Hello huntest, It's the same as with an Orange Squeezer. Q1 is used as a variable resistor for the compressor. The bias totally depends on the JFET you use. For it to work properly as a variable resistor, it needs to be put into the linear region, meaning it needs to be barely "on" when there's...

Hey all, I managed to put "big" DC jack and audio jacks in 1590b, see pic below. I had to file the audio jack holes a bit down and use two extra washers on the inside of the audio jacks, though. But hey, it worked. I would attach PDF with drill template, but I can't seem to upload it. Forum...

Sure, but if every time you buy the same cap it's always the same amount over what's on the label, I won't blame it on tolerance anymore :)

From here: Link

I use the mini caps as well from time to time. My shop says that they're from Panasonic. My tester says ESR is quite low. But capacitance is usually a bit on the high side. Like, 2u2 is more like 2u6, 4u7 is more like 5u2. Although the last time I ordered the 50V variety and they had less...

Hi all, Schematic is over here: Link I wanted to try this out for quite some time. But I wanted to build it without the 8V regulator. Going from 9V to 8V seems a bit meh. The problem is, in my opinion, that the TLC2272 opamp is max rated for -8V to +8V, so in that sense the regulator makes...

Forgetting about the lid I measure a depth of 3.5cm. Pretty sure I got mine at retroamplis: https://www.retroamplis.com/Hammond-1590BBS-Diecast-aluminium-box They also link to the Hammond datasheet which contains more measurements. If you're in Europe that may be a good source.

Aionfx build doc says BB2 has not enough depths, he says it has 4mm less depth than BBS. I opened up my Straylight that I had built with aion's light shield. The BBS I used barely fits it. The highest points are the light shield and the power filtering cap. I would advise against BB2.

Hi Chuck, Sorry for the late question :) I'm just getting around to sweet bees and honey and whatnot. In the pregain section, R6 470k to ground. That was not in the first Mojito. There the 1uF went straight to ground. Why was R6 added? Was it because of the pot change from C25K to C50K+47K?

Not sure if PedalPCB has lugs 1 and 2 both connected to VB as there's no schematic in build doc (?). Use your multimeter to find out.

https://aionfx.com/app/files/docs/gladius_documentation.pdf aion says you could use 250kC and throw a 390k resistor from lug 1 to 3.

It looks very un-PedalPCB-like. But if it works...

Looks beautiful rwl :) I had noise on my build as well. It was even more prominent at 18V. I think I even posted about it here on the forum somewhere. My JFETs had a VP of ca. -1.5V. Once I replaced them with ones that had ca. -2.1V the noise went away.

Hello, I had the same question some time ago for Q1 of the Sabbath Distortion. So I made a little transistor switcher with an on-on DPDT. The Collectors are joined in the middle on the stripboard and always connected. The DPDT switches Emitter and Base. It worked fine.

Good to know, thanks. Yesterday evening I replaced the four OPA1678 opamps in my Median with four TL072. I wanted to see if with a simple opamp-change I could reproduce the clipping noise from the recording. I tried with two different humbucker guitars, also switched the buffer on the tuner in...
