kiki Posted February 17, 2008 Report Share Posted February 17, 2008 man, this tuner is really amazing. but i have to tell you... I have no idea how it works! you put the ball-end of the strings in the neck, right? and how you tie the string in this tuner? It's possible to do many turns on it? Or you have to pull the string before start tuning? (can you understand my doubts?) the body looks really nice too. I'm waiting to see how the Gt2 will look into it! well, I'm waiting for news!

Thank you Kiki, about the tuner : First I put the tuner jaw in the place nearest the hardtail (remember that the tuners are placed under the hardtail). Then I pass the string through the jaw. If you look in detail next pic you can see a hole in the jaw (the bigger one) to hold the ball end of the string. Then the string pass through the hardtail directly to the nut and then to the headpiece. The headpiece has screws to hold the strings. Now I have to use the tuner pegs to intonate the strings. That´s all ! Yesterday I left the tuners for the chromium plate, they will be ready in the middle of next week. Quote Link to comment Share on other sites More sharing options...
anderekel Posted February 17, 2008 Report Share Posted February 17, 2008 What sort of strings are you gonna use with this? is it gonna be double ended ones? cause if it is I don't see how you're gonna string them through. I really like watchin' the whole thing comin' together. Quote Link to comment Share on other sites More sharing options...

I really like watchin' the whole thing comin' together. No, regular strings. The ball end pass through the tuner jaw and the other end pass through the headpice and it´s fixed using a screw like a locking nut. Quote Link to comment Share on other sites More sharing options...
Andronico Posted February 17, 2008 Author Report Share Posted February 17, 2008 During the last Saturday I was working in the GT2 board : Following are the usual step by step pics : http://i264.photobucket.com/albums/ii186/a...itar/GT2_01.jpg http://i264.photobucket.com/albums/ii186/a...itar/GT2_02.jpg http://i264.photobucket.com/albums/ii186/a...itar/GT2_03.jpg http://i264.photobucket.com/albums/ii186/a...itar/GT2_04.jpg http://i264.photobucket.com/albums/ii186/a...itar/GT2_05.jpg Now I have to populate the board and test it out of the guitar.

Andronico Posted February 19, 2008 Author Report Share Posted February 19, 2008 Reporting about the GT2 board : The GT2 is completed and tested with my regular amp. It works well. This implementation has a reduced number of options because I don´t use all of them : The pots are the same of the original GT2 : High, Low, Gain and Level. The AMPs selections are : California (Mesa) and British (Marshall). It hasn´t the Twid (Fender) option. The MODE selections are : High Gain and Hot Wire. It hasn´t the Clean option. The MIC selection is fixed in Center option. I choose this configuration because I´ve been using a GT2 with my practice guitar for almost a year and these are the selections that I use. Now I have to make the battery charger circuit, more updates coming... Quote Link to comment Share on other sites More sharing options...

That´s all ! Yesterday I left the tuners for the chromium plate, they will be ready in the middle of next week. I am really intrigued about your tuner design. Looking forward to see how well they perform. The metal frame that keep the tuners together looks like aluminum, will it be stiff enough under string tension ?? Lovely work on the body design, will look killer. So you have basically eliminated the Fender Clean models from your GT2 !?!? So it's going to be all gain and saturation !?!?! Shame on you !!!!

Andronico Posted February 20, 2008 Author Report Share Posted February 20, 2008 rob_tart, LPboco & Blackdog : thank you for your kind words ! I am really intrigued about your tuner design. Looking forward to see how well they perform. The metal frame that keep the tuners together looks like aluminum, will it be stiff enough under string tension ?? No, the metal frame is iron, 1.5mm thick. So you have basically eliminated the Fender Clean models from your GT2 !?!? So it's going to be all gain and saturation !?!?! Shame on you !!!! Yes, when I turn the GT2 on it´s all gain and saturation. But I can turn it off and use the pickups without modelling... I was working in the battery charger and the power supply for the charger and the portable amp, I think that tomorrow I´ll have a new update.

Andronico Posted February 21, 2008 Author Report Share Posted February 21, 2008 Little more progress to report : I was working in the battery charger circuit, it´s based in the following article but adapted for 9V bateries instead of 12V ones. http://www.owlnet.rice.edu/~elec201/Book/batteries.html This charger is very simple and cut off the current to the battery when it´s charged. That´s good ! Then I need a AC-DC adapter to use with the charger and with the portable amp. For the charger I need about 12V and 9V (regulated is better) for the amp. I thought that the more simple and cheapest idea was to buy a normal 220VAC to 12VDC adapter (yes the bargain ones) and improve it. For this I open the plastic envelope and put a small board with a diode bridge, 7809 regulator, filter capacitors and a switch to select between 12V DC filtered output (bypassing the 7809 regulator) and 9V DC filtered and regulared output. The result is : Outside pic : http://i264.photobucket.com/albums/ii186/a...werSupply02.jpg Now, during I wait for the chromium plate of the tuners hardware (they are late), I´ll begin with the cover of the GT2. I think that make it of wood is not the easyest way but the result will be better. Quote Link to comment Share on other sites More sharing options...

Andronico Posted February 22, 2008 Author Report Share Posted February 22, 2008 really interesting this batteries. i can see that this electronic part you uderstand very well! Yes, these batteries works well. It cost four times than an alkaline battery and has one third of the power but I´m a green guy (or want to be one)...

Andronico Posted February 28, 2008 Author Report Share Posted February 28, 2008 I was working in the GT2 cover : The small black dots are to indicate the start point of the pots. I tested the cover with the knobs and switches to see if all fits well (before glued all the parts) : http://i264.photobucket.com/albums/ii186/a...RearCover05.jpg Step by step pics : http://i264.photobucket.com/albums/ii186/a...RearCover01.jpg http://i264.photobucket.com/albums/ii186/a...RearCover02.jpg http://i264.photobucket.com/albums/ii186/a...RearCover03.jpg Quote Link to comment Share on other sites More sharing options...
kiki Posted March 1, 2008 Report Share Posted March 1, 2008 very nice! it looks great with the knobs. how it's fixed in the body? there are some screw, or what? Quote Link to comment Share on other sites More sharing options...
Andronico Posted March 1, 2008 Author Report Share Posted March 1, 2008 very nice! it looks great with the knobs. how it's fixed in the body? there are some screw, or what? Thanks Kiki. The first idea was to use four neo magnets insected in each corner support and small pieces of metal in each corner of the cover. But I´m not sure if will be safe enough because there are a board and a battery inside... The second idea (and think that I´ll use it) is to use the magnets and only one small screw in order to avoid that the cover opens. If you see with attention to the following picture you can see a hole in the middle of the jacaranda strip, this hole is for the AC-DC adapter input (to charge the battery). The idea is to drill a small hole at the left of that one for the battery charger status LED and a second one at the right to support the cover in place.

Andronico Posted March 1, 2008 Author Report Share Posted March 1, 2008 Time for the portable amp. I decided to make a Marshall MS2 clone using the following circuit diagram : http://homepage.ntlworld.com/s.castledine/greenfuz/ms2.html The problem was the box but the last weekend we went to my parent´s home and looking in an old drawer I found a little amp that I used with a keyboard when I was a teen. This amp don´t work but has two 4 ohms speakers inside its black plastic box and switches that I can use. Then I took the old amp board off and replace it with a DIY MS2 board. I made a little modification to the circuit to include an input to connect a MP3 player and play the guitar using backing tracks. Here are the results : More Pics : http://i264.photobucket.com/albums/ii186/a...itar/Amp002.jpg http://i264.photobucket.com/albums/ii186/a...itar/Amp003.jpg http://i264.photobucket.com/albums/ii186/a...itar/Amp004.jpg http://i264.photobucket.com/albums/ii186/a...itar/Amp005.jpg Quote Link to comment Share on other sites More sharing options...
Andronico Posted March 4, 2008 Author Report Share Posted March 4, 2008 Yesterday I received the tuner hardware chromium plated. Following is the headpiece with the guide nut in place : More pics : http://i264.photobucket.com/albums/ii186/a...Headpiece13.jpg http://i264.photobucket.com/albums/ii186/a...Headpiece14.jpg http://i264.photobucket.com/albums/ii186/a...Headpiece15.jpg http://i264.photobucket.com/albums/ii186/a...Headpiece16.jpg Quote Link to comment Share on other sites More sharing options...
Andronico Posted March 4, 2008 Author Report Share Posted March 4, 2008 I changed something in the tuner pegs, I notice that the grooves around them were smooth after the chromium plate. So I make the hole larger to fit a small screw like I use in the headpiece. Then I can use my fingers or an allen key to tune the strings. Here is the result : The pegs and the screws : http://i264.photobucket.com/albums/ii186/a...tar/Tuner18.jpg Quote Link to comment Share on other sites More sharing options...

Bassisgreat Posted March 4, 2008 Report Share Posted March 4, 2008 Wow, this is a really PRO build! Makes me want to build a (not nearly as complex or handy) travel bass... Great work!! You could probably sell these pretty easily, I've not seen a traveller guitar this ingenius before. Quote Link to comment Share on other sites More sharing options...

Andronico Posted March 5, 2008 Author Report Share Posted March 5, 2008 Thank you for your support friends ! Bassisgreat : you can build a travel bass inspired in the same shape. The Riverhead Unicord guitar bass exist ! Look at this link : http://www.handen.us/riverhead/miriverhead.html anderekel and Xanthus : I´m excited too, I can´t wait the time to have this little baby finished ! But I´m 41 and I learned long time ago that if you want to run first you must learn to walk... and remember that this is my first DIY guitar. That is really cool. I like how your making all the components yourself. Thank you Daniel, you are a very talented boy with a great future in guitar building ! But let me correct you, I haven´t made all the compoments, I bought the neck from Guitar Fetish. Quote Link to comment Share on other sites More sharing options...
