Another part should be modification: on ebay you can buy really cheap pedals. For example this week I bought a Ken-Multi/monarch Distortion for Eur 8,50 plus shipment. This boxes are not so bad. For example the PSK SDS-2, SDS-3 or SDS-5 (seems to be now the roque SDS-5 can be easily be modified to be a Rat. They put in this unit since years a 470 Ohm instead of the 47 Ohm resistor in the...
Correction. There is a 1k resistor from pin 5 (heater) to the 470k grid pullup resistor. So it isn't exactly the same, the 1k resistor is on the tube board (probably a sub for the 2.2k heater resistor, there are only 4 wires to the tube board). And my digital camera batteries are taking forever to charge.
SMT, but the component values are on the silkscreen.
The reject bin tube barely amplified, I had to replace it.
Just got the mod for the VT911 in the mail the other day. What a great scam these guys are running. You get 2 capacitors and 2 resistors, a Bitmo decal and an instruction sheet - about 50c worth of stuff for $20 US. By the time I'd paid for postage and the rest it cost $40 Australian. Anyway, I guess I paid for someone else's expertise - or my own lack thereof. I think I need to start reselling electronic components to guitar players.
I must admit though that the mod is a huge improvement over...
The Sonicake Volwah is an extremely affordable, real estate saver of a pedal, with volume and cry baby wah style combined into one tiny enclosure. It has two LEDs which seem to be RGB to me since they are green when Volume mode is active, and red when Wah is active.
Without questioning it's build or sound quality, my main issue with it is that the LEDs are UNDERNEATH the expression surface. This pedal really small so you can't see it entirely when it's under your foot and that's just part of...
I recently bought a Brown Distortion pedal by Mosky, because I'd heard it was a clone of the Wample Pinnacle.
It does sound good, but I'm experiencing what I believe is the infamous sag issue, but that's not the point of this post.
Anyway I've opened it up and traced the components. It is indeeed a close copy of the Pinnacle, at least compared to the schematic for it that I found on this forum.
The layout is different and there are a few different values. It is well made and with...
Has anyone modded the GDI-21?
I think I'd like to add a mid control to it, True bypass, and fix the darn squealies the thing makes with EMG pickups.
I'm also considering using them as building blocks to build a 4 channel preamp.
I have a Tech 21 tri-ac that I love, and the Behringer GMX amp as a backup.
The gmx looks like two GDI-21 with a different input configuration on the jack.
The GDI just sounds like crap against the other two.
Anybody ever mod an Arion Stereo Flanger? I could use any help I can get as all I can do is switch out parts, no real technical knowledge at this point. But I do like to take the stuff apart and put it back together, especially when it sounds so much better after changing a couple of parts. Anyway if anybody can give me some info thanks very much.
he function of D14-15 is pretty unclear to me, they don't add clipping nor affect the volume or tone, so I just keep them in. D11-12 have the biggest effect on the distortion, you really hear the difference when you use a LED or silicon/germanium diode here. D8-9 have the least effect, I mean, you do hear the difference, but it doesn't really change the overall tone, the effect blends in with D11-12.
I use a Germanium in D8, D9 is standard, D11 standard and D12 a 5mm red Led. This gives me an...
Hey all, I'm new to the modding game and slowly getting my head around schematics and such. As I understand it, the DF-2 pretty much has the same distortion circuit as the DS-1, though given it's fitted alongside the feedbacker, the schematic to an amature is decidedly more difficult to figure out. Now, following it I can kind of see how the distortion's the same, but I'm not so sure on how to perform DS-1 mods on it without possibly bricking the whole thing.
I've bought a cheap Belcat PHS-605 Phaser and it arrived some days ago. The build quality and sound is okay for 34 bucks, A bit too much flux is the only thing to complain about. I really dig the sweet graphic design and clear knobs.
It didn't work at first so I opened the housing and found a trim pot. It turned out that it wasn't set by the manufacturer at all.
I setted it by ear. A little tricky, but it worked for me. I used the Rate in the middle and depth all the way up...
I´m not quite sure if a 49€-pedal qualifies as cheap, but to me it does.
I acquired a Nobels PRE-1 for 30€ used and I figured I´d do a few things to it. It´s built rather sturdy.
As a starter: how do I change the frequencies of the treble and bass bands.
Can anyone explain what the circuit is called and how to calculate the values for different frequencies? The manual states 25Hz and 10kHz.
What type of EQ is this anyway? Shelving?
Forget about Teese wahs and all the bullshit about specially manufactured parts etc., here is how to make any standard cry baby wah sound much better. :wink:
First - replace all those shitty little blue capacitors with some better quality ones - I used those little grey MKT film types, but you could use xicon film for still better results. (They are 10n x 2, and 220n x 2).
Second - find the 4.7uf electrolytic capacitor and it's 82k ohm bypass resistor - replace them with a 3.3uf BP paralleled...
I bought this cheap house brick of a pedal about a year ago and i love the tones you get out of it but theres a huge volume drop when its engaged , so i was wondering if i could remedy this some how , all the resistors look like tiny surface mounted ones to me but i was thinking maybe i could add a small boost circuit as theres plenty of room inside the casing ,
I really new to pedal modding so im just looking for feedback/ideas on the subject , i can add photos if you like.
Here's another cheap flanger to monkey with. Through hole construction, attractive mauve plastic potato bug enclosure, 3 trimmers on the board, what's not to love for a $20 flanger?
Obviously I'm going to play with the trimmers. DUH. But what else can we do with this thing? What is it based on?
NOTE:
The board is pretty brittle. I chipped off a part of it (you can see in the photos) and will have to scrape away the green and run jumper wire. This happened because those knobs are ON...
I have a Daphon E20CH Chorus pedal which came to me in a broken state, though was an easy fix, and now I'm wondering if I can give it some improvements to make it as quiet as possible and maximise its performance.
It's using the MN3207/MN3102 BBD pair, plus there's a MC4558 and 022D JRC (an 8-pin amp chip). There's 8-10 X C1815 transistors. Most of the caps are green polys - plus several cheap-brand electrolytics. The resistors all appear to be carbon film, the PCB is...
Just found one of these for very cheap so I gave it a go, also to understand why everybody talks bad about this one.
Actually I like it, it has its own caracter and voicing (kind of a woody tone). But I understand why people may complain about the fizziness. Strange noboy yet opened a thread about this one, so here we go!
Here's what I did to mine, to remove the fix and add a bit more overall body to the pedal:
C9 47n
C10 2n7
C7 3n3
R21 47k
R73 Jumper
C40 10n
R49 1k8
C18 1uF
Generally I'm impressed with the cheap TC Electronics line of basic pedals: they cover the basics, are extremely affordable and are built like a tank. With the Eyemaster HM-2 clone however, they decided (in all their wisdom) to only make the Gain and Level pots available, which makes it less than useless. So I set out to mod them to make them more useful. I propose two possible mods:
* Add a HI pot, with a focused range around the max, or:
* Move the Gain and Level inside, and bring...
There are all kinds of DS-1 mods out there and some are better than others. I've tried several and replaced all caps, the IC, etc...but it always falls short because of the overcompressed sound that plagues Boss distortion and OD pedals. I hit my low E string to hear the bass and when the stock DS-1 is engaged it cuts off so much low end it is ridiculous! This is why an old MIJ DS-1 is surprising because it is very open and warm. The reason is the diodes. The 1S2476 diodes clip at higher...
Hi,
I got an HM-3 dirt cheap a few years ago to use as a complement to my HM-2, but I always found it really hard to dial in. It's just got way too much top end sizzle regardless of where i set the EQ knobs, and there's not enough mids. So the other day I decided to try and turn the EQ section into HM-2 specs, and although it does sound a lot better now, I'm not quite there.
I need to state up front that I have no idea how to properly translate the values of the opamp EQ of the HM-2 to the...
