Probably the schematic is still based on six transistors. At this point I'm really curious about the switches. «#34 Toggle Switch: This switch will allow you to achieve the famous MOD #34, a modification that can be made in a 1959SLP or JCM800 amp and that has been the main tone of one of our...

Monolithic Dual JFETs? I didn't know them, but I think you could be right. So three transistors, but actually those are six. The trimpots are missing, but maybe those kind of transistors are more accurate, or if it possible, matched or selected to work ok with a specific resistor value. The...

Hello, I have a question about the PAL800, the JCM800 Emulator, the PedalPCB version is the M800: http://www.pedalpcb.com/docs/M800.pdf The schematic is a jfet version of a JCM800 preamp: six transistors with five trimpots. That was the old version of the PAL800. There's a V3 version, now, that...

Hello. I tried some mods to make it a clean pedal, but the thing is not been a success, and I gave up for the moment. So, as I wanted to do, I finish my board (stripboard layout) to make the Malachite schematic. Today I soldered the last parts I tested, and like my last test it worked ok, I...

Original and replica pedals sounds pretty the same. But I'm wondering why the setting of the knobs are so different.

If you want something different and versatile you could try the Malachite. It sounds to me very amplike, very nice mild crunch. And it has a three band eq that the other ones you built don't have.

Hello, I'm back on it, finally. I built the circuit of the Malachite / G2 stock and I like it. It's a nice overdrive. I have some parts on socket so I made those experiments to get a clean preamp. I replaced R8 22k with a 10k. The effect is considerable: this makes a noticeable volume and high...

I couldn't order material in these last months, so I have a bunch of complete board, incomplete board and just partial parts in the bag for some pedals. Speaker Cranker and Smash Drive almost done. I'm working on a Splitter Blend with extra features. I'm working on a Mockman 2.0. I have to...

Me, too. Is this the same circuit of the Wampler Dracarys? I have a thread about it, I was looking for some clue about the schematic.

I built the Rotten Corpse version (on veroboard). It sounds a bit harsh to my hear. You can try to add a low pass filter, it worked fine to me.

I'm watching this, now: I can compare it just with my clone. I hear that the gain doesn't get down like my Triple Wreck. The TW becomes muddy at low gain. The Dracarys remain even more aggressive at low gain setting, I guess. The treble in the Dracarys are more tamed, I guess, and of course it...

Hello. Do somebody know what is the Wampler Dracarys? Somebody assumed that the Dracarys is a modified Triple Wreck but I can't find any video comparison of the Triple Wreck and the Dracarys, at least to hear both in the same video. I know that the Dracarys has tighter low end than the Triple...

I thought that the best part in the OCD was the mosfet clipping. But, I have to say I didn't try silicon diodes when I built my OCD.

I'm not sure how much we can trust on it, but: https://www.thegearpage.net/board/index.php?threads/keeley-d-m-drive.1820897/post-24126962 «Spoke with someone at Keeley and confirmed that the Drive side has its origins in the OCD with several modification and the Boost side is rooted in the Klon...

I knew it was based on OCD and Klon. But I didn't see the gutshot,

It seems very nice. Do you want to share the schematic? Just if you want. ;)

Torgoslayer is right! I don't know well these two pedals, but the Devi Ever Electric Play are two pedals in one: http://www.effectsdatabase.com/model/deviever/cymru/electricplay, The Electric Brown and Lets Play. I guess the switch exclude the LP, but I can't be sure. If you like stripboard...

Hi, I'm not sure if there's a mistake in your circuit, but the loud issue, I guess, can be solved using a log pot instead a linear pot. You did it, but you changed even the value, from 50k to 250k, I don't know how much difference can do change the value. I didn't understand if you changed some...

I guess it's been a while we still don't have the XB-MB Boost schematic. I don't really need it, but I'd like to see it if you will. Thought I guess I can't imagine what's the Mid pot is. Thanks! :cool:

I got some squeal/whine issue with some fuzz circuit, still didn't solve. My old Boss PSU has always worked fine, but sometime I got this issue, With a 47R or a 1N5817 in line to the 9v I always solved the problem. But I built the circuits of a Woolly Mammoth and a Ultimate Octave (a modded...
