I'll trade you for my Bad Monkey......it's a much better pedal than that "Old and Used" one ya got there.

God, I've got an old Ibanez Parametric EQ stomp-box from that same period. Looks just like it. In fact, come to think about it, it was the only reason that our sound system worked back in those days. We were poor! But that's another story....

Ah...eh...uh...buh....at those voltagelevels....only if the caps and chips are really crappy you can hear alot of difference, mostly it is just a matter of turning the knobs some....
Anyways some of the first ones had single OP-Amps, so they had to use two...they sound alittle flatter then your average TS....
But 4558s are mostly different in volume....not the most good sounding OP-Amp out there
But that is just personal preferences...

Re: Pics of the original 808 (big pics)
The components were pre-stuffed on to the PCB and then run over a wave of solder, component side up. It soldered everything in place in one shot. The solder would only stick to the solder pads but they'd still go through a cleanup and QC process to make sure everything checks out. There was no one person or two or three sitting there with a soldering iron putting the parts on the board.
In the QC process, those doing the checks would have a soldering station to replace any parts that didn't check out or were bad. But that was the extent of it pretty much.

Haha...anyways...only solder wire and perhaps a few pots, looking for errors, setting them up....hey wait...that is what I am already doing....
Hehe the solderpoints would defently be more pretty...but the PCB will get abit more expensive with the solderfilm....

I agree ... the 4558 is a very gritty-sounding op amp IMO. But people want them because that's what was in the holy 808 ...
Keep in mind Maxon didn't use one or another op amp because they sounded the best - they used them because they were the cheapest op amps that worked in this pedal.

Exactly. The TL072 is actually a lower noise and better sounding chip in the TS circuit but it's also more expensive than the 4558. In low voltage circuits, IMO, it's the tolerances that have more of an influence on the final sound rather than the type. Now, a film cap that actually passes the signal from point A to point B is the better option over ceramic caps in most cases. Shunting the signal to ground, anything will work there.

If you want a really nice op amp that sounds great in almost any pedal, the Burr Brown OPA2134PA is the Rolls Royce of op amps. They're typically around $5 each (compared to most op amps that cost less than a buck), but it's what you need if you want that "boutique", almost amp-like feel from a pedal.
I agree on the caps - metal film anywhere you have signal going towards the output will take a lot of grit out of the sound. Diodes and op amps are important, but caps will make or break a pedal.

I've got a few of those Burr Browns too. I was able to get a free sampling like 4 years ago when I started modding. They do sound nice. Had one in my SD-1 before it got modded to 808 specs. I may try it again since I've had some time with this one with the stock 4558 chip.

As time has passed on....the filtering, the clipcircuit, and a fairly consistant op-amp is the mainthing in drives....and floutique can go where the sun do not shine
