effect boxes.

i was going to call this page "guitar effects", as most of the boxes are specifically designed for the electric guitar. however, there is no reason not to use them with other sound sources, which i frequently do. most of the things here are built from recycled components. rampant comsumerism and the increasing amount of pisspoor quality electronic goods means there is a ready supply of circuit boards lying around in containers and charity shops just waiting for people to come and make noisy things out of them.

please excuse the guitar samples, they aren't very inspired.

Effects loop box, with a buffer at the input and one at the return. Made specifically for a Dynacord tape delay I have in the guitar setup. The battery in this will last 50 years.

EH pulsar tremelo from Tonepad. It's... okay. Not the most amazing tremelo ever. Will probably put a better one in there one of these days. Made for Tuborg.

Couple of Roland Bee-baa clones. Made one a few years ago and some people heard it and so.


Big Muff clone for K. This thing sounds frikkin' great.

old delay pedal in a new box

made a while ago, hope it still works as it should

all the ins and outs you might need...

looks okay as well yeah i made it look like that.

even more metal boxes...

bass fuzz based on a well-known bass fuzzz... this was out the door before i had time to record any samples. shame because it sounds great. going to make another one soon. it had an LED but it affected the sound of the circuit so much i took it out. anyhow, it's one of those 'you'll know when it's on' effects box.

made for stig in aalborg.

dymo has come full circle with the retro look - woodgrain.

metal boxes...

commonsound panneur. i love this thing.

nothing yells 'homemade in the eighties' like red dymo.



made for neil young.


another gruntbox. made for mette darling.

a clone of roland's bee-baa. made for mikko

simple yet effective A/B/X box. three effects loops, A B and X... level pot for the loops. first switch chooses A or B. second turns on X loop. big fat rotary knob gives X alone, A or B through X, or feeds the whole lot back through itself for that 'damn that's painful' noise. plenty of lights to keep you interested. i'll get around to putting a signal flow diagram up at some point because that description was rubbish.

made for mikko (aka pol mod pol aka soviet subliminal seduction; gets around a bit, doesn't he?) for use in his wonderfully loud band double space. go listen to them now.

another roland funny cat clone. probably more popular now than when it first came out. pretty much the same as the one further down the page. no blinky lights, but you know when it's on.

made for ray j.

ladies and gentlemen...

... yeah whatever. based on an idea from mark hammer's site. bass fuzz, and a fine one too. keeps all of the bass while mixing in nice fuzzed overtones. this is a very poorly recorded and executed sample, but hopefully it'll give an idea of what this circuit can do.

i don't make many effects any more, but when søren asks for one, how can i say no?

duo distorter from the commonsound stable. fuzz and distortion in one box; simple yet effective. no samples as such here because i don't want to play guitar anymore, but in a pinch this box will pick up all kinds of waves floating around in the æther...

made for a bass player in copenhagen. he could be called frank. i know the rest of the band is.

the ever-strange jawari from tim escobedo's site, along with a bunch of other odd yet interesting circuits. this one seems to sound different every time i use it. here is a rotten sample, but it's possible to hear the buzzing-like quality that gives the machine it's name.

yes, the tin can is possibly the ugliest thing in the world. yes, the obvious irony of a pedal named after a part of a sitar photographed sitting on a sitar.

a copy of the dod 440 envelope filter, from generalguitargadgets. uses the hard to find vtl5c4/2 vactrol. if i was doing it again i would make a vactrol myself. would i make it again? you decide.

this pedal blends in well with the surrounding foliage, only exposing itself while attracting the opposite sex with a rather wooden mating dance. i think the box was originally used to contain salt. i could be wrong.


nothing special, just a crappy digital delay from the late eighties. the plastic case was falling to bits, so i fired it into a metal box. i think i might have messed with the trimmers inside to get a bit longer delay time out of it, which probably decreased the sound quality even more.



the commonsound atoner. a real nasty (read: cool) digital distortion. there's an lfo in there as well, and as with all commonsound devices pleanty of modifications available. most guitarists i know would run a mile from this thing, but i like it. not bad just wigging out on it's own. pretty crazy with synths, too.



a clone of the roland funny cat from geofex. funny is right, this is a strange machine. kind of fuzz-filter-almost-sample-and-hold type sound. given to howling as well. another of the 'irritating noise' effects i seem to enjoy so much. i think the case is some kind of sauce condiment, because there was an ugly ladle type thing with it. i wouldn't have it on my dinner table, i'll tell you.



a copy of the harmonic percolator, from home-wrecker.com. about twelve components. i like it. large output gain, very trebley and annoying sound.

the irony of using a coffee can heater as a case for something called a harmonic pecrolator is not entirely lost on me.



one day a friend of mine went out and bought hisself a big shiney new electric guitar. i felt he should have a pedal board to go with it. from left to right: autowah (i can't remember which) - commonsound tremelous lune - harmonic jerkulator from here (with my patented 'mystery switch') - orange squeezer compressor clone from tonepad and mxr noise gate clone, also from tonepad. why did i put a compressor so far down the line? because you live and learn, that's why.

so what's this mystery switch? simple. run a switch from a random point on the board. pull an unmarked ceramic disk capacitor from an ancient video machine. fit it to the other end of the switch, and run that to ground. gives a much more 'distorted' distortion, but effectivley halves the output signal. at certain settings will pick up spanish language radio, and considering i live in the north of denmark, this is indeed a mystery.



the lovely stereo panneur from commonsound. really smooth tremelo and panner, made from readily available parts in a container near you. but don't take my word for it, have a listen. and again. and another. and this is the last.

the box is a power supply unit for an ancient slot-car racing set. the transformer was able to creep around the floor by itself when fed 240 volts.


sexy, no? another panneur, made for a friend of mine who is a bit of a computer nerd. i couldn't build it into anything else, now could i?



a copy of the ampeg scrambler from the ggg site, cleverly disguised as some laundry. i've never heard a real scrambler pedal, but this is what this one sounds like. kind of fuzzy and with a little octave down. odd little thing.

now owned by søren.



bit of a pattern forming here, perhaps? a phaseur fleur from commonsound. another really smooth sound, with lots of mods, and a whole extra lfo thrown in for free. don't you love those guys? this clip does the machine little justice.


my guitar amplifier doesn't have any reverb. the solution: a standalone spring reverb box, the schematics for which can found at the ggg site. it sounds a little muddy, but the tank i'm using isn't the best. i've tried it with others, and it sounds much, er, cleaner. of course, this is the real reason to have a spring reverb box in front of you on stage...
