Are there any schematics floating around for any of the Robert Keeley mods, especially the one for the metal zone? I have a feeling that he might keep it under raps but...
I really want to do it but I can't afford US$75 (not that it's at all unreasonable, I'm just poor). I'm also not sure that paying for all the metal film caps would really make that much of a difference... but that's beside the point.
If anyones seen them or know what they might be, hook a brother up.
I'm sure he changes out one of the diodes with a red LED, as he does with the DS-1. That's probably at least part of his mod. And adds a 47pf cap across the diodes to smooth it out a bit because the Metal Zone has some obnoxious harsh clipping to it.
Yeah the metalzone on my pedalboard needs modding. It's too buzzy. I seriously need to make a nicer distortion like a DS-1 clone with a few mods :D
I'll bet that replacing some of the caps and adding the RED LED and 47pF cap etc. will make a HUGE change in the metal zone. They are hard core harsh~!!
You can do these mods yourself I'm sure. The parts would only cost $7-10 at the most~!!
I'll see what I can find out for you.

Check your email and pm Leftrights!!!!!

I'm also interested in any mods for the metal zone, i really like mine, but it's true that whe i turn the treble past 12 o'clock, it becomes really harsh.
By the way, Arn, have you seen my home page? I promised you some pics, so there they are!!
Great that you got a site up and working man! I stopped by and checked it out. Check your email for the mods!
Peace!
Arn C.
Hey Arn, could you send it to me too?
I think it must be how you EQ it. I have never got a buzzy sound out of mine. Only nice smooth soaring leads.
Any killer settings you recommend, Paul? I keep trying to make my MT-2 sound nice and smooth where it's harsh and sweet enough but not buzzy :?
And keep failing :mrgreen:
Here is how I have mine set:
Level 10:00 o'clock
Low 1:00 o'clock
Hi 8:00 o'clock
Middle 1:00 o'clock
Mid Freq 3:00 o'clock
Dist 11:00 o'clock
How it sounds also depends on your amp, how you EQ the amp, if you use the effects loop or not, the guitar you use, the pickups it has in it, how you set the tone control(s) on your guitar, etc., etc.
I like a darker, smoother tone. I HATE shrieking treble in my face.
Yeah, with the treble turned up the MT-2 seems to drown out any pitch in a note, just squealing treble :evil:
Cool. Thanks Arn. I',m going to have to give it a go.
By the way to give my two cents, I do like the sound of the Metal Zone... but also can't resist tearing apart pedals. :wink: The are the two versions out there, one with the stacked pots and one without.
Oh... there's a version without the 4-band EQ? That would indeed sound different. :wink:
The one i have is the old one, with the two dual pots (bass-treble, midrange-mids). I have found my sweet spot, but hey, if it could be tweaked a little to enhance it... :twisted:
Starting from Paul's setting I have now spent 4 hours tweaking and turning and it is now heavenly! Nice and crunchy but still clear enough for a smooth tone. When I decide to stop being lazy I'll post em if you like ;)
I would think the mods to both the SD-1 and the DS-1 could be incorparated since it has both kinds of clipping diodes, plus 2 inline Ge's. 8)
Hey Arn C.,Marcos or Leftrights could one of you send me a copy of those Keeley metalzone mods.Thanks
Hey don't forget me!
:D err... I have a Metal Zone right here waiting for the MODs...
May I receive the MODs too??? Please!

What about the switch that is in the keeley mod? Does that just change the clipping method?
Quote from: backintheussaWhat about the switch that is in the keeley mod? Does that just change the clipping method?
yes. It incorporates led's.
my sister played guitar for a couple of years, quit, and left me her Metal Zone :-D. I dont think that i would buy a thing like this, but its nice for _some_ stuff
It sounds very "digital" aka harsh, buzzy, etc.
So moral - how do these mods sound?!?
Listening to a Boss Metal Zone(& hating it) is what led me to develop the HMP.

Quote from: puretubebtw: I dig your new smileys....
Imported from another forum. Some friends of mine have a 'the Who' tribute band called 'the Wholigans'. //www.thewholigans.com They're on a 'tribute band' forum. They're pretty damn good. They tour on the continent a bit, but if you go see them take earplugs. Hiwatt amps on ten if you know what I mean!
I know it's really nothing new, but what do you think of the circuit(HMP) Ton? It has some rather unique characteristics compared to any other dirt box I've built or owned. It has this big rip-roaring fizzy sound, but hardly hums or feeds back(unless it's really cranked). I mean that the tone that it has, you would think there would be an 'out of control' element, but there's not. It's really well behaved. I'm mostly refering to the clipping sections. The parametric has not been extremely successful. It works...but I think I left out a buffer stage before it(trying to simplify) that may have been necessary for it to have a very dramatic sweep. I'm more player than EE(for certain), so I do a lot of guessing.

have only heard it thru my laptop yet;
have to download the sounds on other PC,
to send it thru some real speakers...
circuit looks good to me...

hello Arn C, can i have a copy of that schematic also ? thanks alot
In my opinion, indyguitarist's mod has more of an audible difference. It makes the mids EXCELLENT sounding, adding a nice crunch. Very 'brown sound.' Keeley's mod just makes it more transparent, much quieter, trims some highs, and note seperation is highly improved. My mod is also freakin' awesome too! I think I'll have some pics of my mod soon too for anyone interested. The topic which describes my mod is here... http://diystompboxes.com/sboxforum/viewtopic.php?p=195876#195876
does anyone have the detailed keeley mt-2 mods... ive searched the forum and found some... but not too sure whats goin on with whats listed... i bought brian's indy mod and tried the marchall mod but it turned my metal zone into a PISSED off Fuzz pedal i wanted to try the keeley mods but whats posted on brians keeley suggestions arent too clear... any help would be appreciated ... thnx in advance if you have any mods to send my way send them to thguy316@yahoo.com
Just an opinion........but... if Brian has a kit for it... I would at least consider supporting him and buying the kit. I have bought several of his kits and they are very well layed out. Text, parts lists, annotated pictures...
And he doesn't ask an unreasonable price for them either. About the price of a half decent 18 foot cord. Just a thought.....

Can u count me in as well? I have been searching for it
albert_wui1@yahoo.com
me too plz!!! omarmac@yahoo.com
well... me too then! :D I own one aswel and I DO like the sound (unlike many others!). But a modded MT-2 would be nice though. :wink:
rubifumi46@hotmail.com (just in case :P )
guitar_199>>>i purchased all of brians mods and i totally support the DIY community... but i found that brians metal zone mods turned my MT-2 into a PISSED off FUZZ pedal which is opposite of what i was looking for... Brian throws in bits and pieces of the keeley mod when u purchase the MT-2 mod but not so clearly... i hope u dont take this as an attack and if you do i appologize in advance....
as far as any mods??? ANYONE??? theguy316@yahoo.com
The mods do change the sound very much. They remove the honk of the pedal, but turn it into a fuzz. Changing clipping diodes changes the sound a lot!. I liked the sound of one LED and one SI, but if you leave in the two SI diodes it will be fuzzy, two LEDS makes it crunchier. I left out the 47 pf across the diodes because I like some of the high end shrill. But...they call them mods for a reason, they will change the sound A LOT.
Is anyone else having trouble finding some of the parts listed on the previous page? I've checked Mouser and Digikey and got nothing. Has anyone had any luck sourcing these?
"theguy316"
Heaven's no. Not at all sir.
We are all here to exchange information and help each other at what we do.
I loved what Brian's mod did for my DS-1 which is a different animal. You, on the other hand, had a less than positive experience on the MZ mod. You have enhanced my knowledge base..... so not at all!
HI,
I'd like to see a copy of the Keeley mods too if possible. I bought Brian's mt-2 mod and I have enjoyed it but I happened to pick up a second mt-2 and I would like to maybe give the keeley mod a try on it.
If anyone could email them to me that would be great. ripper_mb@yahoo.ca
Thanks again
One of the mods I recently did on my DIY MT-2 /no output buffer, true bypass switching/ is to change the clipping diodes to the Marshall's 5-diode clipping section /as found in JCM900 and JMP1/. To trim the harsh top end you can add a 47nF /not pF!/ cap in parallel with diodes.
My MT-2 setting:
Gain: 3-4 o'clock
Mid: 7 o'clock /completely cut/
Freq: 9-10 o'clock
High: 3-4 o'clock
Bass: 3-4 o'clock
I found my MT-2 to sound best when connected to the FX loop of a tube amp.
Enjoy!

Actually, there are software 'harvesters' all over the place. Anytime you have your email address on your site you will get harvested and your address will get sold to marketers (using the term loosely) who then use a service to send out several million email addresses. Also, some harvesting software will pick through the html and harvest addresses that way as well.

dont know why but that made me picture imagery from "The Matrix".
Hey,
Im looking to try to reproduce Keeley's Twilight Zone mod completely, including the switch... would someone be able to send me the keeley schematics, and/or help me with building the switch? You can send any help to punish77@hotmail.com Thanks!
i was wondering if you guys no what diodes do you have to replace for the keeley mod?
Hi, can anyone help me make a metal zone keeley mod that includes the twilight zone switch.
Instructions, diagrams or schematics can be incredibly helpful.
Thanks!
btw my email is ramaneek.gill(at)hotmail(dot)com
Hi guys,
I couldn't help but get interested in the metal zone mods you were discussing. If anyone could provide instructions for the twilight zone mods please let me know.
My mail address is:
