My current bass was built by Tom Clement - swamp ash fretless, Ipe fingerboard with Nordstrand reverse-P setup with J-pickup at the bridge. My own preamp (using 2n4416 jfets - got the idea to try them from Fdeck's bass rollloff box. With 18volts, they sound great).
I have built several Greenboy cabs (12 and 15s) - The crossovers have been modified to use a BMS tweeter that I like a lot.

Roland amp with speaker with DIY aluminium foil on loudspeaker cone for more stiffness and less resonances enhancing the sound a lot.

I figured I'd post some of my DIY stuff. Below is a single-ended EL95 amp with a single ECC8_ / 12A_7 in the preamp. Simple stuff. The tone knob is a bridged-T Framus-style mid control. It is followed by the Volume pot that has a 3-position bright switch tied to it. For the chassis, I used a Hammond 1590DD enclosure.
Something topologically similar to the previous amp I posted: input stage, Framus-style mid control, volume, bright switch, second stage, power valve. 6N2P (6Н2П) in the preamp and an EL91 in the output. This time I used a computer PSU enclosure for the chassis. Also, unlike the previous amp, it has about 6 dB of NFB. I'm still thinking about the right name for this baby.

Almost there - some alignment and the nut needs sorting but it's back to being playable.. I missed it compared to the strat and accoustic 😀
I finished a mini guitar with 17" scale. I tuned it like the last 4 strings of a guitar, with a capo at the 3rd fret. Good for playing some power chords.
Ha! I always wanted to do this by modding a 3/4 size guitar. A baritone uke is also tuned like this- the 4 higher pitched guitar strings. What kind of pickup did you use?
I could make one, but I “cheated” on the full sized guitar I made as I bought a Warmoth neck, and I doubt they make an ultra short scale, 4 string neck!

It's a 4 string cigar box pickup. it's a single coil with about 5k ohms.
I made the dogear cover using scraps of the pickguard sheet. Glued them together and sanded, rounding if off.
Several coats of black paint later and it looks nice and shiny.
I bought an ukulele neck, but in the end decided to make it a neck-through guitar. Forgot to remove some of the top to get an angle, though. So, now it has no neck angle, which kind of forces you to use a very thin bridge (made from a power supply heatsink).

Now you have me itching to make one. I have a buddy that is a big ACDC fan and he would love to have that as a wall hanger. I did give him a guitar and amp to hope he picks up playing, not much luck. But with four strings learning might not seem so intimidating.
Yesterday finished my DIY PP 6V6 amp with a tube FX loop.
The casing is of an old Dynacord.

I think these two are ready enough to be added to this thread 😀
Guitar you've already seen, the combo is its companion heavily modified Rob Robinette 2W EF80 amp with a JCM800/JTM45 front-end tube amp that's finally had its coverings put on. Its approximately 576Wx609Hx316D cab hides a G12M-65 16R.
This was before it had it's piping and corners etc put in:

It's not really a DIY project per se, but a restoration of a non-working, leftover-derelict Danelectro DM10 from 1964, that I bought for peanuts...

Now resurrected, it's a great sounding little amp ! 😎 😉

Thank you @Thomasha and @YashN ! 😎
I must confess that I took rather "favourable" pictures, because the frontface chrome is locally pitted. Here's below the condition of the DM10 when it came home - oh, I know that for a non-working unit, it could be even worse, cosmetically !
That said, transformers, tubes, cabinet assembly, speaker and its carton baffle were all dead, and many other parts were off, cut (R) or dry (C).

Hi everyone,
I primarily build & repair acoustic and electric guitars. Here is my latest build, of a model I've made for about ten years. While my acoustic guitars are usually traditional designs, I've always chafed at copying solidbody models. And this model (the Retro) is my response to music store owners telling me customers just want the same guitar products as 50 years ago, Strats, Teles, Les Pauls. Other luthiers told me I'd never make any money hand-carving necks, just buy them. They weren't wrong! But, I can't bring myself to make parts-casters. So, the Retro is meant to look familiar, a Fender pastiche. I've been told it resembles a Yamaha or Ibanez. Fair enough. However, it's got a 25.0" scale, 16-20" compound radius fretboard, 24 frets and my own offset 4-bolt neck joint that I'm rather proud of. And all the wiring is on the pickguard. Which makes contact around the cavity rim. There is brown tape covering some shielding to stop reflections from behind the pickups. Here you go:

Built a hybrid bass amp. Tube pre and ICEpower 700 power. Loved the sound of it, so decided to build 10 of them.
