salvaging old effects pedals for parts.
Is it silly to clip or remove out transistors/op amps from old effects for re-use? I have an old rat pedal that someone left and I wanted to use it for parts etc. I figre I can get out the jacks and knobs etc fairly easy, but the other stuff would be fun to experiment with. Just wondering if there is a way to remove things (trans,ops,resistors etc) from the circuit board and still be able to re-use them..I'm rather new to it all and saw that there was a de-soldering kit not sure that's the answer or if I could just clip them out..
any help or experience appreciated.

to me the most valuable part of the pedal is the enclosure - you can probably build a DI or a Reamp into that RAT case.
Most of the stuff in there is just worth pennies - you might just want to stick it on a shelf rather than scrapping it out right away.

certain pedals have valuble parts, like modulating pedals with bucket brigade chips. until recently no bbd chips were made and they were hard to come by, nos or used. even now with new production, being able to get your hands on old school bbd chips is akin to having old vacuum tubes.
as far as in a rat, the transistors aren't worth saving; new small signal transistors, even from good brands like fairchild, are usually less than ten cents each. the diodes, capacitors and resistors aren't worth saving either.
what is super valuble is the enclosure itself; even buying a nasty hammond box is going to run you several dollars, and then the time involved with drilling holes and trying to figure out a way to attach the circuitboard without it looking like shit (unless you're pete cornish and you're into the utilitarian sort of thing).
unless you're dealing with an old modulating pedal, don't worry about the discrete components. even in a tube amp, the only expensive components are the transformers; discrete components and tube sockets usually cost less than $50 for all but the most insanely complex amps.

put one of inverseroom's photosynths into it

I'd keep the circut board for parts. Individual components are cheap but can be a PITA to order sometimes. There is nothing wrong with re-using a part you already have as long as you don't damage the leads or use too much heat getting them out.
For getting them out I'd recommend a solder sucker like this, some #3 Solder Wick and a good pair of needle nose pliers.

thanks for all the replies!!..I ended up saving the enclosure and sanding it down and just kinda left everything, circiut wise..It was a mess inside lots of wires torn out..so it would have been a lot of work to get it to a point to sell it + missing a knob and various other stuff that would make it a hard sell. But I always loved the rat, so it was cool to see inside and follow how it was done. Seems to be an opamp lm308 and to get the 2n#'s from the transistors, etc. etc was really informative... saved the 1/4" jacks but really gonna use the enclosure it's really a good design for a box. anyone know where to buy that style enclosure?
thanks again,
Brian
