didn’t expect any noticeable difference between them. but there are actually. Sennheiser 1/8″ to 1/4″ phone plug adapter sounds way better
Hi community, since a long time I’m pondering about two topics that interest me. Stones / rocks and their industrial processing. If I want to cut rocks or slice stones in small pieces I have to use large machines, the energy consumption of such stone cutting machine is way too high for somebody who would just start to cut / slice rock. So, my question is: Do you have any ideas, thoughts or know about eco-friendly techologies which are energy efficient for cutting rocks into small slices? Every input regarding this topic is welcome.
Not sure what I’m going to do with this speaker while I don’t have any SF or BF fender. I remember my friends older than me loved it when I was a kid. even I still remember how the sound was. I saw the same speaker with gray and orange frames. this D120F came from 70’s silver face twin reverb and it’s orange. and it still has the original cone
a member here recommended me 5751 for tweed deluxe v1 socket. and I’m impressed with this setup. I grabbed this off ebay for $32 even the kind seller sent me an extra GE 5751.
I’d say it’s way better than stock 12ay7 and 12at7 on v1.
and 5751 on 5F1 reduces the output volume a bit. but still a good sounding tube
did a simple job for a friend. he has some extra 50’s Jensen speakers and wanted to use them with this GT40 amp.
he told me GT40 has mono and stereo output mode. so, we decided to leave one of the 6.5″ speakers as it was. then put a long thread 1/4 jack on the other output.
the only place I found for the internal/external switch was the inside of the bass reflex vent on the back. the back panel itself is too thick to attach the switch.
Researchers at the Massachusetts Institute of Technology (MIT) and Harvard Medical School have teamed to develop a novel tattoo ink that can show your body’s health changes.
The novel ink consists of biosensors that react to changes in the tissue fluid and make the skin an “interactive display”. So far, researchers have investigated four biosensors that respond to three types of body information, changing their colors.
As the pH-value increases, the color changes from violet to pink, an increasing sodium content is seen as a bright green under UV light, and blue becomes brown when the glucose level increases.
This animation from a video of the researchers shows how such a tattoo might look like:
Especially for diabetics, a tattoo with ink that reacts to an altered glucose level could be useful. They have to prick their finger with a small needle if they want to measure their blood sugar level – usually several times a day. This procedure can be painful in the long run and can lead to small scars.

I just tried this from a hunch while I barely understand electric circuits.
Bum fuzz was made after B&M fuzz. it came from Tonebender Jumbo, and Jumbo came from Big muff. and they are not far from Tonebender MK3. it means this pedal would work with Germanium transistors.
Sola Sound make 3 different versions of Bum Fuzz units with BC184, BC549C, and ZTX109. BC184 and ZTX109 versions look same to each other except ZTX109 version comes with better and older electric components. BC549C comes with cheap ass version. and, it has 3 of different resistors and 2 of electrolytic capacitors at least. I replaced them with 33k, 100, and 100k resistors an 2 of 0.1uf fixed caps.
OC139, OC140, OC141 are NPN germanium transistors for computers (yes, the computer) from late 60’s. They are period correct for late 60’s and early 70’s fuzz I guess. and, have the similar Hfe range as well. most of them I found on ebay.co.uk had 100 to 200 Hfe range. some are less than 100, and some of them are over 200.
It’s the shop I found ZTX109 and OC139 transistors
And, this pedal sounds great with OC139. I don’t see any reason to try a different setup anymore. this modified Germanium Bum fuzz unit has overdrive to medium or leather high gain fuzz range now. somewhat sounds like MK2 and feels like MK3.
It was like this a couple of months ago
