Re: Wampler Pantheon [traced]

While some will say this is a clone type of the BluesBreaker pedal.... I would like to think that Brian went steps further .... I have one of these in the shop for a bit and took a dive under the hood. First thing I noticed is that the board was labeled "Paragon 02-2017b" - a working title? IMG_763...

I bet the tone control is drawn wrong too and should look like one from a tube-screamer - please verify. hi, I thougt about the circuit differences and made a circuit simulation. The shown tone circuity has indeed no effect. You are right regardíng the screamer tone circuity. Thanks that you took a...

Hey guys, here I transcripted the layout, correct please if you see something wrong, cause I'm gonna prepare the PCBs tomorrow :D [ Image ] Looks right, but I *think* r16 and r7 were 1k resistors, not 10k. I thought we had used independent voltage dividers as well, but maybe not on this version. It...

Re: Boss MT-2 Metal Zone mod for clean EQ/boost pedal

well, whatev's :)
The mods were posted as fun, not as a be-all end all. The mt-2 isn't that complicated, it's a basic analog distortion pedal with a fun EQ. Just bypass the distortion, making it a buffer before the eq.

I tried 3 different LM386N-1s and a bunch of MPSA18 and BC550c. All about the same noise level.

Has anyone else experienced this noise with the fuzz engaged? Is it normal?
Nope, not normal

Re: Wampler Velvet Fuzz [traced]

I have built this with the plexi/fuzz switch option. The Plexi by itself sounds killer, but when either fuzz is engaged there is a noticeable amount of hiss induced. The tight fuzz is the worse of the two. Is this added noise "normal"? I've tried 3 LM386N-1, all about the same amount of noise. I'm ...

Re: Help With a BD-2 Mod?

I've searched high and low on here and I can't find an answer to my question... so here goes: I decided to mod an BD-2 using Brian Wampler's old book on modding pedals. For the Brent Mason mod and others C10 is listed TWICE. :scratch: As far as I can tell it's not C100 or C101, which are the HP/LP ...

Hi, When it's written "remove the caps'', do i have to let a "jump" or do i have to wire ? A kind of replacing a capacitor by a wire ?

Re: Wampler - Plextortion [traced]

Someone managed to unravel the scheme? no big deal,put a buffer in front of a Guvnor,clipping diodes are clear red leds,same 3 band eq,plus an output gain stage recovery and a low pass filter for vintage/modern,you're done. My 2 cents:my least favorite sounding guvnor style pedal,i'd take any other...

Re: Wampler style voltage divider ?

I suspect that it's habit or layout that drives this one. References have some very peculiar issues, and using multiples has some virtues, but the differences are subtle. You can trick yourself without meaning to. It gets difficult to figure out what is what sometimes. For instance, in this circuit...

I'm sure it'll work as the schematic posted has it, it's just not the faux spring reverb circuit from us. You need a variable low pass filter on there that's inverting.
