* Got a chance to swap some capacitors and the tube, in my old 60's Sencore Tube Tester

Great tool to have around

* Another HGE Contraptions JHS Morning Glory clone
(123rd pedal built!)

* HGE Contraptions Catalinbread SFT II clone, with the stoner switch. Very cool QOTSA sounds from this mean od/fuzz thing. I used Motorola MPF4393 transistors as per the original.
(124th pedal built)

Vid sample

Important later edit:

In the meantime I discovered a general error that existed for this schematic on the web, and corrected it for the owner. Now the Gate from the Q1 position FET is seeing a stable voltage. This is totally wrong online and I will do my best to alert anyone who does this to correct this. Basically moved one leg of the 470K resistor at the input 2 rows down(at the other side of the 100nF resistor).

* HGE Contraptions Boss CE-2 Analog Chorus Clone (2nd version)

Built this for bass, but it's just slightly different from the guitar one. The owner didn't want the original blend, so I built it in the regular version.

I used shielded wires this time for all the INs and OUTs.

125th pedal built

 

Video sample and pictures:

* Swapped 2 faulty pots in a Rocktron Gainiac 1

* Retubed/biased/resoldered all the tube sockets on a Brunetti Pirata 141

A very cool amp with a unique Valve Mix option. You can combine EL34 and 6L6, or choose between the two.

* Did some work on a Squier Classic Vibe 50's Strat:

-guitar is a leftie but the owner is right handed, and he wanted to use it right handed, so I swapped the nut for a right handed one, and adjusted everything accordingly;

-the usual setup with the trem made floating;

-gave the fretwire some shine;

-electronics were good stock;

IMG_20190301_123854.jpgIMG_20190301_123900.jpgIMG_20190301_123808.jpg IMG_20190301_123911.jpgIMG_20190301_123800.jpgIMG_20190301_123804.jpgIMG_20190301_124142.jpgIMG_20190301_121731.jpgIMG_20190301_102240.jpgIMG_20190301_102255.jpgIMG_20190301_102308.jpgIMG_20190222_202933.jpgIMG_20190222_190441.jpg

 

* Some work on a beat up Fender 70's US Musicmaster Bass:

-had the neck refretted/cleaned/lacquered at a local luthier in my country, because it had extended fretwire damage (thank you very much Mr. @EugenRo2001 );

-did a full setup/derusted/replaced all screws/cleaned everything (this was a very very messy and unplayable instrument prior to everything);

-had to buy a tuner key to match the other ones (very hard to find, but I had some luck in the US)

-the wiring was a mess, so I redid it with appropriate pots and also redid the aluminum foil on the pickguard back, and also repalced the pickup wires with cloth ones;

Sounds great now and plays very good for such an old forgotten bass. I quite enjoyed it :)

Some after and before pics, and also a video of me testing it:

Epiphone LP Standard came in for some work:

-general setup + nut slots filed
-tuners had to be tightened
-fretwire made smoother to the touch and shined
-electro parts cleaned (stock wiring was decent enough)

* Repaired a Ferrite EQ
 
IMG_20190324_123344.jpgIMG_20190322_160959.jpgIMG_20190322_161004.jpg
 
 

* A Carl Martin Octaswitch came in with some issues on the DC Jack.

I replaced it with a new one, and also tightened all the switches/jacks + electro cleaned.

The buffer part is not working when it is on (no sound), but the owner needs it and it will come back at a later point to investigate. This would also take up a lot of time for finding the fault as the PCB is quite big

IMG_20190327_200024.jpgIMG_20190327_195353.jpgIMG_20190327_202846.jpgIMG_20190327_190752.jpgIMG_20190327_190951.jpg

 

* Fixed a Bugera V22 Infinium

A tube failed (I measured it with my Sencore TC136 Tube Tester and it had 2 shorts, and everything was out of spec), and had completely desoldered one of the screen grid resistors right off the PCB, leaving it rattling around in the amp!

I replaced both, and to be easier for future service if it is needed, I mounted them on the other side, so that these are easily desoldered  (not needing to take out the whole PCB)

IMG_20190329_142817.jpgIMG_20190329_140952.jpg

 

 

* Fixed some Pioneer SE-MJ722T-W headphones

Had some trouble finding a flat wire, but after a long wait, it finally came in and I could replace it.

The old one was literally eaten by a dog haha

* Setup on an Ibanez S520EX + fretwire made shiny and slippery again, tarnished screws were cleaned and some were repainted

IMG_20190412_143602.jpgIMG_20190412_143610.jpgIMG_20190412_143614.jpgIMG_20190412_144149.jpgIMG_20190412_144611.jpgIMG_20190412_144251.jpgIMG_20190412_144839.jpgIMG_20190412_143627.jpgIMG_20190412_143659.jpgIMG_20190412_143847.jpg

 

* Squier Stratocaster Pro Tone Series setup

IMG_20190412_173402.jpgIMG_20190413_140606.jpgIMG_20190413_140632.jpgIMG_20190413_141424.jpgIMG_20190413_140711.jpgIMG_20190413_140947_1.jpgIMG_20190413_141219.jpgIMG_20190413_140757.jpg

 

* One coil from the bridge humbucker on this Epiphone LP Standard Pro was faulty. I tried to repair it but the coil was broken in two places(because it had a manufacturing error with some slack on the winding,it got caught in the upper rim in the wax, and when someone removed the cover, the coil broke).

So happens that I had an Ibanez premium humbucker with just one coil working also, and I used this good coil with the other LP coil and made one humbucker!It sounds great and it's even better now,because this new coil has much more output than the old one, and gives a nice bite to the guitar now. Very cool!Glad I could fix it in such a short time without ordering another humbucker which would of meant additional cost

After:

* Checked and also changed the jack on a pair of AKG K240 headphones

* A Stagg G300 came in for a setup.

I also polished the fretwire, and checked the electro part, and changed all the tuners because the old ones were busted and poorer quality.

A very nice and playable guitar now

* HGE Contraptions Wampler Triple Wreck Clone without the Cream part (I never cared for it). The enclosure was done like that by the owner. 3rd Triple Wreck built, and the 128th pedal built.
This and the BE-OD are my fav Od/Distortion in a box pedals. I'll try and make a video later this week.  @octakhan

IMG_20190503_125554.jpgIMG_20190503_130356.jpgIMG_20190503_130421.jpg

 

* Fixed an Apex 430 Microphone.
It had intermittence issues, and I found numerous cracked solder joints and redid them.

Did not get to test this, so it will probably come back if there are additional issues.

* Started a more ambitious pedal project for someone who already has 4 of my pedals ( @Mr Vintage )

HGE Contraptions Custom 6in1 Pedal:
Cornish Buffer -> Keeley 4 Knob Comp -> Maxon OD820 -> Mxr Phase 90 -> Madbean Leviathan Delay -> Cornish Buffer

* Yamaha John Patitucci signature setup and fretwire shined. I also changed the input jack socket

A very cool bass

* Repaired a Mackie Big Knob Studio audio interface

The USB connector was completely busted and broken. I also added some missing screws from the XLR sockets.
