Welcome to JonBouye's Backyard!

Thanks man, appreciate the kind words.

yes we all doing good .. Got a big cook out we gonna  do this weekend  ,,, Benn working on a git for my great grandson ,, his mom wanted the neck painted RED ,, so I did ,, I wouldn;t have done it ,, but gotta admit  after it was done ,,looks really good !!!  Learn something on every one u make !!       U ok ?  Really liked ur little amp  sounds good ,, I gotta get into the wiring a little deeper ,, I think would b an added attraction if u had a cigar box amp ,,battery powered ,,when u showing for sale   ..

 

I'm happy to be one of your new friends now...°<[:-) [---]==={

Thank you for your comment. Well, with regards to this moveable chord system. Start simple. First learn how to name the notes on all 3 strings. There are only 3 basic movable "Major" chord shapes. One gets it's name from string 3, the next from string 2 and the last shape from string 1. Then it is just a matter of understanding how the "Major" chord shape is altered. I know basic music theory can be challenging at first, but once you understand it, finding the chords you need becomes routine. Always feel free to write and ask questions. I am quite sure others will benefit from your asking too. Enjoy your practice, Keni Lee  

hey thanks jon .db.

Jon...I'll check out Rod Elliots site.  I think that if you have any background in electronics at all, you'll take to LTSpice.  I can help you with what I know.  It's easy to model a circuit, and even predict the frequency response.  You can see when a circuit will start to distort, check harmonic content...a really nice piece of 'free' software.

 

Let me know what you think about the three designs.  I've got the tube part down I think.  I can fake the rest...LOL. 

Thanks Jon...BTW...Jon is my son's name.  We were going to name him Jean Pierre (French pronunciation) but were afraid his teachers would mispronounce it...so we named him Jon Pierre instead.  Thanks for the happy birthday wish and Happy Birthday to you dude!!!  I really do enjoy the building and designing aspect of this.  Have you used LTSpice?  It's an excellent free electronics design software package. 

I'm thinking about an amp design for CBG, but don't yet know what topology to build.  The LM386 design (Runoffgroove Little Gem and variants) at 9v just doesn't have a lot of clean head room. If you up the supply voltage to 12 or 18v then you're dealing with added batteries or using a walwart.  I built a little LM380 amp and it does ok at 1watt, but the LM380, although available, isn't widely used.  I designed a conditioning circuit ahead of it that mimics a Marshall amp.  I think the little speakers are the real problem with existing CBG amps.  Weber sells a 6" and a 6X9" guitar speaker that would be perfect.  What do you think?

i noticed in the chat you mentioned learning uploading and that its time consuming .

 

i use this free app to resize fotos . it takes a second , but then they are a fraction of the original size and upload in a flash . just thought i would offer to help , i wasted a lot of time with this before i figured out to use this app , and its free . i usually set em to like 800 by 600 .
