A semi-original from Xotic... some RAT similarities, but plenty of differences compared to your average RAT clone.

Hi all,

So I'm done with the pedal and it works fine now. As I haven't found anybody else posting a build report I thought I may just write my own.

I'm a fan of the small Solid Metal (AION makes one, too, they call it the Ember Distortion). So I really wanted the Pro version as well.

1. The Pro version gives you way more control.
2. The Pro version has lots of loops. A universal loop (always on when the pedal is on), a boost loop (only on when boost is on) and last but not least a bypass...

Hmm. Caline catalog is becoming quite puzzling one. These two here. Same f*king circuit. Paul Cochrane Timmy. 4558D, no switch for clipping, just the four 4148s for both. Highway Man has linear and log pots for bass/treble and Pure Sky has them at C50K. Pure Sky has designation screen prints under the components, but just by looking at the boards, component values and topology, i can safely say the circuits are identical.

Why on earth would anyone release two differently named pedals that have...

Hi guys, I am selling these tube amp pcbs:
1. Freeman BE100DLX based pcb (3mm thick pcb with 2 Oz copper) - 40$
2. S.I.R. 34/36 with plexi clean pcb (2mm thick pcb with 2 Oz copper) - 30$
3. Cameron CCV/Jose 50 based with simple clean pcb (2mm thick pcb with 2 Oz copper) - 30$
4. Fx loop - 8$
Flat shipping costs should be around 20$

Everything is verified and built few times
layout wirings are here

Cheers

Occasionally on ebay, now here the first time some guts:

Hi all, I have a tc electronics t2 (digital reverb). It’s generating its own noise, when I change the reverb settings I can hear that it has an influence on the noise. I have audio traced the signal to the ak4556 ad da ic. The signal gets to there then seems to have the noise on pin 8. I’m wondering if this means the ic has blown? I can’t find schematics unfortunately. Thanks all

This one has escaped the forums and layout sites. Switchable 4/6/10 stages, the feedback control is minimum at noon, one direction adds fb out of phase, the other in.
gut shot here:

I have a Smart People Factory Greenline overdrive and it stopped working.
When connected and engaged it gives a lot of noise.

On the PCB I see one red power wire loose (see attachements at place W4 on the PCB).

Any idea how I will be able to find a resource to solve the problem please?

It didn't seem like anyone had attempted this one aside from the photos in this thread , so here you go.

Just came out.

interested to see what TS-9 mods has been implemented?

Anyone had a chance to test it?

Seems it uses a PT2399 with Bontempo, according to the official website.

I hope it's alright if I ask here, I'm not a member of many forums. I asked this question on Talkbass as well.

I'm making a quad pickup, so I need to make 4 individual one string/magnet pickups. Should I still be aiming for a 7k-10k resistance range? Or does it differ if I'm using a smaller magnet. I did a test run and don't see me going past 4k rotations around the magnet before I run out of space. Some info:

Magnet length: 18 mm

Magnet diameter: 5 mm

Wire diameter: 0.0026 inches (42...

Amptweaker's first pedal design... lots of similarities to the Tight Metal/Tight Rock, but stripped down a bit. Less gain, no noise gate, a bit less tone shaping, no switches.

This one is pretty cool. A switchable silicon/germanium fuzz wrapped in Amptweaker's signature pre-drive bass cut and Muff-ish tone stack.

I have this one old photo of Barge Concepts VBjr. This was their base model variable blender, without phase inversion or expression pedal features.
Two Burr Brown OPA2134 opamps, mica capacitors, axial electrolytic and tantalum capacitors.

I got this pedal and LOVE it!!

Great fuzz face-ish sounds with two 2N404 transistors

Ok, reviving an old discussion . The tried and tested LDR's (NSL-7532) are EOL and/or you can find them for crazy amounts of money. Does anyone know of new (still in production) alternatives for Univibe LDR's?

I found that there are still 9203 LDR and NSL-7530, but I do not know their production status or if they are EOL.

To be short. Do you know and tested still in production LDR's that make a lush Univibe (using a lamp, not LED like, Neovibe, Habinger x, etc.)?
