problem with Melos Echo Chamber

spy — Tue, 17 Nov 2009 21:13:32 GMT

Just found a non working Melos with 3 cartridges. They look like Dictaphone but I'm not sure as there's nothing written on them.

For some reason I don't have the wet signal. But the play head seems to work as I can heard the connection on the tape everytime it passes the head.
Also, I have the signal with the bias frequency on the record head. But how can I know if the record head work?

Does anyone have the same experience with an Echo Chamber? What do you suggest me to do?

Dark switch mod for 80's Ibanez delay? DDL 20, DML, (TS-10 series)

Elvisofnazareth — Tue, 17 Nov 2009 07:14:07 GMT

I love these delays. The best most transparent buffer I've ever heard regardless of price..... hence... My favorite delays. Can I put a cap across the volume or repeat pot like a Boss DD-2, DD-3 etc?

It's a wee bit bright, Id love a tone knob, but a switch would be cool.

The boss dd-2 has an awesome full frequency yet warm repeat, but the buffer blows with single coils into el 84 amps IMO.

THANKS!!!!

Rangemaster Treble Booster Tone control

Artemio_Cruz — Wed, 11 Nov 2009 23:34:55 GMT

Does anybody knows how to put some tone control in a Rangemaster Clone?
i read something about using a pot for mixing between 2 capacitors, where you would normally only use a 0.0047uF cap.
but i dont know what kind of pot im supposed to use, or how to wire it for that job...im a noob really...this is going to be the first pedal i build.
Maybe its better to use a switch???

thanks

Help and Schematics for Bell Electrolabs A.D.T. !!!

manuel-sevilla — Wed, 11 Nov 2009 11:24:07 GMT

Hi, I have a problem with my Bell ADT, is a kind of Phase Shifter and the overall modulation is distorted and noisy it seems to be related to the Voltage which controls the CD4006 or the CD4006 by itself.

Any suggestions ?

Does exist any chance to find schematics ?

Are the 20 years old Quartz Crystal Components subjected to Fail ?

and the CD4006 chip ?

Thanks in advance

EHX nano Clone

freakshow — Wed, 11 Nov 2009 01:45:32 GMT

Hi..

I have a nano clone from ehx, and everytime i try to connect to my powersupply it makes a shortcircuit so none of my other fx works until I unplug the nano clone

Are there any common problems with the nano clone, or am I just being unlucky ?

Mxr Dynacomp

BaaderMeinhof — Fri, 06 Nov 2009 09:16:24 GMT

Hi!
I recently got an old pcb from a MXR Dynacomp pedal.
Now im facing the delicate problem of putting it together with new pots, jacks and housing.
Problem is that the pics im so long collected dont give it all away, and reading schematics only confuses me.:confused:

Is there anyone with pics from the inside of an old dynacomp that shows how the wiring should go?

Thanks beforehand!!

A Place To Bury Strangers

Mister In — Wed, 04 Nov 2009 21:48:55 GMT

Can someone please tell me what effect pedals I should use to create more or less the sound of Oliver's guitar when he goes totally mental. It starts about 4:50.
I already have a Fuzz factory and a wah pedal

Boss DS2 pots

lowell — Wed, 04 Nov 2009 19:32:50 GMT

boss/roland say they don't seel these pots anymore. need a 50kL and 100kg mini pots. these are PCB mounted and are smaller than your standard 16mm mini pot. I don't know what "g" stands for w/ the 100k but a lin is probably ideal, however an audio is fine as backup. if anyone has these or know who does give a shout.

True bypass toggle switching in/out for stompboxes?

Mr. Twang — Sat, 31 Oct 2009 20:32:49 GMT

I'm a pedal steel player going back to stompboxes vs multi-FX rack units. I'd like a small strip of true-bypass toggle switches that I can clip to my steel's leg (or somehow have nearby) to simply bring fx in and out of my signal chain. With all fx out, my clean, pure sound must pass through unmolested.

First, is there already a commercial solution like this I can buy? I hope to avoid MIDI, so Voodoo Labs is, for now at least, out.

If not, who could i contact to have this built?

One more sub-question: ideally I want to have a rack sitting beside me with a couple of 1U rack items (tuner, preamp), and then behind those a drawer of stompboxes that pulls UP and locks into position, for easy knob tweaking. The little strip of toggle switches would connect to this custom vertical drawer. Anyone already making something like this? Who could custom craft this for me?

Thanks. PLEASE ANSWER, I so often get no responses on forums like this, it's odd.

BOSS DD-3(b) schematics

WhiteLyon — Sat, 31 Oct 2009 20:11:05 GMT

I am looking for DD-3b schematics, this would be the board with the surface mount parts. 3rd generation of the DD-3.
(Yeah sucks)
Does ANYONE have the schematics?
I get the 'check light" and "direct out" sound, no sound routed through the delay at the output.
Hoping the schems will help me trace to the problem, and that it is NOT that BOSS chip.

-Thanks!
