Hammond AO-35 Complete Start to Finish Guitar Conversion & DEMO
Вставка
- Опубліковано 6 жов 2015
- In this video we will follow the complete conversion process of a PAIR of 1950s Hammond AO-35 reverb amplifiers. We will look at the schematic and discuss various changes and mods that can be done on one of these, we will watch much of the actual work as it is being done, follow the thought processes behind each decision, and finally we will test out the tone and hear this 1950s fire-breather roar to life! This s a long video, so grab some popcorn, pull up a sofa, and feel free to grab your own AO-35s and follow along like a cooking show. If you prefer to just skip to the nitty gritty, the tone demo starts at about 1:29:13 in.
Enjoy and please share! Thanks for watching!

I got an old 3022 Hammond up local for free with a tomorrow deadline. If it doesn't go to someone who wants it, the universe will grant me an amp project. The body of the organ will make a nice guitar studio workstation. Going to place boards where the double keybeds are with rackmounts for some rack gear and the front flat surface will house a vg-99 roland and a Boss GS-10 desktop units. Place a monitor and a power head on top, change out the speaker depending on how it sounds and smile accordingly. This video is a massive help as a primer. So thanks for doing this Brad! You rock!
You know why your channel is the best and so do I. I am an electronics engineer/technician and love what you do in these videos. Now I am a subscriber and using youtube more and liking the videos! Gonna be having fun with amps when I get some dough going. Thanks for the killer channel!
Amazing sound, well-worth the time and effort you put into it, Brad.
".....and if your amp is a monster...."
Got me one,but 67 year old resistors probable drifted,sent mine to Mike Moser,Frugal amps,he wired it up point to point,matchless spitfire,all new caps,and resistors,sounds amazing,volume,tone,master volume,power,and standby switch,iec cord with fuse holder,Jewell indicator light,top notch work.
This woman gave me an Hammond organ today and it's got the same amp that you just converted...man I can't wait to do mine..thanks so much for your video ....Your awesome dude...Thanks for what you do...God bless..
I greatly appreciate the help I'm starting my build this weekend and have been thoroughly studying your video. I absolutely love the outcome you got from this setup. Thanks again I always look foward and enjoy all of your vidoes!
Great video. Thanks for sharing this. I had a Mitchell 15 watt tube amp 6w6 changed to 6v6 came out of a record player early '50s converted into a guitar amp. GREAT sounding tone
Blown away by the amp build demo. I got one on the way and am so pumped to get going. Hope to get similar end results.
Nice Ultra GS! I picked one of these up earlier this year, and I love it.
Sick amp, really does sound good. And sick UFO! It has that nice singing tone to leads with some attack. Not at all harsh despite all the gain and highs. And pleasant crunch. This as two channel amp with cleans having some headroom would be perfect.
I love work like this! Kudos! Totally cool of you to post.
Love your videos.
I really love it when you have a good build and get all fired up...
I tried running the shielding cable to the plate on an AO-35 based Carmen Ghia clone and ended up picking up a few radio stations in my signal chain as well as effectively eliminating any bass from my tone control, YMMV I guess. On another note very informative video that was invaluable in my journey to finishing my build! Thanks!
Tip when drilling into a chassis which is already populated with wiring and components, is to use electrical tape to form a little cup, stuck around the rear of the intended hole, to catch the swarf as it gets cut by the drill bit. Saves having to chase the bits out of the chassis before you dare to switch it on.
Thanx Brad, I still miss my M3. I dont play keys well but I loved playin' that old Hammond trying.
1950`s you say? its like somebody just delivered it in a
At about
I built a whole amp on my channel from stat to finish as and it took so many hours. I enjoy your videos. Wish it was longer.
