zoohr · February 26, 2007, 03:07:10 PM

preamp at 10V power amp 35V. The ssss noise is from snare drum. Recorded with DV cam.
The last section with the very, very loud band

Doug_H · February 26, 2007, 03:27:23 PM

That's really awesome.

Nice job !

zoohr · February 26, 2007, 04:09:27 PM

I must thank You Doug and the guys from runoffgroove for inspiration from your great work, and sharing all with us!

I'm not going to get on here and do the typical vulturing for a schematic, but I'm curious... Did you use a popular amp schematic topology for your jfet preamp?

It's nice to hear such a good sound in a SS amp. I have an old yamaha SS amp and recently tried the "drive" channel again. I was surprised how good it sounded. Not as good as yours, but it has potential.

My jaw dropped when I saw the depth of the amp. It really is small.

Darn, now I want one.

Hey, you cut your hair and shaved for the band-take? Haha, just kidding but do you ever get to play the six-string in that band? You sound better to me than the 'other dude'.

First, my english is not so good, so i have problem expresing my self.
I have modified schematics so many times, because i had problems with noise and oscilations. I post schematics soon when i find some time.

Really cool sound. Even better than my stock Kustom 16. Mind to share the circuit design ?

km-r · February 27, 2007, 02:36:35 AM

now i wanna build a similar amp 50 watts[whats!] with some DFX!!! thats DIY-Effects...

km-r · February 27, 2007, 02:37:29 AM

yes, a circuit diagram would be very helpful for your followers... *ahem*

koulis · February 27, 2007, 03:26:52 AM

Very cool sounds! Bravo

Hope you share your secret with us

MartyMart · February 27, 2007, 04:04:45 AM

Nah, I don't need a schematic, but thanks. I'm just curious about what your approach was.

mac · February 27, 2007, 01:00:27 PM

I'll like to see that schem

4049.. CMOS, aye?..
them chips are definitely a pain in the tube's ***...

sounds really good. Nice strat I guess too.

I really like Gilmours shining diamond licks too!

They are just written for strats!

Sorry guys, I was offline few days and I will be offline for weekend and most of the next week. I have problem with my Internet provider.
I have some pictures for you!

zoohr · March 02, 2007, 03:06:50 PM

I forgot one.

grolschie · March 02, 2007, 03:58:41 PM

Nice! Are you going to start building and selling these? Or will you post a schematic at some stage so that we can enjoy the mojo of this amp too?
