This metal box sells for under £30 and has the same old EQ bands as the Behringer and Boss boxes.

The red dots on the sliders do not light up.
Test points underneath:

Sliders are on a daughter-board that makes access to half the circuit tricky.

The same board is used for the guitar version, active frequency bands listed for both.

The op-amp used is the 4560. I'm sure there are lower-noise devices...jack sockets on boards.

Input/output, flip-flop for soft switching, etc., I guess are...

I'm repairing a whammy IV that has a dead midi port.

Does anyone have a schematic?

Thanks.

Variation of on the dynacomp/ross compressor with output buffer...

guts and schematic. With the information before, one should be able to rehouse this awesome compressor into a 1590B. Why pay $200 for a boutique clone? :horsey:

Got this for repair...

Anyone here have a schematic for the DOD 585-A Analog Delay pedal or some gutshots?

I'm trying to fix one and I am finding differences between the board and the 585 schematic that I have. As well I'm not sure if some of the wire jumpers and changes were factory made in the A revision, or if the changes are the result of someone modifying the pedal.

Any help greatly appreciated

Hi

I'm new here, looking for help, I have a barber Smallfry, which I love, out of production for a while now, it sounds warm and creamy, ala Robben Ford. Thing is, I'd like to have more drive, it is basically an overdrive, which sounds great with humbuckers but quite thin with single coils, would anyone happen to know what components to change in order to up the drive? This pedfal clips in 3 different ways, and has a switch for that, according to the manual: Stock, simulated asymmetric and...

Solid Metal by Damage Control.

someone gave this to me to have a look at as it's not bypassing properly. thought the forum might appreciate the gut shots as it's not here as far as i can see.

unmarked pot measures 10K, all other important bits pretty clearly marked in photo. dusty 4tab black box (am guessing vactrol) marked CO5M0 357MT.

if there are any unmarked bits you want more info about, let me know.

am guessing it's a clone of something well known that will be obvious to the seasoned eyes here.

enjoy.

Hi there
I have inherited, what appears to be an early Dunlop GCB-95.
I say early as it doesn't have the sockets attached to the board.
The case (which weighs an absolute ton compared to my Jen Wah) has a socket hole for a PSU input but the previous owner seemingly removed this...?
I wish to restore this socket to run from my T-Rex Power Pump Junior but don't have a clue where to attach the two wires.
I'm NOT an electronics guy (though I have performed various mods on valve amps and pedals with...

Hello

I've got one of these on my bench for a small repair.
It's a very interesting stereo chorus capable of smooth and very subtle effects, but also weird pitch modulations and seasick generator. It reminds me the TC SCF because they both have a modern clean overall sound, but the Elita is more dirty in a good way.
It is based on the KA5286P2 chipset, as usual in modern russian pedals the wiring is neat and clean.
It runs on +15V positive tip minijack 3.5mm, not pedalboard friendly; but I've...

Hi all,

Just completed some mods on this baby! It is called a Phatbass although the 'bass' addition was not that great! It still functions better on guitar then on bass.

So here's the schematic:

Maybe I create a theme in a wrong section.

My friend gave my this pedal. With problem
Booster is not working. When boost ON, (Q13 close) sound only present in left position. Turned right sound makes durty, not like guitar, volume doesn't change.
Please Help!

Thanks!

P.S. Sorry for my English, im from Ukraine.

I have a DOD FX69B Grunge pedal. I bought it used. I took the back off to see if any mods had been done to it and found that two wires had been clipped off of the white terminal block at the bottom of the PCB. The wires are brown and white. I was wondering where these wires were connected. Anybody have one they could open up and check? I'd greatly appreciate it.

TIA,

Hello fellow,

Original instructions and schematic:

I was for a few days to implement the BYOC Phaser (Phaser Royal), and this works very well.

My martyrdom surrounded himself in the inclusion of an LED to show the LFO oscillation speed.

A simple LED and resistor would suffice, but the LED does not turn off when the wave was approaching zero, low oscillation hardly noticed the oscillation through the LED.

Well, I managed to resolve after a few days and some workarounds, then tracking...

Hello everyone,

Can someone take a picture of the copperside from a Nobels CO-2 compressor - sustainer or a nobels overdrive / distortion pedal?
I bought one recently but the copper pads are fried around the switch.

Thanks in Advance!

Hello

these have probably been posted before, i bought this and it wasnt working properly (only made sound with the octave switch in the down position) i opened it up to see if something obvious was wrong with it, but couldnt see anything... and now it doesnt make sound at all!

Also im curious - does anyone know how to tighten the inside tip touching bit of a sealed jack socket? when working the output jack was a bit slippy .

anyway... some circuit shots of the danelectro french toast octave...

i recently purchased a rocktron tri-wah pedal for about $50 used, its in a nice metal housing and has 3 selectable modes. i would like to make it true bypass and maybe change some values for better tone. anyone have suggestions (i will try to attach the schematic)..thanks.
