Quote from: phatt on July 19, 2023, 07:38:21 AMHi Joe,
        Sadly no as that hard drive died and took with it a lot of stuff. I do have some pcb pictures on CD somewhere but they are the early versions which were hand drawn and the early circuits are different.
It's not a hard circuit to layout as there are not many parts and only one chip.
Someone on another forum posted a perfboard layout of it, just let me know if you go in that direction and I'll post it.

I'll keep you posted.  I have a few projects in front of it, so it could be a few months or more.  Thanks!

Schematic is posted above and works still.;attach=3610
Quote from: Diary Of An Axeman on July 18, 2023, 03:20:55 AMI just fixed the the expression pedal for an old 1968-1969, Univibe .
Plugged it started playing it for a couple of weeks and the fuse blew out .
I did the old aluminum foil tick and found the unit still works, then I unplugged it and  took out the foil and put the unit away.
Would any of you techies out there know what kind of fuses that 1968-1969 Univibes used.
Any help would be greatly appreciated .

Looking at a schematic, I would hazard a guess that the power draw is somewhere in the 100ma range.  I would try a 250ma fuse and see what happens.  If it is too small, I wouldn't feel bad trying a 500ma (in case my guess of 100ma running load was off by a few factors).  I can't imagine it would need more than that though.

Curious, what size fuse did it have in it when it blew?
Great sound on that intro, I can see why you want to emulate this.  Honestly though, it shouldn't be too hard.  The Honey amp can sound like this with gain turned up about 1/4 to 1/3 (depending on what pickups are on your guitar).  I feel like this is yet another issue where tone stack in many preamp designs shared online are garbage.  A lot of times, tone stack before the heavy gain stages can fix your drive sound issues.

If you want to play with some stacks and adjust a circuit, check out TSC in the web:

I generally like a gentle sweep mid cut centered around 500hz as a good starting place.
Quote from: phatt on July 14, 2023, 05:46:40 AMThe Triumph Overdrive was impressive.
Smart move adding a decent tone control on a dirt pedal.
And designing one where the midrange actually works.
That's why I love my PhAbbtone so much as the mid control is very potent.
Humm, maybe he has been reading the forums and found my circuit.   ;D   Phil.

I'm actually planning on building a PhAbbtone at some point.  You don't happen to have a PCB layout available do you?
Brian Wampler has released his new take on the Bad Monkey overdrive - actually, two versions!  The Triumph Overdrive and the Phenom Distortion are 3 band EQ, toggle switch, crunch machines and apparently Josh Scott (JHS) loves them.

These pedals are listed for $99 USD.
TC Electronic has released three new pedals that they say mimic three of the most sought after tube amplifiers of the 1960's.

Here is the trio:

DC30 - Modeled after the 1965 Vox AC30 Top Boost

Combo Deluxe 65' - Modeled after the 1965 Fender Blackface Reverb Deluxe

JIMS 45 - Modeled after a 1965 Marshall JTM45

The DC30 and JIMS 45 come with additional boost footswitch while the Combo Deluxe 65' comes with a switchable reverb.  All three units have in, out, and DI with cab sim.

These pedals are currently retailing for $149 USD on most online merchant sites.

Glad to hear it!
Quote from: smadin on June 27, 2023, 06:12:59 PMGreat stuff, and a very pro looking build!

Paul does really great work, I was stoked when he was interested in the Honey amp.  Also, he is one of the main reasons I got into diy guitar electronics - his Firefly amp build actually, back in 2004.

Quote from: smadin on June 27, 2023, 06:12:26 PMLate to this party, but I figured I'd chime in that I also ended up finding I had to make my own LM386 model from the data sheet. I expect Paul's is more correct than mine, so I'm excited to compare them.

Certainly let us know what you find!
Hotone, known in these parts for their nano amp series mini heads, has released the Ampero Mini.  This is a small pedal-sized modeling amplifier with a touch screen interface and two stomp switches.  Using two 24 bit DSP chips, this little guy can utilize as many as 9 effects simultaneously.  It comes with 199 effects, 52 amps and 50 cabinets available. You can also change microphone type and position simulation.  Lastly, it includes 100 drum loops to use as backing, and has a built in stereo looper effect allowing for as much as 100 seconds of mono or 50 seconds of stereo loop!

These new little modeling platforms will be coming in 6 colors and selling for around $290 USD.  If you're into modeling amps and don't have the money for some of the fancy ones - this may be your next jam!

Thanks Paul, this should help!  I have to say that I'm surprised there isn't a solid LM386 model out there already though - it's such an old and popular chip, used in so many DIY projects.

Quote from: bill0287 on June 21, 2023, 09:42:19 PMHas anyone built this ("The Honey AMP") in LTSpice? I put it together and I am getting some really odd looking wave forms. Wondering if anyone else has seen this.

I've been meaning to share this for months and hadn't gotten around to it.  Paul Marossy has actually done just that!  Check out the fourth video here:
Fellow electronics enthusiast Paul Marossy (of fame) has done a 3 part series on The Honey well as a bonus fourth video.

Thanks for the honest thoughts on this Paul, great job on the videos as well!

Quote from: DrGonz78 on June 22, 2023, 09:58:48 AMI wouldn't use arctic silver for anything other than CPU's on a computer build. It says it has trace amounts of silver in it.

I 100% agree.  I only recommend plain thermal paste, no additives.  Or you can use silicone pads.
