I don't *know* that it matters where the buffer goes as the amp works properly with a buffered pedal in front of it but I would certainly put one between the volume pot and the amp at a minimum. I just put a buffer on either side of the volume pot to make sure the pot doesn't interfere with...

Ok, so I get a few stupid pedal ideas occasionally and things like this happen: - Direct (buffered) pass through to normal amp. - Larts Simple Cabsim to THCustoms Linedriver XLR - TPA3118 output. The volume knob only affects the TPA3118. The guitar signal is split using the vero layout I...

On the regulator? 330n between pins 1 + 2. 100n between 2 + 3. I used an IC buffer as I could use the 2 sections in a TL072. The current amp I'm building has a TL074 as a 3 way splitter, and a separate buffer. It splits to the (external) amp, cabsim and XLR driver, plus a send/return for...

It's a bit rough, does this help?

I got a couple done when they first started offering UV printing. Not bad, not great. The text is a bit on the blurry side, probably my efforts in Illustrator though.

So I measured the Marshall cab in the videos above at 15ohm, and I used 100Lolwhaats!? into it today. Again, plenty of volume on tap, not noisy in the slightest. Yeah, I hook the 24v feed up to pin1 of the regulator, and to the TPA3118 straight off that pin. Pin2 goes to ground, and Pin3...

Haven't tried one, don't see why not.

I've got that power amp lying around as well. It's not bad, maybe a bit noisier than the others, certainly a bit larger. I got around the 9v problem by including a 9v regulator and associated caps on the buffer board. On my latest effort, they're mounted directly on the power socket. I've...

Not really, but it would go like this: Guitar - buffer - buffer out to volume pot pin 1, pin 3 to ground, pin 2 to second buffer input, second buffer output to TPA3118. The IC buffers I've been building have worked fine. I haven't knowingly used a jfet buffer with it.

Dude, there's really nothing to these. Build a buffer on vero, run that to a pot, run that to another buffer vero, run that to the poweramp pcb. I don't even know if you need the 2nd buffer, but I put it there to get rid of any issues having a pot immediately before the pcb.

I've done a bit of that too. Usually to kids of friends who've started playing or have really started coming along.

If you have a look at my build reports in the Madbean forums, you'll see I put a fair bit of effort into the enclosures which probably helps. When I sell a personal or commision build I always tell the buyer that I will fix it free if anything pops up as long as they pay postage. PCB based...

Surprisingly, I don't have a lot of issues moving vero builds on, but I also have full disclosure in the marketplace ads. I'm not sure the pcb makes that much difference if you're doing high level artwork.

Nah, I've sold most of what I build but didn't use, something like 70 pedals all up. Gotten some decent guitars with all that.

Ok, here's my 3116 based build. The vero at the bottom is a dual buffer with the volume pot wired between them, with a 9v regulator and 330n flown off it.

Dead Chickens was written one night behind a police station when two mates and I were driving around town late at night. I had the guitar in the car and we were stopping around town and jamming. Having said that, it's all the one riff of F, G#, F#, G played in different positions on the neck...

I used to record local bands in my home studio 20 years ago or so. I'm building up my gear to start doing it again. The Lazy Gene Theory and Sorry stuff are my bands. The Halfcut demo was recorded at a local studio with my coverband at the time.

Ok. So, I picked up a secondhand [email protected] laptop supply and hooked up the new "150w" board and plugged it into a passive wedge (measuring 10ohm, 12inch speaker and horn of some sort) that I have and compared it to the little blue "60w" board. The results are thus: Big Red: - Turning the...

One of these arrived today too. Should be interesting as it says it has a preamp attached. It's probably 3 times the size of the previous board though. https://www.aliexpress.com/item/33017016220.html

Ok, I grabbed a 3116 a while ago, powered it off a secondhand laptop power supply and just had heaps of noise with it. Didn't work well at all. Anyway, I recently grabbed a 3118 and hooked it up to the same laptop PS. Running my Mooer Preamp Live into it gives it heaps of volume and I control...
