thanks guys!
do you know if the pots are lin. or log.?
so, the only thing missing is the value of the four litle smd caps...
and my schematic is ready!

Everytime when I see that Mr. Sean Lovepedal has achieved again to grab $ 200,-- of hard-earned money out of the bags of his customers I am totally entertained. It is really a remarkable skill to be able sell the same shit over and over and over again.
Anyway the most exciting part of the "Purple Plexi Saga" are the x-ray pictures. It is really funny to see that in a x-ray-picture a SMD-resistor can be recognized differently than a SMD-capacitor.
Many thanks to sandmann69 and minotaur87 for their effort.
Lovepedal Purple Plexi 800 schematic (audiopath only) ?
For historical and educational purposes compare it with the Krank Distortus Maximus schematic....
One last thing can be said, the rule:
"Goop is only an indication that there is nothing worth to be hided (except that the design may be "borrowed")"
has been proven again.

This I doubt very much.... Any tube-amp will sound good if standalone. The pedal standalone will never sound like at least a half Marshall - it will sound more like shit.The Lovepedal Purple Plexi 800 Overdrive pedal gives you two Marshall’s in one.
Leave away the amp - which really makes the sound - and it will sound like shit.This little guy makes any amp sound like either a Plexi or a cranked JCM800.
Does it sound now like piss or like shit - or both ?The Lovepedal Purple Plexi 800 sounds like a pissed off Marshall.

yep.
to me it looks that way too!
I don't like mr.lovepedal very much also,
but I do think he has some good ears
and at least he knows how to make shit money!
I'll have to try that pp800 first and than I'll say if it sound like shit or if it doesn't!
peace, love and bananas!

oh and to me the purple plexi 800 is just a refined Smashdrive,
as is the krank distortus maximus!
thanks to aron and tim!
oh and thanks to the mysterious person who invented" the electra distorsion in 1994, or whenever that was!
think you all know it refined under the cot50 name!
even more bananas for everyone!

Information
The relais appears to be a pulse-relais to reduce power consumption. One pulse switches the relais on, the next switches it off. Like in the Crowther Hotcake.
To produce the necessary pulses on one side, and keep the LED on at the other side, the PIC (12 F 684 from Microchip) is used.

ha ha ha .... kinda knew it was LM386 based from the clips....shit far from a Marshall amp.
Every freakin pedals seems to be a Marshall like
Most these mafakas never gone near a Marhall nor played one cranked....
I know people who are stuck with 4 or 5 of his 'eternity' and having hard time getting rid of it without losing money.
They usually come to me for theraphy ...thats all i can help with ..you know...a shoulder to cry on
AG ..ghandi and the xray fella .... thanks.

If the builder says it sounds like a Marshall, everyone jumps on the bandwagon and agrees.
The only builder who seems to have an ear and be able to actually mimic an amps characteristics somewhat is BJ IMO.

Minus the relay and the PIC, you could probably produce a pretty fair clone after experimenting with cap values. Although this circuit is similar to the Krank pedal (maximus distortus), it doesn't sound like it at all. The Krank pedal sounds like a typical harsh distortion pedal, while the PP800 more like an overdriven EL34-PT amp, very middy.analogguru wrote:The relais appears to be a pulse-relais to reduce power consumption.

the difference is the Krank has a 5088 before the LM386.
the PP is just a LM386.
anyone working on a vero board lay out?
i have started one yet someone else with more experience in these layouts can do a better job then my 'first time'

[quote="minatour87"]the difference is the Krank has a 5088 before the LM386.
The COT uses a 5088 tranny, maybe that's where the PP800 gets that nice round tone that makes it different from other disto boxes. Hope somebody comes up with a vero layout, I'd like to try a build for comparision. Hell, my COT clone turned out pretty good

upps, just noticed that I missed one 47uF cap, parallel to the 100n cap, from pin 6 to ground on my schematic.
the build so far sounds pretty promising...
I reduced the 100nF tone cap to 47nF witch gives a better range to the tone control.
all other caps are being the same as on the schematic.
a smaller input cap makes the tone to thin a bigger one makes it to muddy
and the 22nF after the 4K7 gives a low pass at 1540Hz .
I still have to try a smaller input cap, say 10nF, and a bigger cap, say 47nF, after the 4k7 resistor.
this will make the lows a bit more defined and gives a low pass at 720Hz which will make the sound even browner,
but it'll maybe be a little too much!

I suppose the small voltage drop across the protection diodes wouldn't have any significant effect on the sound (I think it's only about 0.2-0.3V for schottkys)....analogguru wrote:It´s an SMD-double diode connected in parallel - purpose is (only) for polarity protection.Fuzzer wrote:I don't get the two parallel Diodes coming from the V+, ¿What is the purpose of that?
